The best peace lily fertilizers offer gentle, manageable feeding rather than a push for rapid growth. My best overall pick is TPS Nutrients Peace Lily Liquid Fertilizer, a plant-specific liquid option; Miracle-Gro Tropical Houseplant Food stands out for shoppers who prefer a broader tropical-plant formula, while FOLLOWIN Peace Lily Liquid Fertilizer makes the shortlist with its stated 3-1-2 ratio and larger bottle. The main tradeoff is between targeted formulas and versatile houseplant foods, with sprays and concentrates offering different levels of convenience and dilution control. Formulation details and application instructions matter more than a peace-lily label alone. Read on for the full comparison and guidance on matching a fertilizer to your plant and routine.

Key Takeaways
- Plant-specific formulas lead this lineup: TPS Nutrients, GrowThrive, and several other options are labeled for peace lilies, while the Miracle-Gro foods are broader choices for tropical or indoor plants.
- 3-1-2 is a useful point of comparison, not a guarantee: FOLLOWIN, Gardenera’s concentrate and mist, GARDENWISE, and Leaves and Soul list this ratio, but buyers still need to follow each product’s directions.
- Application style changes the routine: Sprays and mists avoid measuring a liquid feed, while concentrates call for dilution but give the grower more control over the mix.
- Bottle size alone does not reveal value: The 16- and 21-ounce options offer more product by volume, but actual use depends on dilution instructions and feeding frequency.
- Organic positioning and convenience are separate choices: Kelp and organic-labeled options appeal to buyers seeking those formula cues, while ready-to-use sprays and familiar indoor plant foods may better suit low-measurement routines.

More Details on Our Top Picks
Gardenera Organic Liquid Kelp Fertilizer for Peace Lilies, 8 oz
Gardenera’s kelp concentrate is a distinctive choice for peace lily owners who want a seaweed-based feed rather than a conventional all-purpose formula. Its Ascophyllum nodosum ingredient and peace-lily-specific formulation are presented as support for foliage, roots, nutrient absorption, and flowering, while the 8-ounce bottle makes up to 45 gallons of solution. That yield gives it a different appeal from TPS Nutrients Peace Lily Liquid Fertilizer, which is described as a gentle 3:1:2 feed but does not list a comparable total yield. The tradeoff is that kelp-focused nutrition may not suit shoppers seeking a broadly usable fertilizer for a mixed plant collection. This pick also requires dilution, so it is less convenient than a ready-to-use spray. I’d choose it for a peace lily-focused routine where concentrated seaweed formula matters more than one-step application.
Pros:- Formulated specifically for peace lilies
- Ascophyllum nodosum seaweed is the featured ingredient
- An 8-ounce bottle makes up to 45 gallons of solution
- Suitable for indoor and outdoor peace lilies
Cons:- Requires dilution rather than direct application
- Its peace-lily focus may make it less useful for other plants
Best for: Peace lily owners who want a concentrated, seaweed-based fertilizer and are comfortable mixing it into water.
Not ideal for: People seeking one fertilizer for a varied houseplant collection or a ready-to-spray option; its formulation is peace-lily-specific and the concentrate requires mixing.
- Brand:Gardenera
- Product type:Liquid kelp fertilizer concentrate
- Plant compatibility:Peace lilies (Spathiphyllum)
- Featured ingredient:Ascophyllum nodosum seaweed
- Bottle size:8 fluid ounces
- Stated yield:Makes up to 45 gallons
- Country of origin:USA
Our verdict“Choose this concentrate if you want a peace-lily-specific kelp formula with a stated high solution yield and do not mind mixing.”
TPS Nutrients Peace Lily Liquid Fertilizer, 8 fl oz
TPS Nutrients Peace Lily Liquid Fertilizer is aimed at growers who want a liquid feed developed for potted peace lilies, with an emphasis on gentle, consistent nutrition. Its listed 3:1:2 mixing ratio gives buyers a specific formulation detail that the Gardenera Plant Superfood Spray does not provide; the spray instead emphasizes micronutrients and weekly leaf-and-stem application. TPS describes its fertilizer as supporting flowering, green leaves, and healthy roots, and as helping address nutrient-stress symptoms such as brown tips and yellowing. Those claims make it a more targeted soil-feeding option than a spray, but the product still needs to be mixed before use. It is also limited to peace lilies, unlike the broader-use spray. I’d put it ahead of spray formats for buyers who prefer a measured liquid feeding routine, not for anyone looking for a ready-to-use bottle.
