A Homes & Gardens report, citing two gardening experts, recommends leaving seven plants uncut in October and pruning them in spring. Their standing stems and seed heads can shelter plants from winter conditions and provide food or habitat for wildlife; exact timing and care vary by plant and local climate.
A Homes & Gardens report advises gardeners to leave seven perennials and ornamental plants standing in October rather than cutting them back, saying their stems and seed heads can protect plants through winter and support wildlife. The recommendations come from horticulture expert Shannon Barnette and garden designer Lee Miller; they describe general guidance, not a rule for every plant or climate.
The plants named are sedum, ornamental grasses, coneflowers, lilyturf, rudbeckia, Russian sage and Joe Pye weed. The report says faded stems can shield plant crowns and roots from cold, while seed heads offer food to birds and hollow stems can provide winter habitat for pollinators. Which benefit applies depends on the plant.
Barnette, horticulture manager at The Dawes Arboretum, says she delays spring cleanup until spring temperatures have stayed above 50 degrees for a week, allowing overwintering pollinators time to emerge. She recommends leaving sedum standing to protect its crown. The report also cautions against mulching sedum, because excess moisture around its crown and roots can contribute to rot.
Miller advises leaving ornamental grasses intact over winter and cutting them back in late March or early April, after frost risk has passed and before new growth appears. For lilyturf, also called Liriope or monkey grass, she recommends waiting until spring growth begins, then cutting foliage to one or two inches above the ground. The report says gardeners should check the winter needs of their particular ornamental grass.
Winter Cover and Wildlife Food
Waiting to prune can serve two purposes: standing foliage may buffer crowns and roots from cold, and seed heads and hollow stems can remain useful to wildlife. The report specifically names goldfinches, chickadees and juncos as birds that feed on coneflower seeds, and says its stems can shelter overwintering pollinators.
That does not mean every garden should be left untouched. The guidance is about selected plants, and the report notes that some fall pruning is still appropriate for other garden tasks. Leaving the listed plants standing can also preserve winter texture, particularly in ornamental grasses, while avoiding premature removal of potential habitat.
For gardeners, the practical point is to identify plants before a broad fall cleanup. Plant-specific timing matters: sedum may be left without extra winterizing, while potted coneflowers in colder locations may benefit from a sheltered position or burlap around the pot, according to the report.

How Spring Pruning Timing Varies
The report does not say that October pruning is always harmful. It distinguishes plants that can benefit from keeping their faded growth through winter from other plants that may need fall attention. The seven recommendations draw on advice from Barnette and Miller, rather than a single universal pruning schedule.
Timing in spring is also not identical for every plant. Miller’s late-March or early-April window applies to ornamental grasses and may not suit every region. Her guidance for lilyturf is to wait for visible new growth. Barnette gives a temperature-based threshold for her own spring cleanup practice. These differences underline the need to account for local frost conditions and plant type.
“Holding off on cutting back can protect the crown of the plant from harsh winter temperatures, as well as late spring frosts that could damage new plant tissues.”
— Shannon Barnette
Local Conditions Change the Schedule
The report does not provide a single pruning date that applies across climates, nor does it detail care instructions for every cultivar of the seven plants. Frost dates, winter severity and plant variety can affect when spring pruning is appropriate. The article advises checking the needs of a specific ornamental grass, and its recommendations should not be read as a guarantee that leaving every listed plant untouched will prevent winter damage.
It also does not quantify the wildlife benefits or compare outcomes for plants pruned in fall versus spring. The advice is attributed to two experts and presented as practical gardening guidance; no study or trial data are cited in the supplied report.
Wait for Spring Growth Signals
For now, gardeners following this advice can leave the listed plants standing and monitor local weather. In spring, wait until frost risk has eased before cutting back ornamental grasses; for lilyturf, look for the first signs of new growth. Barnette’s stated practice is to wait until temperatures have remained above 50 degrees for a week before spring cleanup.
Before pruning, check instructions for the particular species and local conditions, especially for grasses and plants in pots. The report does not announce a new policy or scheduled follow-up; its next practical milestone is the return of suitable spring temperatures and new growth.
Key Questions
Which seven plants does the report recommend leaving uncut in October?
It names sedum, ornamental grasses, coneflowers, lilyturf, rudbeckia, Russian sage and Joe Pye weed.
Why leave coneflowers standing over winter?
The report says coneflower seed heads can feed birds, including goldfinches, chickadees and juncos, while hollow stems can provide shelter for overwintering pollinators.
When should ornamental grasses be cut back?
Designer Lee Miller recommends late March or early April, after frost risk has passed and before new growth appears. The best timing can vary by location and grass type.
When should lilyturf be pruned?
Miller advises waiting until early spring, when new growth first appears, then cutting the foliage to one or two inches above the ground.
Should sedum be mulched for winter?
The report says Barnette advises against mulching sedum because trapped excess moisture may contribute to rot around the crown and roots.
