Gardening Know How recommends dividing suitable established perennials in October, when soil is still workable and new sections may have time to root before the first frost. Its guide describes methods for seven plants in the supplied material; the headline promises eight, but the eighth plant’s details are missing from the source excerpt.
Gardening Know How recommends October division for established perennials that need thinning or can be propagated from their roots, saying the soil is generally still workable and sections can establish before the first frost. The supplied report gives instructions for seven plants, although its headline advertises eight; the eighth plant’s name and directions are not included in the material provided.
Division means lifting a mature perennial and splitting its root system into two or more rooted sections for replanting. The guide says the method applies to perennials, not annuals, and advises avoiding the heat of summer and the middle of winter. It identifies early spring as another suitable period, alongside October.
For the listed plants, the steps vary. The report advises separating hosta clumps; dividing sedum after flowering and retaining roots and healthy stems; and giving each peony section at least three eyes—the pink buds at the crown—along with strong roots. Peony eyes should be no more than 2 inches (5 centimeters) below the soil surface after replanting.
For bearded iris, the guide says to trim foliage to about 6 inches (15 centimeters), divide the clump, let it dry for a day and replant with the rhizome tops at soil level. It also describes dividing astilbe with a sharp spade, keeping three shoots or growing buds on each bee balm section, and removing bee balm’s woody or dead center. The excerpt ends during its bleeding-heart entry, so it does not provide that plant’s full instructions.
October Division Can Stretch Garden Stock
Division can give gardeners additional plants from an established clump while also reducing its size. That makes the practice useful when a perennial has outgrown its space or when a gardener wants to fill another bed without buying more plants. The source describes this as a way to propagate plants, but gives no cost estimates or measured success rates.
The timing advice matters because newly separated roots need time to settle in before freezing conditions. The report recommends replanting divisions promptly and keeping the surrounding soil moist for several weeks. These are general recommendations in the article, not a guarantee that every division will establish before frost in every location.

The Guide’s Seven Plant Instructions
The report’s central method is to dig around the plant with a sharp spade or garden fork, lift the root ball, and separate it with a sharp tool or by hand where practical. It says each section should be replanted immediately at its previous depth, with soil pressed around the roots to remove air pockets, followed by thorough watering.
Before dividing, the guide recommends watering the soil around the plant several days ahead. After replanting, it advises keeping soil consistently moist for several weeks while roots re-establish. The named plants in the supplied excerpt are hostas, sedum, peonies, bearded iris, astilbe, bee balm and bleeding heart; only the first six have usable plant-specific directions in the provided text, with the bleeding-heart entry cut off.
““Along with early spring, October is one of the very best times to propagate your perennials by division.””

The Eighth Plant Is Not Listed
The supplied source excerpt does not identify the eighth perennial promised by the headline, and it ends partway through the bleeding-heart section. It is therefore unclear whether bleeding heart is the eighth plant or whether another entry followed it in the original article. The source also gives no geographic zone, local frost date or weather conditions, so the appropriate timing may vary by garden.
The report offers practical guidance but does not cite trial data or quantify how often divisions survive. Its recommendations should not be read as a guarantee of establishment. Readers also need to check the needs of each plant and local conditions before dividing.

Replant Before Local Frost
Gardeners following the report should check local frost forecasts, select suitable established perennials and have planting locations ready before lifting them. The guide’s sequence is to water in advance, divide with clean, sharp tools, replant promptly at the original depth and water thoroughly. Keep soil moist for several weeks, adjusting watering to rainfall and site conditions.
The supplied material does not state whether Gardening Know How will publish a correction or provide the missing eighth entry. Until that detail is available, the article supports specific directions for the plants listed above, but not a complete eight-plant list.

Key Questions
Which perennials does the supplied guide identify for October division?
It names hostas, sedum, peonies, bearded iris, astilbe, bee balm and bleeding heart. The excerpt does not provide complete directions for bleeding heart or identify a separate eighth plant.
Why does the report recommend October?
The report says the soil is still workable and divisions may have time to establish roots before the first frost. It also lists early spring as a suitable time and advises avoiding summer heat and the middle of winter.
How should a newly divided perennial be replanted?
The guide recommends replanting each section promptly at the depth where the original plant grew, firming soil around the roots and watering thoroughly. Keep the soil consistently moist for several weeks while the roots re-establish.
Does the source provide instructions for all eight plants in its headline?
No. The supplied excerpt contains plant-specific directions for six plants and begins a bleeding-heart entry before cutting off. It does not show the eighth plant or a complete set of eight instructions.