Pros:- Formulated specifically for potted peace lilies
- Lists a 3:1:2 mixing ratio
- Designed for gentle feeding of sensitive roots
- Supports foliage, flowering, and root development
Cons:- Requires mixing before application
- Its peace-lily-specific formulation limits use on other plants
Best for: Peace lily owners who prefer a targeted liquid feed for potted plants and are willing to mix fertilizer as part of watering.
Not ideal for: Shoppers who want a ready-to-use spray or a fertilizer they can use across a mixed collection of houseplants.
- Brand:TPS Nutrients
- Form:Liquid
- Target plant:Peace lily
- Volume:8 fluid ounces
- Item weight:0.31 kg
- Mixing ratio:3:1:2
- Country of manufacture:USA
Our verdict“Pick TPS Nutrients if you want a peace-lily-focused liquid feed with a stated mixing ratio and do not mind preparing each application.”
Gardenera Plant Superfood Spray for Peace Lilies, 8 oz
Gardenera Plant Superfood Spray suits peace lily owners who favor leaf-and-stem application over mixing a soil feed. Its listed ingredients include vitamin B-1, glucose, iron, manganese, and zinc, giving it a micronutrient-led profile that differs from the seaweed-based Gardenera Liquid Kelp Fertilizer. The spray is described for indoor and outdoor plants and can be used weekly, so it may also fit households with plants beyond peace lilies. That wider use is an advantage over several peace-lily-only formulas here. The drawbacks are practical: weekly application calls for a regular routine, and the product data gives no dilution instructions or clear usage quantity per plant. Compared with TPS Nutrients Peace Lily Fertilizer Spray, this one names its key ingredients, but it still leaves application specifics unclear. I’d favor it for ingredient transparency, not for low-maintenance feeding.
Pros:- Lists vitamin B-1, glucose, iron, manganese, and zinc
- Spray application avoids mixing a concentrate
- Suitable for indoor and outdoor plants
- Described for year-round use
Cons:- Weekly application requires ongoing attention
- Product details do not provide dilution instructions
- No application quantity per plant is specified
Best for: Plant owners who prefer weekly foliar application and want a spray listing specific micronutrients for peace lily foliage and stems.
Not ideal for: People who want infrequent feeding or clear, quantified application and dilution directions before buying.
- Brand:Gardenera
- Model number:PSF-SPRAY-PEACE-LILY-8oz
- Volume:8 fluid ounces
- Form:Spray
- Use:Indoor and outdoor plants
- Recommended frequency:Weekly
- Key ingredients:Vitamin B-1, glucose, iron, manganese, zinc
- Part number:PSF-SPRAY-PEACE-LILY-8oz
Our verdict“Choose this spray if you want a micronutrient-listed foliar product and can follow a weekly routine despite limited application guidance.”
Peace Lily Fertilizer Spray, 16 fl oz
TPS Nutrients Peace Lily Fertilizer Spray is the most straightforward pick in this group for buyers who want a misting format rather than a concentrate to measure. Its 16-fluid-ounce bottle is larger than Gardenera Plant Superfood Spray’s 8-ounce size, which may suit someone who prefers to keep a single spray bottle on hand. The product is designed for indoor peace lilies and is described as supporting foliage, vitality, and flowering. Unlike the GrowThrive liquid, it does not require the listed 1:400 soil dilution; the tradeoff is that the product data gives no coverage, spray frequency, or dilution details. It is also peace-lily-specific, while Gardenera’s spray is described for indoor and outdoor plants. I’d select this for simple indoor application, but not if detailed dosing guidance or use across a broader plant collection is a priority.
Pros:- Spray application avoids preparing a diluted feed
- Designed specifically for indoor peace lilies
- 16-fluid-ounce volume exceeds the 8-ounce Gardenera spray
- Described as supporting foliage, vitality, and flowering
Cons:- No coverage or dilution details are provided
- No application frequency is specified in the product data
- Formulated specifically for peace lilies
Best for: Indoor peace lily owners who want a spray format and prefer a larger bottle over a concentrated product that needs mixing.
Not ideal for: Buyers who need stated coverage, frequency, or detailed application directions, or who want one product for multiple plant types.
- Brand:TPS Nutrients
- Form:Liquid
- Application method:Spray
- Target species:Peace lilies
- Volume:16 fluid ounces
- Number of items:1
- Made in:USA
Our verdict“Choose this larger spray if ease of application for indoor peace lilies matters more to you than detailed dosing guidance.”
