Fall Cleanup to Prepare for Winter Garden Interest

Nature Hills Nursery | February 14, 2026

Before your fire up your weed eaters and trimmers and rampage through your yard cutting down and removing everything in sight this fall, stop! Take a step back. It’s time to reconsider your winter clean up protocol.

Let’s take a look and change your perspective to see your winter landscape in a new way. You don’t need to cut everything down. Do you have any perennials or other plants that may offer winter interest if you left them untrimmed until after winter?

What Does Your Landscape Look Like in Winter?

Evergreens, ornamental grasses and hydrangeas definitely offer winter interest. Perennials can also add interest to the winter landscape, so don’t be too quick to cut them down. Study shapes, colors and form.

Not all dormant regions get dumped with snow. Some regions have lighter snowfalls that can highlight and sculpt the snow, creating something pretty to look at on those cold winter days.

Do you have plants with berries or seed heads that remain on the plants? They not only look great but provide food for birds and other wildlife. Leaving last year’s growth also gives songbirds a place to snuggle in for some protection from the cold and wind.

The tops of the perennials catch the snow to insulate the ground over the top of the plants. Leaving some of your natives and perennials up for the winter gives the beneficial insects a place to overwinter.

If you simply cut your perennial garden down to the ground in fall, you don’t have much to look at, no way to catch the blowing snow, no cover for songbirds and wildlife, no place for beneficial insects, and no seed heads left to feed the birds.

Vegetable Plants, Annuals and Peonies Should Be Removed

Did you know viruses can overwinter on the leaves and stems of vegetables and annual plants that only live a single season? For veggies and annuals plants, dig up and remove the entire plant to lessen the risk of disease and improve sanitation. Compost them or put them in your Yard Waste containers.

One perennial that does need to be trimmed down early fall of each year are Peonies. Peonies can get mildew and botrytis. Cut every Peony stem to the ground and bag them up for removal. This can eliminate the carryover of the problems that might re-infect the plants the following spring.

Also remove any perennials that had leaf spotting, mildew or disease problems of any kind. Cut them down to the ground after the frost has killed off the tops of the plants, bag them up and remove them from your yard for best sanitation practices. Remember, you don’t have to cut all of your perennials down to the ground each fall, just any one that showed some problems this past growing season.

Rose Care in Autumn

It is very important to leave your rose bushes untrimmed for the winter months. Do not cut your roses until spring!

Rose bushes left untrimmed may have rose hips that are showy all winter long and if not, the branches will catch the snow and add insulation to your rose plant. Roses love to have additional insulation in colder regions

The old fashioned method of overwintering roses was to cover them with rose cones. Today the easiest method is to pile on a mound of shredded hardwood mulch about a foot high directly on the stems of the plants.

In spring pull the mulch away and THEN cut them in the spring. Using this method, if there was some winter damage, you will cut and remove it.

Flowering Shrub Care in Autumn

Know the best time to prune your shrubs. Don’t trim the plants which bloom on last .

Do not trim these shrubs in the fall: Flowering Quince, Forsythia, Rhododendrons & Azaleas, Prunus family, Weigela, all Lilacs and Magnolias. Wait until after they bloom in spring. Wait to trim until after the flowers fade.

A Better Way to Handle Leaves in Fall

Remember how we used to bag leaves them up and put them in the trash? What a chore that was! There is a better way.

Leaves on the grass should be mowed over, shredding them so they don’t mat and cover the grass. Keep mowing your grass until the leaves are chewed up and shredded. Compost them after shredding or used them as mulch around your garden. Put those leaves to good use!

Watering in Fall

Lastly, don’t forget to keep giving all of your newly planted trees and shrubs a good drink of water right up until they go dormant. Evergreens give off water all winter long so if you are in an area where the ground freezes up, be sure to water the roots well until the ground does freeze for best results.

Following the tips listed above should assist you preparing your yard for a restful winter season, ready and waiting for you in the spring. Enjoy your winter garden!

Frequently Asked Questions

How do I winterize my garden beds and borders before the first hard freeze?

Before the first hard freeze, resist the urge to cut everything down, as ornamental grasses, hydrangeas, and perennials with seed heads provide winter interest, shelter for songbirds, habitat for beneficial insects, and insulation for plant roots. However, there are important exceptions: dig up and remove all vegetable plants and annuals entirely to prevent disease from overwintering on their stems and leaves, and cut peonies all the way to the ground, bagging the trimmings for disposal rather than composting them. Any perennials that showed signs of leaf spotting, mildew, or disease should also be cut to the ground and removed from your yard after frost kills the foliage. Leave healthy perennials and natives standing through winter, then plan your full cleanup for late winter or early spring before new growth emerges.

Can I leave fallen leaves in my flower beds over winter, or do they need to be raked out?

