A Homes & Gardens report advises gardeners to leave seven plants uncut in October and prune them in spring instead. The plants are sedum, ornamental grasses, coneflowers, lilyturf, plus three plants not identified in the supplied source excerpt; expert guidance says stems and seed heads can provide winter shelter and food, while foliage may help protect crowns from cold.
A Homes & Gardens report advises gardeners to leave several perennials standing in October rather than cutting them back before winter, saying their stems and seed heads can provide wildlife food and shelter and help shield plant crowns from cold. The supplied excerpt names sedum, ornamental grasses, coneflowers and lilyturf; it refers to seven plants overall but does not identify the other three in the material provided.
Horticulture expert Shannon Barnette of The Dawes Arboretum recommends delaying garden cleanup until spring temperatures have stayed above 50 degrees for a week. She says the wait gives overwintering pollinators time to emerge from places where they have sheltered. Barnette also says leaving plant material in place can protect crowns from harsh winter temperatures and late spring frosts that may harm new growth.
For sedum, Barnette says little winter preparation is needed in USDA hardiness zones 3–9, and cautions against mulch because trapped moisture may rot the crown and roots. Landscape designer Lee Miller recommends leaving ornamental grasses standing, then cutting them back in late March or early April after frost risk has passed and before new growth begins. She says fall cutting can expose the center of a grass to freezing temperatures and snow.
Coneflower seed heads can feed birds such as goldfinches, chickadees and juncos, while hollow stems can shelter overwintering pollinators, according to the report. Miller also advises leaving lilyturf, or Liriope, intact through winter and pruning in early spring when new growth appears. At that point, she says it can be cut to about one or two inches above the ground.
Winter Cover for Plants and Wildlife
Leaving stems and seed heads in place can serve two purposes: they may provide food and shelter for wildlife, and the remaining foliage can help protect a plant’s crown from winter exposure. The advice counters the common impulse to clear every faded stem during an October tidy-up, but it does not mean all fall pruning is harmful. The report says October remains a useful time for other garden tasks and frames the recommendation around particular perennials.
The timing matters because pruning too early may remove habitat before pollinators have emerged, while exposing crowns to cold or frost damage. The guidance also varies by plant: sedum is described as needing little winter preparation, whereas potted coneflowers may benefit from a sheltered location or burlap protection in colder conditions. Gardeners should account for local frost risk and plant-specific needs rather than applying a single schedule across the yard.

How the Spring Pruning Advice Works
The report focuses on the tension between a neat fall garden and the value of leaving some dead or faded growth in place. Its experts describe stems as potential overwintering habitat and seed heads as a winter food source for birds. For some plants, standing foliage also provides cover over the crown, the area where stems meet roots and new growth begins.
The named plants do not all share the same care instructions. Miller’s suggested late-March or early-April cutback for ornamental grasses is a seasonal example, not a universal date; she ties it to the end of frost danger and the start of new growth. For lilyturf, she likewise says to wait for early spring growth. Barnette gives a temperature-based cue for general spring cleanup: wait until temperatures have been above 50 degrees for a week. These are expert recommendations reported by Homes & Gardens, not a guarantee that the same calendar dates fit every region.
“My practice is to hold off on any spring clean-up and plant cutbacks until spring temperatures have been above 50 degrees for a week.”
— Shannon Barnette, horticulture expert at The Dawes Arboretum
Three Plants Missing From the Excerpt
The supplied source material says the report covers seven plants, but the excerpt provided identifies only four: sedum, ornamental grasses, coneflowers and lilyturf. It does not establish the identities or care recommendations for the remaining three, so they cannot be named here. The excerpt also does not give a publication date or specify a region for the advice. Exact pruning timing depends on local weather, frost conditions and the plant variety; the expert guidance should not be read as a single date suitable for every garden.
Wait for Local Spring Conditions
For the four plants named in the excerpt, gardeners can leave the foliage and seed heads standing through winter, then check plants as temperatures rise and new growth appears. Miller suggests cutting ornamental grasses in late March or early April once frost risk has passed, and pruning lilyturf in early spring after growth starts. Barnette’s broader cue is to wait for a week of spring temperatures above 50 degrees before cleanup. Local conditions and plant-specific requirements should guide the final timing; the supplied report excerpt offers no further details about the other three plants.
Key Questions
Which plants does the supplied report excerpt name?
It names sedum, ornamental grasses, coneflowers and lilyturf, also called monkey grass or Liriope. Although the report title refers to seven plants, the supplied excerpt does not identify the other three.
When should ornamental grasses be cut back?
Landscape designer Lee Miller recommends cutting them in late March or early April, after the threat of frost has passed and before new growth appears. The timing may vary with local weather.
Why leave coneflower stems standing?
The report says coneflower seed heads can provide food for birds, including goldfinches, chickadees and juncos, while hollow stems may provide winter shelter for pollinators.
Should sedum be mulched for winter?
Barnette says sedum generally needs little winter preparation in USDA zones 3–9 and advises against mulching it, because excess moisture trapped around the plant may rot its crown and roots.
Is it safe to leave every perennial uncut in fall?
No. The report’s advice applies to particular plants, and it says October pruning remains appropriate for some garden tasks. Check the needs of each plant and account for local frost and growing conditions.