GrowThrive Organic Peace Lily Liquid Fertilizer, 10 oz
GrowThrive Organic Peace Lily Liquid Fertilizer takes a different route from the kelp-based Gardenera concentrate: its featured distinction is a multi-strain microbial formula with over 5.9 billion CFUs per fluid ounce. The product is designed for all peace lily varieties, including standard, miniature, and giant plants, and its 1:400 dilution ratio gives buyers a clear starting point for soil application. A measuring cap is included, although it has no graduated markings, so accurate measuring may take extra care. Compared with TPS Nutrients Peace Lily Liquid Fertilizer, GrowThrive offers more explicit dilution instructions and a stated bacterial count, but it still requires mixing and does not provide a ready-to-use option. I’d choose it for growers drawn to microbial root support and clear dilution guidance, while skipping it if cap-based measuring feels imprecise.
Pros:- Multi-strain microbial formula lists over 5.9 billion CFUs per fluid ounce
- Formulated for all peace lily varieties
- Provides a specific 1:400 dilution ratio
- Includes a measuring cap
Cons:- Requires dilution before soil application
- Measuring cap has no graduated markings
- Product data does not specify how much mixed solution to apply per plant
Best for: Peace lily growers of standard, miniature, or giant varieties who want a microbial liquid feed and can measure a concentrated 1:400 mix.
Not ideal for: People who want a ready-to-use product or precise measuring from a graduated cap; the included cap has no markings.
- Brand:GrowThrive
- Form:Liquid
- Volume:300 ml (10 oz)
- Weight:350 g
- Mixing ratio:1:400
- Application method:Dilute with water and apply to soil
- Target plants:All peace lily varieties
- Bacterial count:Over 5.9 billion CFUs per fluid ounce
- Pack size:1
Our verdict“Pick GrowThrive if microbial root support and an explicit dilution ratio appeal to you, and you are comfortable measuring without marked cap graduations.”
Miracle-Gro Tropical Houseplant Food, Liquid Fertilizer, 8 fl oz, 2-Pack
Broad tropical-plant use is the advantage here: this liquid food suits peace lilies alongside plants such as pothos, monstera, and spider plants. Its listed magnesium, manganese, copper, iron, and zinc add micronutrients beyond the basic feeding, and the formula starts feeding instantly. Compared with the peace-lily-specific FOLLOWIN 3-1-2, this pick is less narrowly tailored, but it may fit a home where several tropical houseplants share a feeding routine. The tradeoff is its weekly spring-and-summer schedule; it is not presented as a year-round option, and frequent feeding calls for attention to the label directions. Choose it for a mixed tropical collection rather than for the most targeted peace lily formula.
Pros:- Suitable for peace lilies and a broad range of tropical houseplants
- Includes magnesium, manganese, copper, iron, and zinc
- Starts feeding instantly
- Two 8 fl oz bottles provide a paired supply
Cons:- Use is recommended weekly only during spring and summer
- Less specifically targeted to peace lilies than FOLLOWIN or Gardenera’s peace lily formulas
Best for: Plant owners feeding a peace lily alongside several tropical houseplants who want one liquid fertilizer for the collection.
Not ideal for: Peace lily growers seeking a formula explicitly made for that plant or a feeding plan specified for seasons beyond spring and summer.
- Product type:Liquid fertilizer
- Bottle volume:8 fl oz each
- Pack size:2-pack
- Application frequency:Once per week
- Recommended season:Spring and summer
- Micronutrients:Magnesium, manganese, copper, iron, and zinc
- Suitable plants:Tropical houseplants, including peace lilies, spider plants, ZZ plants, snake plants, croton, pothos, monstera, and fiddle-leaf figs
Our verdict“Choose this two-bottle option if you want to feed a peace lily and other tropical houseplants with the same product.”
FOLLOWIN Peace Lily Liquid Fertilizer, 3-1-2 NPK, 21 fl oz
Peace lily-specific feeding and a clearly stated dilution make FOLLOWIN a strong pick for growers comfortable mixing fertilizer into water. Its 3-1-2 NPK blend is paired with EDTA-chelated micronutrients, including calcium, magnesium, iron, and zinc; the measuring cap helps make the stated mix less guesswork-prone. The bottle is described as yielding up to 48 gallons when diluted as directed, a different approach from the ready-to-use Gardenera Peace Lily Spray, which skips measuring but offers less control over mixing. FOLLOWIN’s tradeoff is that every application requires dilution, so it suits an attentive routine better than quick, no-prep care. The supplied directions specify one cap in 0.8 gallon of water.