Fallen leaves can actually serve as a beneficial natural mulch in flower beds over winter, helping to insulate the soil and protect plant roots from freeze-thaw cycles. However, thick mats of wet leaves can smother plants and create conditions that harbor disease, so moderation is key. A light layer is generally fine to leave in place, but if you have diseased plants in the bed, remove those leaves entirely rather than letting them decompose in place. Aim to either rake out dense accumulations or shred them with a mower first so they break down more easily without clumping.

Which plants should be removed completely during fall cleanup because of disease or pest problems?

Vegetable plants, annuals, and peonies should be fully removed during fall cleanup due to their potential to harbor disease over winter. Viruses can overwinter on the leaves and stems of vegetables and annuals, so dig up and remove the entire plant to reduce disease risk. Peonies are especially prone to mildew and botrytis, so cut every stem to the ground after frost and bag them for removal rather than composting. Any perennial that showed signs of leaf spotting, mildew, or disease during the growing season should receive the same treatment to prevent reinfection the following spring.

Is it better to pull spent annuals and finished vegetable plants right after frost or wait until later in fall?

It is best to remove spent annuals and finished vegetable plants promptly after frost kills them off rather than leaving them to sit through the season. Viruses and diseases can overwinter on the leaves and stems of these plants, increasing the risk of reinfection the following year. Dig up the entire plant, roots and all, and either compost them or place them in yard waste containers for removal. Do not let diseased material linger in your garden beds once the growing season has ended.

Should I apply mulch before or after cutting back plants in the fall?

Apply mulch after you've completed your fall cleanup and after the ground has experienced a hard frost, typically when temperatures consistently drop below 32°F. For most plants you're leaving standing for winter interest, add 2 to 3 inches of mulch around the base to insulate roots without smothering crowns. For perennials, annuals, and vegetables you've removed entirely, mulching the bare soil helps regulate soil temperature and reduce erosion over winter. Focus your mulching efforts in late fall, once the ground has begun to cool but before it freezes solid.

Is it safe to compost fall garden debris, or should some material go in the trash instead?

Not all fall garden debris is safe to compost. Vegetable plants, annuals, peonies, and any perennials that showed signs of leaf spotting, mildew, or disease during the season should be bagged and sent to yard waste or trash, since viruses and fungal spores can overwinter on plant material and reinfect your garden the following spring. Healthy perennial trimmings and general garden debris are fine candidates for the compost pile. When in doubt, if a plant showed any disease symptoms, bag it and remove it from your property entirely.

Should I plant a cover crop in empty vegetable beds to protect the soil over winter?

Cover crops like winter rye, crimson clover, or hairy vetch are an excellent way to protect bare vegetable beds over winter, preventing erosion and improving soil structure. Sow them in late summer to early fall, typically 4 to 6 weeks before your first expected frost, so they have time to establish before cold sets in. In colder zones (4 and below), opt for hardy varieties like winter rye that can survive harsh conditions. Till the crop into the soil in early spring before it goes to seed to add valuable organic matter and nutrients ahead of your next planting season.

How do I protect shrubs, young trees, and evergreens from winter damage caused by deer, rabbits, and wind?

While this article focuses on fall cleanup and winter interest, protecting woody plants from animal and wind damage is an important part of winter prep. Wrap young tree trunks with plastic spiral guards or hardware cloth cylinders extending at least 4 feet high to deter deer and rabbits, installing them in late fall before the first hard freeze. For evergreens prone to windburn and heavy snow damage, apply an anti-desiccant spray like Wilt-Pruf in late November and again in January, and use burlap screens on the windward side of vulnerable plants.

Should I clean up ornamental grasses in fall or leave them standing for winter interest?

Ornamental grasses are excellent candidates for leaving standing through winter, as they provide visual interest, catch and sculpt snow beautifully, offer shelter for songbirds, and create overwintering habitat for beneficial insects. Unlike diseased perennials or annuals, healthy ornamental grasses pose no sanitation concerns that would require fall removal. Wait until late winter or very early spring to cut them back before new growth emerges, giving you maximum seasonal interest and wildlife benefit throughout the cold months.

What is the best way to deal with weeds during fall cleanup so they do not come back next year?

While the fall cleanup article does not specifically address weed control, the best general practice is to remove weeds before they go to seed, as many common weeds can drop hundreds of seeds that will germinate the following spring. Pull or dig weeds by the root rather than cutting them down, since many perennial weeds will regrow from root fragments left in the soil. Bag up any weeds with seed heads and place them in yard waste containers rather than composting them, as home compost piles often do not reach temperatures high enough to kill weed seeds. Focus your weed removal efforts in early to mid-fall before the first hard frost so you can clearly identify and thoroughly remove the plants while the soil is still workable.
