A Homes & Gardens report recommends delaying October cutbacks for seven plants, including sedum, ornamental grasses, coneflowers and lilyturf. Garden experts cited in the report say standing stems and seed heads can shelter wildlife and help protect plants from cold; the best timing depends on the plant and local frost conditions.
A Homes & Gardens report advises gardeners to leave seven plants standing through October rather than cut them back before winter, citing benefits for overwintering wildlife and protection from cold, as explained in this guide to October pruning. The listed plants are sedum, ornamental grasses, coneflowers, lilyturf, and three additional plants named in the report’s full list; the supplied source text gives details for only the first four.
The report’s advice comes from Shannon Barnette, horticulture manager at The Dawes Arboretum, and Lee Miller, a garden designer and consultant. They describe different reasons to delay pruning: seed heads can feed birds, hollow stems can shelter pollinators, and standing foliage may help shield plant crowns from freezing temperatures. These are expert recommendations, not a rule that every garden plant should be left untouched.
For sedum, Barnette recommends waiting because the remaining growth can protect the crown through winter and late spring frosts. She says sedum is hardy in USDA zones 3–9 and cautions against mulching it, since excess moisture around the crown and roots can contribute to rot. The report does not specify whether this applies equally to every sedum variety or garden setting.
Ornamental grasses can be cut in late March or early April, Miller says, once frost risk has passed and before new growth emerges. Leaving the clumps standing also adds winter structure to a garden. For coneflowers, Barnette points to seed heads eaten by birds such as goldfinches, chickadees and juncos, as well as hollow stems that can provide pollinator habitat. Miller recommends leaving lilyturf, also called liriope or monkey grass, intact over winter and trimming it in early spring when new growth appears, to about one or two inches above the ground.
Winter Cover Helps Plants and Wildlife
Delaying a fall cleanup can preserve resources that disappear when stems and seed heads are removed. The report identifies food for birds and shelter for pollinators as reasons to leave some plants standing. It also says that cutting foliage too early can expose crowns and roots to cold, potentially harming plants. That matters to gardeners weighing a tidy autumn appearance against winter habitat and plant protection.
The recommendations are plant-specific: the report explicitly warns that sedum should not be mulched, while noting that some ornamental grasses may benefit from light mulch. Gardeners should not apply one winter-care method to every perennial. Local climate, the plant variety and drainage conditions all affect what is appropriate.

The Report’s Four Detailed Plant Picks
The article is a seasonal gardening report built around advice from two named professionals. Its central distinction is between plants that can be cut back for fall maintenance and plants whose stems or seed heads may serve a purpose through winter. Barnette gives a temperature-based approach to spring cleanup: she says she waits until spring temperatures have stayed above 50 degrees for a week, so overwintering pollinators have had an opportunity to emerge.
The supplied report text describes four plants in detail: sedum, ornamental grasses, coneflowers and lilyturf. Although the headline promises seven, the remaining three plant names and their associated advice are not included in the source material provided here. The article also notes hardiness ranges of USDA zones 3–9 for sedum and coneflower, but those ranges should not be taken as a guarantee for every cultivar or local growing condition.
“Cutting back ornamental grasses in fall can subject the center of the plant to freezing temperatures and snow, causing the crown to hollow out.”
— Lee Miller, garden designer and consultant
Three Plants Missing From Source
The supplied source excerpt identifies only four of the seven plants named in the headline. It does not provide the other three names or the advice attached to them, so they cannot be reported here without additional sourcing. The recommendations also do not establish a single pruning date for all regions: spring temperatures, frost risk, plant variety and local conditions differ. The source does not provide independent research or quantify how much wildlife or plant survival is affected by leaving stems standing.
Check Local Spring Conditions
For the plants covered in the source, the next step is to leave the listed foliage in place through winter and reassess when spring growth or warmer temperatures arrive. Miller places ornamental-grass pruning in late March or early April after frost threats pass and before new growth begins; for lilyturf, she advises waiting for the first signs of new growth. Barnette’s cleanup practice uses a week of spring temperatures above 50 degrees as a guide for pollinator emergence.
Gardeners should check the needs of their specific plants and local climate before pruning or adding mulch. Further reporting would be needed to identify the other three plants in the article’s advertised list and confirm the advice associated with them.
Key Questions
Which plants does the supplied report advise leaving uncut?
It gives detailed guidance for sedum, ornamental grasses, coneflowers and lilyturf. The three other plants promised by the headline are not named in the source text provided.
When should ornamental grasses be cut back?
Garden designer Lee Miller recommends late March or early April, after the threat of frost has passed and before new growth appears. Local conditions may change that timing.
Why leave coneflower seed heads over winter?
The report says coneflower seeds can feed birds, including goldfinches, chickadees and juncos. Its hollow stems may also provide winter shelter for pollinators, according to horticulture expert Shannon Barnette.
Should sedum be mulched for winter?
Barnette advises against mulching sedum because trapped excess moisture can contribute to crown and root rot. The report says sedum generally needs little winterizing, but care can vary by plant and garden conditions.
