Gardening Know How advises completing six weather-sensitive garden tasks before a hard freeze: harvest tender crops, lift vulnerable tubers, protect plants, and drain outdoor water systems, among other steps. Timing varies by region, and the report’s supplied text details only the first two tasks, so the remaining four cannot be confirmed from the available material.
Gardening Know How has published a fall checklist urging gardeners to finish weather-sensitive chores before the first hard freeze, which the report defines as temperatures of 28°F (-2°C) or lower for several hours. Its supplied article text explains how to harvest tender crops and store vulnerable bulbs and tubers, while warning that freezing can damage plants and water-filled outdoor plumbing.
The report says gardeners should gather tomatoes, peppers, eggplants and basil before freezing weather. It recommends bringing in ripe tomatoes and mature green fruit with a glossy, pale-green surface; those green tomatoes can ripen indoors at room temperature. Small, hard tomatoes may not be mature enough to ripen. Basil can be pulled for drying or processing. By contrast, it says hardy crops including kale, collards, Brussels sprouts, carrots and parsnips can tolerate colder conditions.
For tender summer-flowering plants, the report advises gardeners in USDA zones 7 and colder to lift dahlias, cannas, calla lilies, caladiums, gladioli and tuberous begonias before the ground freezes. It says dahlias and cannas can be left until a light frost blackens their foliage, but gardeners should not wait for frozen soil. The article describes cutting stems to 4–6 inches, lifting clumps carefully with a garden fork and curing them in a dry, frost-free place.
After curing, the report recommends packing tubers in dry peat moss, vermiculite or wood shavings and storing them in a dark location at 40–50°F (4–10°C). It says dahlias may remain in the ground in zone 8 and warmer when the soil drains freely and receives protection. The source text provided for this article ends during that explanation and does not include the full details of the other four jobs named in its headline.
Protecting Plants and Outdoor Pipes
Freeze damage can affect more than foliage. The report warns that tender crops may be ruined, while tubers left in frozen soil can decompose. Water in pipes, outdoor faucets and irrigation lines can also freeze, with damage potentially going unnoticed until the system is used again. The article gives the example of discovering a split pipe when turning on a hose in spring.
The practical value of the advice depends on local conditions: completing relevant chores in time may help avoid replacing plants or repairing plumbing. These are the report’s stated risks, not a guarantee that doing the listed work will prevent all winter damage.

Freeze Dates Vary by Region
The report distinguishes a light frost around 32°F (0°C) from a hard freeze at 28°F or below that lasts several hours. It says tender annuals can be damaged by a light frost, while cold-tolerant vegetables may withstand it. A hard freeze can cause more extensive harm to plants and water systems. The article says frozen ground generally develops later, after sustained sub-freezing weather.
Timing differs across the United States. According to the report, gardens in northern USDA zones 3–5 often face hard freezes by mid-October, while milder zones 7–9 may not reach that threshold until late December or January. Those are broad regional estimates; a gardener’s local forecast and conditions determine the immediate deadline.
Four Checklist Tasks Not Supplied
The source material provided names a six-job checklist but contains detailed instructions for only two tasks: harvesting tender crops and lifting and storing tender tubers, bulbs and corms. It refers to overwintering plants and plumbing fixtures more generally, but does not supply the remaining four checklist items. They cannot be identified or described reliably from the available text.
The material also does not provide a publication date, location-specific forecast or information about whether a hard freeze is imminent for any particular reader. Its timing guidance is general, and local freeze dates can vary.
Check Local Forecasts and Prepare
Gardeners should use local forecasts to judge when temperatures may approach the hard-freeze threshold, rather than relying on a single calendar date. The report suggests having supplies such as frost fabric, storage crates, garden forks and insulated spigot covers ready before cold weather arrives. It also recommends keeping a thermometer available to track overnight temperatures.
Before acting on the full six-job list, readers would need the complete original report or other reliable guidance for the four tasks omitted from the supplied source. In the meantime, the two described jobs can be timed to local conditions, with extra care not to leave vulnerable tubers in ground that is about to freeze.
Key Questions
What temperature counts as a hard freeze in the report?
Gardening Know How defines a hard freeze as 28°F (-2°C) or lower for several hours. The report describes a light frost as occurring around 32°F (0°C).
Which crops should be harvested before freezing weather?
The report recommends harvesting tender crops such as tomatoes, peppers, eggplants and basil. It says mature green tomatoes can ripen indoors, while hardy crops such as kale, carrots and parsnips can tolerate colder weather.
When should gardeners lift dahlias and cannas?
The report says gardeners in zones 7 and colder can wait for an initial light frost to blacken dahlia and canna foliage, then lift the clumps before the ground freezes. It advises lifting tuberous begonias earlier as their leaves yellow.
Can dahlias stay in the ground over winter?
According to the report, dahlias can remain in the ground in zone 8 and warmer where the soil drains freely and the plants are protected. Local winter conditions still matter.
What are all six jobs in the checklist?
The supplied source text gives details for only two: harvesting tender crops and lifting and storing tender bulbs, tubers and corms. It does not include enough information to confirm the other four tasks.