Pros:- 3-1-2 formula is targeted to peace lilies and other houseplants
- Includes EDTA-chelated micronutrients
- Measuring cap supports consistent dilution
- Stated yield is up to 48 gallons when mixed as directed
Cons:- Requires dilution before application
- Mixing directions require attention to the stated water volume
- Broader houseplant use makes it less exclusively peace-lily-focused than a single-plant formula
Best for: Peace lily owners who want a concentrated, plant-targeted formula, value a measured mixing cap, and are comfortable preparing diluted feed.
Not ideal for: Growers who want a ready-to-spray product or prefer not to measure and dilute fertilizer before use.
- NPK ratio:3-1-2
- Liquid volume:21 fl oz
- Form:Liquid concentrate
- Yield:Up to 48 gallons when diluted as directed
- Mixing ratio:1 cap (10 ml) per 0.8 gallon of water
- Micronutrients:EDTA-chelated calcium, magnesium, iron, zinc, copper, manganese, and boron
- Target plants:Houseplants, including peace lilies
- Model number:FL010109
Our verdict“Pick FOLLOWIN if you want a concentrated, peace lily-targeted feed and do not mind mixing it before watering.”
Gardenera Peace Lily Spray Fertilizer Mist, 3-1-2, 8 oz
If measuring concentrate feels like extra work, the ready-to-use spray format is this product’s main draw. Gardenera offers a 3-1-2 blend formulated for peace lilies, with use described as weekly or at watering time. That makes it more convenient to prepare than the concentrated FOLLOWIN Peace Lily Liquid Fertilizer, which must be diluted; in return, FOLLOWIN provides a stated large diluted yield and a measuring cap. This mist is a more focused choice than Miracle-Gro Tropical Houseplant Food, which is designed for a wider tropical collection. The tradeoff is narrower use: the listing targets peace lilies rather than a whole houseplant collection. Follow the directions and avoid overwatering, since adding liquid care without accounting for existing soil moisture can complicate watering.
Pros:- Ready-to-use spray avoids dilution and mixing
- 3-1-2 blend is formulated for peace lilies
- Can be used weekly or at watering time as directed
- Listed for indoor or outdoor peace lilies
Cons:- Peace-lily-focused formula is less suited to feeding a varied plant collection
- Directions caution users to avoid overwatering
- Single 8 oz bottle offers less volume than FOLLOWIN’s 21 fl oz concentrate
Best for: Peace lily owners who prioritize a pre-mixed spray and want to avoid measuring concentrate.
Not ideal for: People feeding many types of houseplants or anyone seeking a concentrate with a stated high diluted yield.
- NPK ratio:3-1-2
- Volume:8 oz
- Form:Ready-to-use liquid mist
- Pack count:1
- Target plant:Peace lilies
- Use setting:Indoor or outdoor
- Use guidance:Weekly or at watering time; shake well and avoid overwatering
Our verdict“Choose this mist if you want a peace lily-specific fertilizer that is ready to use straight from the bottle.”
Gardenera Liquid Peace Lily Fertilizer Concentrate, 3-1-2, 8 fl oz
This Gardenera concentrate suits peace lily owners who prefer a specific mixing ratio over an off-the-shelf spray. The 3-1-2 liquid is formulated for peace lilies, with directions to mix 1 teaspoon per gallon of water. Compared with Gardenera’s Peace Lily Spray, it takes more preparation but lets the grower make a diluted watering solution instead of applying a ready-to-use mist. The product is described as 100% organic, though the supplied information does not independently verify that claim or detail its ingredient list. That makes the stated ratio and target plant clearer decision points than claims about results. It is less convenient than the spray and less fully specified than FOLLOWIN, which lists chelated micronutrients and a measuring cap.
Pros:- 3-1-2 formula is formulated specifically for peace lilies
- Provides a clear mixing ratio of 1 teaspoon per gallon
- Concentrated form lets the grower prepare diluted feed
- Described by the product as 100% organic
Cons:- Must be diluted before use
- Organic and performance claims are not independently verified in the supplied product information
- Provided specifications do not list micronutrients or a stated yield
Best for: Peace lily growers who want a plant-targeted concentrate with a stated teaspoon-per-gallon mixing ratio.
