A Homes & Gardens gardening report identifies seven perennials that gardeners can divide in October to renew older or crowded clumps and create additional plants. The supplied material gives detailed instructions for bee balm, phlox, coneflower and bleeding heart; it does not include the remaining three plant profiles or establish that dividing guarantees more blooms.
Homes & Gardens has published an October guide to dividing seven established perennials, recommending the garden task as a way to refresh older, crowded plants and produce additional divisions. The report says gardeners should allow at least four weeks before the first ground frost for transplanted sections to establish; its supplied excerpts give specific instructions for four of the seven plants.
The report frames division as both a maintenance task and a low-cost way to add plants to beds and borders. A clump that has become crowded, spread beyond its allotted space or flowered less well may be a candidate. October can offer warm soil and moisture, but the report’s timing advice is conditional: there should be at least four weeks before ground frost after transplanting. Local conditions and the plant’s needs still matter.
For bee balm, or monarda, the report recommends dividing every three years, in spring or fall. The plant spreads through underground rhizomes; dividing can limit its spread and remove an unproductive woody center. Each new piece should be planted in a sunny spot with moist, well-drained soil. The article also says smaller clumps may be less susceptible to powdery mildew than large ones.
Perennial phlox can develop a bare center as it spreads outward, the report says. Gardeners are advised to divide it every few years, making sections with at least two shoots and healthy roots. For fall divisions, the report recommends a thick mulch layer to help limit frost heave, when repeated freezing and thawing can lift plants from the soil. For coneflower, it suggests division every three to four years; each piece should include rhizome, healthy fibrous roots and two or three above-ground stems. Water divisions thoroughly and keep the soil moist while they establish.
Refreshing Crowded Garden Clumps
Dividing perennials can address a practical garden problem: plants that have become congested, spread too far or weakened at the center. It also lets gardeners reuse plants already growing in their gardens rather than buying every new addition. The report presents improved flowering as a potential benefit of renewing some clumps, not a guaranteed result for every plant or garden.
The method is not simply a matter of cutting every mature plant into pieces. Species differ in how often they should be divided and what a viable division needs. The report’s advice points to healthy roots and suitable shoots or buds as important for successful replanting, while the frost deadline makes local climate a key part of the decision.

October Division and Frost Timing
The article is presented as a second installment in a seasonal series. Its author refers readers to a 2025 article about seven other perennials, including hostas, daylilies, peonies and black-eyed Susan. The current supplied report names seven additional candidates, but the available material provides detailed descriptions for only bee balm, phlox, coneflower and bleeding heart.
October is not a fixed planting window everywhere. The report links the opportunity to warm soil and moisture, while also setting a minimum of four weeks before the first ground frost. That means a gardener’s local forecast and typical frost dates affect whether fall division is appropriate. The excerpt does not provide region-specific planting calendars.
It describes bleeding heart, now classified as Lamprocapnos spectabilis and formerly known as Dicentra spectabilis, as a shade-tolerant perennial with heart-shaped flowers in late spring and early summer. For fall division, each section should have an eye bud and healthy roots, and should be replanted at the same depth as the original clump. The supplied text ends before its full planting guidance is given.
“The window for dividing plants is open” if there are “at least four weeks after transplanting until the first ground frost.”

Missing Plant Profiles and Local Conditions
The supplied source material announces seven plants but includes detailed profiles for only four. It does not identify the other three in the excerpt, so their names and recommended division methods cannot be reported from this material. The bleeding-heart instructions are also incomplete because the supplied text stops after saying to replant divisions at the original depth.
The report does not provide location-specific frost dates or evidence quantifying how much division improves flowering. Its bloom-related benefit is guidance about gardening practice, not a measured guarantee. Whether October is suitable depends on local frost timing, soil and the condition of the plant.
Check Frost Dates Before Dividing
Gardeners considering the task should first check whether their area is likely to provide the report’s four-week establishment window before ground frost. They can then inspect established clumps for crowding or decline and follow species-specific directions rather than applying one method to every perennial. Newly planted divisions should be watered as directed; phlox divisions may need mulch to reduce frost-heave risk.
The report’s remaining three plant profiles and complete bleeding-heart instructions are not present in the supplied material. Until those details are available, the article supports advice only for the four plants described here, and no further dates or outcomes are confirmed.
Key Questions
Why divide perennials in October?
The Homes & Gardens report says division can renew older or crowded clumps and provide additional plants. It describes October soil warmth and moisture as helpful, but says there should be at least four weeks before the first ground frost.
Which plants does the supplied report explain how to divide?
The available profiles give instructions for bee balm, perennial phlox, coneflower and bleeding heart. The report refers to seven plants in total, but the supplied material does not identify or describe the other three.
How many shoots should a phlox division have?
The report recommends sections with at least two shoots and a portion of healthy roots. It also advises adding a thick mulch layer after fall division to help prevent frost heave.
Can all perennials be divided in October?
The report does not say that every perennial is suitable. Its guidance concerns selected plants, and fall division is conditional on having at least four weeks before ground frost. Local conditions and plant-specific instructions should guide the timing.
