What Your Garden Needs Before Winter
By November, most St. Louis gardens look like they’re winding down. The mums are fading, the oaks are finally dropping their leaves, and the first hard frosts have usually arrived. It’s tempting to call the season done.
But November is one of the most important months of the year for your landscape. What you do now decides how your beds look in April, how well your roses come through winter, and whether your tulips actually show up in spring.
Here’s what our team at Quiet Village focuses on in November, and how you can do the same at home.
1. Finish Your Fall Cleanup (Without Stripping Everything Bare)
A good fall cleanup in St. Louis isn’t about making beds look empty. It’s about removing what can cause problems and leaving what helps.
Focus on:
- Pulling weeds before they settle in for winter. Henbit and chickweed sprout in fall and come back strong in spring if you leave them.
- Removing diseased plant material. If a plant struggled with powdery mildew or leaf spot this summer, cut it back and bag the debris. Don’t compost it or leave it in the bed, where fungus can overwinter.
- Tidying bed edges along walkways and lawn lines so everything looks clean through the gray months.
The goal is a garden that looks cared for, not scraped clean.
2. Plant Spring Bulbs: It’s Not Too Late for Tulips
If you’ve been wondering when to plant tulip bulbs in St. Louis, November is the sweet spot. The soil has cooled enough that bulbs focus on growing roots instead of sprouting early, and squirrels have usually finished their busiest digging season.
Tulips can go in the ground right up until it freezes. A few tips for getting it right:
- Plant deep. Tulips and daffodils do best around 7 to 8 inches down. Smaller bulbs like crocus only need 3 to 4 inches.
- Plant in groups. Clusters of bulbs look natural and full. Single rows of tulips tend to look stiff.
- Mind the drainage. St. Louis clay holds water, and bulbs rot in soggy soil. Avoid low spots where water sits, or work in compost to loosen the soil.
- Water once, then mulch. A good soak after planting helps roots get started. Then add a couple inches of shredded mulch on top.
Planting under trees that lose their leaves works well too, since most bulbs bloom before the canopy fills in.
3. Cut Back the Right Perennials (and Leave the Rest Standing)
This is where most homeowners get stuck. Should you cut everything back in fall, or leave it all until spring? The answer is somewhere in between.
Perennials to cut back in November
- Hostas. Their collapsed leaves become a cozy winter home for slugs.
- Daylilies and irises. Iris foliage in particular can shelter borer eggs that hatch in spring.
- Peonies. Cutting them back helps prevent disease next year.
- Anything that had mildew or disease this season.
When you cut back, leave about 2 inches of stem above the soil. That protects the crown and helps you find the plant again in spring.
Perennials to leave standing
Native plants and perennials with seed heads can stay up all winter. Coneflowers, black-eyed Susans, sedum, and other natives feed birds through the cold months, and their hollow stems give native bees and beneficial insects a place to overwinter.
Ornamental grasses should stay up too. They add movement and structure to the winter landscape, and we wait until late winter to cut them back.
A mix of both gives you a garden that looks intentional and still supports the wildlife that helps it thrive.
4. Mulch Around Roses and Boxwoods
November is the month to give your roses and boxwoods extra protection before the coldest weather hits.
- Roses: Once you’ve had a hard frost, mound a heavy layer of mulch around the base of each plant. This insulates the crown through St. Louis freeze-thaw cycles. Hold off on pruning roses now. Heavy cuts this late can encourage tender new growth that won’t survive winter. We save rose pruning for late winter.
- Boxwoods: Add a generous layer of mulch over the root zone. Boxwoods have shallow roots and appreciate the insulation. Avoid heavy trimming this time of year.
For both, keep mulch pulled back slightly from stems and trunks. Mulch piled right against the bark holds moisture and invites rot and pests.
5. Keep Up With Leaves
Leaf cleanup is the job that defines November in St. Louis. Neighborhoods like Kirkwood, Webster, Frontenac, and Town and Country have beautiful mature trees, and that means leaves keep coming well into December.
A few things to know:
- Get leaves off the lawn. A thick layer left on your grass blocks light and can leave dead patches you’ll be fixing in spring.
- Some leaves in beds are fine. A light layer in planting beds works like natural mulch and protects soil. Just don’t let them pile up thick around stems or smother low plants.
- Plan for more than one round. One cleanup rarely does it here. Many homeowners schedule a pass around Halloween, another around Thanksgiving, and a final one before Christmas.
A Few Things to Hold Off On in November
Knowing what not to do matters just as much:
- Don’t heavily prune shrubs. Hard pruning now can trigger new growth that gets damaged by cold.
- Don’t cut back ornamental grasses yet.
- Don’t prune spring-flowering shrubs like lilacs, forsythia, or azaleas. You’d be cutting off next spring’s blooms.
- Don’t forget to water. If November turns dry, keep watering evergreens and anything newly planted until the ground freezes. Evergreens lose moisture all winter and go in stronger when they’re well hydrated.
Your November Garden Checklist
- Weed beds and remove diseased plant material
- Edge beds, walkways, and lawn lines
- Plant tulips and other spring bulbs before the ground freezes
- Cut back hostas, daylilies, irises, and peonies to about 2 inches
- Leave native perennials and ornamental grasses standing
- Mulch heavily around roses and boxwood root zones
- Clear leaves from the lawn, with a light layer allowed in beds
- Water evergreens and new plantings during dry spells