Not ideal for: Buyers who want ready-to-use application, detailed micronutrient information, or independently substantiated organic credentials.
- Formula:3-1-2
- Form:Liquid concentrate
- Volume:8 fl oz
- Target plant:Peace lily
- Mixing ratio:1 teaspoon per gallon of water
- Pack count:1
- Product description:Described as 100% organic
Our verdict“Pick this concentrate if you want a peace lily-specific formula with a straightforward dilution ratio and accept limited ingredient detail.”
Miracle-Gro Indoor Plant Food, Liquid, 8 oz Bottles, 2-Pack
Miracle-Gro Indoor Plant Food makes sense when a peace lily is just one part of a larger indoor collection. It feeds a range of indoor plants, and the two 8 oz bottles can be applied directly to soil or diluted in water. That flexibility separates it from the pre-mixed Gardenera Peace Lily Spray, which is more plant-specific but does not offer the same broad listed use. The product is described as feeding instantly and includes peace lilies among suitable plants, alongside flowers, vegetables, and herbs. The tradeoff is that it is a general indoor formula, not a peace lily-focused 3-1-2 product like FOLLOWIN or Gardenera’s concentrate. Its listed weekly application also calls for a regular routine, and it is intended for indoor container plants.
Pros:- Suitable for peace lilies and a wide range of indoor plants
- Can be applied directly to soil or diluted in water
- Two 8 oz bottles provide 16 fl oz total
- Described as feeding instantly
Cons:- General-purpose indoor formula rather than a peace lily-specific blend
- Listed for weekly application, requiring a regular feeding routine
- Intended for indoor container plants
Best for: Indoor gardeners feeding a peace lily along with other houseplants, flowers, vegetables, or herbs who want direct-application or diluted-use flexibility.
Not ideal for: Buyers seeking a fertilizer formulated specifically for peace lilies or a product listed for outdoor use.
- Form:Liquid
- Bottle size:8 fl oz each
- Pack quantity:2
- Total volume:16 fl oz
- Application:Apply to soil or dilute 4 pumps in 1 quart of water
- Application frequency:Once a week
- Suitable plants:Indoor plants, including houseplants, snake plants, croton, peace lilies, flowers, vegetables, and herbs
- Model number:3037202
Our verdict“Choose this two-pack if you want one flexible liquid food for a peace lily and a varied indoor plant collection.”
GARDENWISE Peace Lily Liquid Fertilizer, 3-1-2, 8 fl oz
The clearest reason to choose GARDENWISE is its peace-lily-specific formula: its 3-1-2 ratio includes micronutrients and is intended for both watering and foliar application. The 1:128 dilution means a small amount of concentrate makes a large volume of feed, though careful measuring matters. Compared with the broader-use Houseplant Resource Center Organic Liquid Indoor Plant Food, this is the more focused pick for someone feeding Spathiphyllum rather than a mixed collection. That specialization is also its main limitation: the product data does not position it as a general houseplant fertilizer. Its 8-ounce bottle is compact, and the description supplies no schedule or dose beyond dilution, so buyers should follow the label rather than assume frequent feeding is appropriate.
Pros:- Formulated specifically for peace lilies
- 3-1-2 nutrient ratio includes essential micronutrients
- Can be applied through watering or as a foliar spray
- Concentrated 1:128 dilution stretches the 8-ounce bottle
Cons:- Its peace-lily focus limits its stated suitability for other plants
- Requires accurate dilution before either application method
- The supplied product details do not specify a feeding schedule
Best for: Peace lily owners who want a plant-specific 3-1-2 concentrate and value having both watering and foliar application options.
Not ideal for: People feeding a varied houseplant collection who would rather use one broadly targeted formula than buy a fertilizer designed specifically for peace lilies.
- Brand:GARDENWISE
- Fertilizer ratio:3-1-2
- Form:Liquid
- Dilution ratio:1:128
- Volume:8 fluid ounces
- Designed for:Peace lilies (Spathiphyllum)
- Application methods:Watering or foliar application
- Manufacturer:Summit Sales Company LLC
Our verdict“Choose GARDENWISE if peace lilies are your main feeding priority; pick Houseplant Resource Center instead for a formula aimed at a wider range of houseplants.”
