A Homes & Gardens gardening report lists seven perennials that gardeners can divide in October to rejuvenate older clumps and create new plants. The supplied report gives care instructions for bee balm, phlox, coneflower and bleeding heart; it names three more plants but provides no details about them. Dividing is recommended only when plants have at least four weeks to establish before the first ground frost.
Homes & Gardens has published an October gardening report recommending that gardeners divide established perennials to rejuvenate declining clumps and create plants for other parts of the garden. The guidance names seven candidates, though the supplied article text provides specific instructions for only four and says dividing should be done with at least four weeks before the first ground frost.
The report says October can be a useful period for the work because soil is warm and moisture is abundant. Dividing can help older plants that flower less strongly, as well as large clumps that have outgrown their space. The article frames it as a way to propagate existing plants rather than buy new ones; it does not quantify likely cost savings or bloom increases.
For bee balm, or Monarda, the report recommends division about every three years, in spring or fall. It says gardeners can discard an unproductive woody center and replant healthy sections in a sunny spot with moist, well-drained soil. The article also says smaller clumps may be less susceptible to powdery mildew.
For phlox, each division should have at least two shoots and healthy roots. The report recommends a sunny planting site and a thick mulch layer after fall division to reduce frost heave, when soil freezing and thawing can lift plants. For coneflower, it suggests dividing every three to four years and retaining a section of rhizome, fibrous roots and two or three stems. New pieces should be replanted at their original depth and watered thoroughly.
Renewing Clumps Before Winter
The advice matters to gardeners with established borders because dividing can address two common problems at once: crowded growth and weaker flowering. Replanting healthy sections also offers a way to fill gaps in a garden using plants already on hand. These are practical benefits described by the publication, not a guarantee that every divided plant will produce more blooms.
Timing is a key limitation. A division needs time to establish before the ground freezes, and the report sets a minimum of four weeks before the first ground frost. Gardeners whose frost arrives soon, or whose local conditions are unusually dry or wet, may not have the same window. The article does not provide region-specific calendars.
The selected plants also illustrate that division is not one-size-fits-all. Some need a particular number of shoots or buds, while others are best divided on a multi-year cycle. Following the plant-specific instructions may help retain the roots and growing points needed for successful replanting.

Which Plants the Report Names
The report presents the list as a follow-up to a 2025 article about seven other perennials, including hostas, daylilies, peonies and black-eyed Susan. Its 2026 list names bee balm, phlox, coneflower and bleeding heart in the supplied material. Although the introduction promises seven plants, the source text provided here ends partway through the bleeding-heart instructions and does not show the remaining three entries.
For bleeding heart, also known by the botanical name Lamprocapnos spectabilis, the report says each fall division should include healthy roots and an eye bud, which can sprout the following year. It describes the plant as suited to shade and warns that full sun can damage its foliage. The supplied text cuts off before completing the replanting directions, so it does not support further specifics about that step.
The recommendations are attributed to the Homes & Gardens report. The source material contains no interviews or direct quotations from named gardening experts, and the instructions should be understood as the publication’s gardening advice rather than independently verified findings.

Advice and Missing Plant Details
The supplied article excerpt does not identify the other three plants in its promised list or provide the complete instructions for bleeding heart. It is also unclear whether the four-week frost guideline is based on a particular climate zone or whether the publication offers exceptions for different local conditions.
The report gives no trial data, measured bloom comparisons or success rates for plants divided in October. Its statements about rejuvenation, flowering and disease susceptibility are gardening guidance from the publication, not quantified outcomes. Gardeners should also check the needs of their specific varieties and local conditions before dividing.

Check Frost Dates Before Dividing
Gardeners considering the work should first estimate when the ground may freeze locally and proceed only if there are at least four weeks for establishment. They can then inspect mature clumps for crowding or reduced flowering and follow the report’s instructions for the relevant plant, including preserving healthy roots and shoots and watering new divisions.
The source material does not announce a follow-up test or additional reporting. The remaining three plants and the complete bleeding-heart directions would require consulting the full Homes & Gardens article; no further details are confirmed in the supplied text.

Key Questions
Why divide perennials in October?
The Homes & Gardens report says division can rejuvenate older clumps, manage plants that have become too large and provide new plants for other areas. It describes warm soil and moisture as favorable conditions, but results are not guaranteed.
How long should plants have before the first ground frost?
The report recommends allowing at least four weeks between transplanting divisions and the first ground frost. It does not give location-specific frost dates.
Which perennials are covered in the supplied report?
The provided text gives instructions for bee balm, phlox, coneflower and bleeding heart. It says the list contains seven plants, but the other three are not named in the supplied excerpt.
How should phlox divisions be protected over winter?
The report recommends adding a thick layer of mulch after fall planting. It says this can help reduce frost heave, which may lift plants as soil freezes and thaws.
Does the report prove dividing will increase blooms?
No measured results or success rates are included in the supplied material. The publication recommends division to help keep clumps vigorous and flowering, but it does not quantify an increase in blooms.