Houseplant Resource Center Organic Liquid Indoor Plant Food, 8 oz
For a home with peace lilies alongside pothos, monstera, or other listed houseplants, Houseplant Resource Center is the most versatile fit in this group. Its 3-1-2 ratio matches the nutrient profile of the GARDENWISE and Leaves and Soul options, while chelated micronutrients and a urea-free formula give this product a distinct sensitive-root positioning. It is applied diluted during watering, with a watering can or spray bottle, so it does not offer the same clearly stated soil-or-bottom-watering choice as HiThrive. The tradeoff for broad plant coverage is that it is not tailored solely to peace lilies; buyers seeking a dedicated Spathiphyllum product may prefer GARDENWISE. Dilution is required, so it is less convenient than any ready-to-use option.
Pros:- 3-1-2 NPK ratio with chelated micronutrients
- Urea-free formula is positioned for sensitive roots
- Suitable for a range of listed houseplants, including peace lilies
- Can be applied with a watering can or spray bottle
Cons:- Must be diluted before application
- Broad houseplant targeting is less specialized than GARDENWISE or HiThrive
- The provided product details do not give a dilution ratio
Best for: Indoor gardeners who feed peace lilies as part of a collection that also includes plants such as pothos, monstera, cacti, or snake plants.
Not ideal for: Buyers who want a peace-lily-only fertilizer or a ready-to-use feed, since this formula is broadly targeted and must be diluted.
- Brand:Houseplant Resource Center
- Form:Liquid
- NPK ratio:3-1-2
- Volume:8 fluid ounces
- Application method:Dilute and apply with a watering can or spray bottle
- Urea-free:Yes
- Target plants:Houseplants including pothos, peace lily, monstera, cactus, dracaena, snake plant, and spider plant
- Country of manufacture:USA
Our verdict“Choose this for one diluted fertilizer across a mixed houseplant collection; choose HiThrive if you want a product formulated specifically for peace lilies.”
HiThrive Peace Lily Liquid Fertilizer, 16 oz
HiThrive earns its place for peace lily owners who want a larger-format, plant-specific concentrate: the 16-ounce bottle makes up to 96 gallons, and the listed nutrients include nitrogen, phosphorus, potassium, calcium, magnesium, and zinc. Soil application and bottom watering provide useful flexibility for established plants or a group of pots. The volume is twice that of the 8-ounce GARDENWISE bottle, while both are positioned specifically for peace lilies; HiThrive also names support for foliage, roots, and blooms. Its stated 1:10 mixing ratio is less dilute than GARDENWISE’s 1:128, so do not compare bottle yield without following each product’s label directions. Like GARDENWISE, this is a less flexible choice for feeding plants beyond its target species, and measuring before use is required.
Pros:- Formulated specifically for peace lilies
- 16-ounce bottle is stated to make up to 96 gallons
- Lists macro- and micronutrients, including calcium, magnesium, and zinc
- Offers soil application or bottom watering
Cons:- Requires dilution before use
- Peace-lily-specific positioning makes it less suitable as a single feed for assorted houseplants
- The listed 1:10 mixing ratio calls for careful measuring
Best for: Peace lily owners with several plants who want a dedicated liquid feed that can be applied to soil or by bottom watering.
Not ideal for: People seeking one fertilizer for a varied indoor garden, or anyone who prefers a ready-to-use product without mixing concentrate.
- Brand:HiThrive
- Form:Liquid
- Volume:16 fluid ounces
- Coverage:Makes up to 96 gallons
- Mixing ratio:1:10
- Target plant:Peace lily
- Key nutrients:Nitrogen, phosphorus, potassium, calcium, magnesium, and zinc
- Application methods:Soil application or bottom watering
Our verdict“Choose HiThrive for a larger supply and bottom-watering flexibility for peace lilies; choose Houseplant Resource Center for broader plant coverage.”
Leaves and Soul Peace Lily Liquid Fertilizer Concentrate, 3-1-2, 8 fl oz
Leaves and Soul combines a peace-lily target with stated suitability for other indoor plants, making it a middle ground between dedicated options such as HiThrive and the broad-use Houseplant Resource Center formula. Its 3-1-2 formula gives peace lily owners a familiar ratio, while the 8-ounce concentrate is made in the USA. The key drawback is its listed 1:4 mixing ratio: compared with GARDENWISE’s 1:128 dilution, that calls for a much larger proportion of concentrate per mix, so the stated bottle sizes alone do not tell you which lasts longer. Product details do not list micronutrients, application methods, or coverage, leaving less guidance for buyers than HiThrive provides. It suits shoppers who want a flexible concentrate, but not those who need detailed feeding instructions from the supplied specs.
Pros:- 3-1-2 formula designed for peace lilies and other indoor plants
- Concentrated liquid format mixes with water before use
- Made in the USA
- Can serve buyers seeking a formula with both peace lily and indoor-plant targeting
Cons:- Requires dilution before use
- Listed 1:4 mixing ratio uses a larger proportion of concentrate than GARDENWISE’s 1:128 ratio
- Provided details do not specify micronutrients, application methods, or bottle coverage
Best for: Peace lily owners who also want a concentrate described for other indoor plants and are comfortable following its dilution directions.
Not ideal for: Buyers who want a stated micronutrient list, application options, or coverage guidance, or who prefer a more highly diluted concentrate such as GARDENWISE.
- Brand:Leaves and Soul
- Formula:3-1-2
- Form:Liquid concentrate
- Volume:8 fluid ounces
- Mixing ratio:1:4
- Target species:Peace lily
- Other stated use:Other indoor plants
- Made in:USA
Our verdict“Choose Leaves and Soul if you want a 3-1-2 concentrate described for peace lilies and other indoor plants, but favor HiThrive for clearer nutrient and application details.”

How We Picked
I compared the 14 listed fertilizers on factors that affect peace lily care: whether the product is labeled for peace lilies or general indoor and tropical plants, the stated nutrient information, application format, bottle size, and how much measuring or dilution the routine may require. I also weighed versatility, since a general houseplant food can serve a mixed collection, against specificity for growers who want a product marketed for this plant.
The ranking favors products with a clear fit for peace lilies, useful formulation details, and a practical application style. A stated 3-1-2 ratio helps shoppers compare formulas but does not prove one is better for every plant or home. Sprays rank for convenience rather than feeding control; concentrates can suit careful mixers but require attention to directions. Where the supplied product details do not establish ingredient amounts, dilution rates, or feeding schedules, I avoid treating those claims as proven advantages.

Factors to Consider When Choosing Best Peace Lily Fertilizers
Choosing a peace lily fertilizer is less about chasing the strongest formula and more about selecting a feeding method you can use accurately. These broader checks can help you compare plant-specific products, general houseplant foods, sprays, and concentrates without relying on label wording alone.
Match the formula to your plant collection
A peace-lily-specific label can make shopping simpler, but it does not automatically mean the fertilizer suits your plant better than a general indoor formula. If you care for several tropical houseplants, a broader product may reduce the number of bottles you keep and make routine feeding easier. A dedicated option may be more appealing when you want instructions framed around peace lilies. Compare the actual label directions and nutrient information rather than choosing by the plant name alone. Avoid assuming a product marketed for one species is safe at any dose. For a mixed collection, versatility may matter more than narrow labeling; for a single peace lily, clear, manageable directions may matter most.
Read the nutrient ratio in context
A listed ratio such as 3-1-2 gives a quick view of the relative amounts of nitrogen, phosphorus, and potassium, but it does not tell you the full feeding plan. Check whether the label also gives a dilution rate, application method, and frequency. Those instructions affect how much fertilizer the plant receives more directly than the ratio printed in a product name. Do not assume that a higher concentration means better growth or that a particular ratio suits every growing setup. Peace lilies in low light or slow growth may use less than a vigorously growing plant. If nutrient details are limited, prioritize clear usage directions over a formula claim you cannot compare fully.
Choose a delivery method you can use consistently
Liquid feeds and concentrates require measuring, while sprays and mists can reduce preparation steps. That convenience has a tradeoff: a spray’s directions may differ from a root-applied liquid, so do not treat the formats as interchangeable. Concentrates can give you more control over dilution and may be practical for regular feeding, but inaccurate mixing can lead to overapplication. Ready-to-use formats suit people who want fewer steps, though they may offer less flexibility in dose. Think about where you will apply the product and whether the instructions fit your existing watering routine. The best format is the one you can use correctly, not simply the one with the shortest label description.
Compare bottle size with real use
A larger bottle can reduce how often you need to restock, but volume alone cannot tell you how long it will last. Concentrated products may make many diluted applications from a small container, while a ready-to-use product may be used more quickly. Before comparing package sizes, check the amount needed per application and the recommended interval. Multi-bottle packs may suit households feeding several plants, but can be unnecessary for one slow-growing peace lily. Avoid buying extra product solely because the package appears larger. Storage space and the fertilizer’s label guidance matter as much as bottle capacity.
Treat organic and kelp claims as preferences, not feeding instructions
Organic-labeled and kelp-based products may appeal to shoppers who prefer those ingredient cues, but those labels do not replace application directions. Check the product information for how to dilute or apply it, and follow the stated schedule instead of adding extra feed because the formula sounds gentle. Organic positioning alone does not tell you the nutrient concentration or how a product will fit your plant’s needs. If you are comparing a kelp option with a conventional houseplant food, look for the same practical details on both labels. A buyer prioritizing a specific ingredient approach may accept a narrower use case. A buyer focused on ease may prefer a formula with straightforward directions instead.
Scale feeding to growth and growing conditions
Fertilizer choice cannot compensate for conditions that limit growth, such as unsuitable light, watering problems, or a plant that is not actively growing. Follow the product label and avoid increasing the dose to address yellowing or drooping before checking basic care. More frequent feeding is not automatically better, particularly when a plant is growing slowly. A cautious routine makes it easier to spot how the plant responds without changing several parts of its care at once. Keep the fertilizer schedule consistent with the label and your plant’s growth pattern. If you are unsure between products, choose the one with directions you can follow precisely.
Frequently Asked Questions
Should I choose a peace-lily-specific fertilizer or a general indoor plant food?
Choose a peace-lily-specific product if you want a label and directions aimed at that plant. A general indoor or tropical houseplant food can be more convenient if you feed several kinds of plants and prefer one product for the collection. Compare nutrient details and application instructions before deciding, since a specific name does not by itself establish a better formula. The Miracle-Gro options in this roundup are broader-use choices, while products such as TPS Nutrients and GARDENWISE are labeled for peace lilies. Pick based on the plants you feed and the clarity of the directions, not the label category alone.
Is a 3-1-2 fertilizer automatically the right choice for my peace lily?
No ratio is automatically right for every peace lily or care routine. The 3-1-2 label makes several products in this roundup easier to compare, but it does not reveal the recommended dose, frequency, or full application method. Read those directions before buying and use the product as labeled. Your plant’s growth and care conditions also affect how often feeding makes sense. If two options share the same ratio, compare their formats and instructions rather than treating the matching numbers as proof they perform alike.
Are fertilizer sprays a good substitute for liquid feed?
A spray can suit buyers who want fewer measuring steps, but it should not be assumed to work exactly like a liquid feed applied during watering. Follow the spray’s own directions, including where and how often to apply it. If you want more control over dilution, a concentrate may fit better, provided you are comfortable measuring it accurately. Sprays in this roundup include Gardenera’s 3-1-2 mist and other peace lily spray products. Choose by the application routine you can follow, not by convenience alone.
Does a bigger bottle mean I am getting better value?
Not necessarily: bottle volume does not show how many applications it provides. A concentrate can be diluted, while a ready-to-use product may require more liquid per use. Check the label for the amount per application and the recommended schedule before comparing package sizes. Larger formats such as FOLLOWIN’s 21-ounce bottle or HiThrive’s 16-ounce bottle may appeal to people feeding more plants, but may be more product than a single plant needs. For one peace lily, a smaller bottle with clear directions can be the more practical purchase.
Should I fertilize a peace lily that is drooping or developing yellow leaves?
Do not assume fertilizer is the fix for drooping or yellowing. Those signs can have causes unrelated to feeding, including watering or growing conditions, so check the plant’s care before adding nutrients. Extra fertilizer may add stress if the plant is not actively growing or is already receiving more than the label recommends. If you decide to feed, follow the chosen product’s instructions rather than increasing the dose to chase a quick change. A fertilizer is a routine input, not a substitute for identifying the cause of a plant problem.
Conclusion
For most shoppers, TPS Nutrients Peace Lily Liquid Fertilizer is my best overall choice because it is explicitly made for peace lilies and keeps the comparison centered on this plant. For a more versatile option, I would pick Miracle-Gro Tropical Houseplant Food; it makes more sense for a collection of tropical plants than for someone seeking a narrowly targeted label. FOLLOWIN is a practical pick for buyers drawn to a stated 3-1-2 ratio and a larger bottle, while Gardenera’s 3-1-2 concentrate is better suited to people comfortable measuring and diluting. Beginners should favor whichever product has the clearest instructions and a format they can apply accurately, rather than choosing by formula claims alone. For shoppers who specifically want a spray or an organic- or kelp-labeled option, compare the relevant Gardenera sprays, Gardenera Organic Liquid Kelp, and Houseplant Resource Center against their preferred routine and label directions.
