28 Fall Gardening Tasks to Prepare Your Garden for Winter

Now that the leaves are dropping and the flowers are fading, what’s next for the garden? Quite a bit, as it turns out. Here’s my fall task list for getting the garden ready for winter.

When I was a new gardener, the end of summer felt bittersweet: I was sad to watch the flowers fade, but I also looked forward to a break from the long hours in the garden. What I didn’t realize back then was that the work wasn’t quite over.

Preparing a garden for winter is some of the most valuable work you do all year. Every task on this list is really you setting next season up to thrive. Here are 28 ways to do it.

Cleaning and Clearing Out the Garden

1. Cut Back Infested and Diseased Plants

Cut back perennials that are done blooming and are diseased or pest-infested. Diseased plants can spread to healthy ones, so removing the dead or dying foliage helps stop fungal growth, infestations, and disease before they take hold.

You can leave many of the healthy spent perennials to break down over winter, which adds nutrients back to the soil, protects it, and reduces erosion, as long as there’s no sign of disease, pests, or fungus. Many seed heads are worth leaving too, since they feed the birds through the cold months.

2. Remove Weeds

Keep weeds to a minimum through fall and pull any invasive ones from the beds now, so they don’t get a head start next spring.

3. Clear Debris and Fallen Leaves

Deadhead spent flowers and clear out debris like faded blooms, fallen branches, and spent annuals. It removes the spots where insects and diseases overwinter. Rake up and remove fallen leaves from the beds and lawn. Hang onto them, though. They make excellent mulch and leaf mold.

4. Divide and Transplant Perennials

Before the ground freezes, divide any mature perennials that are starting to crowd their space. Move the divisions elsewhere in the garden or share them with friends and neighbors.

5. Clean and Store Garden Tools

This is the time to sterilize seed trays, plastic markers, tomato cages, and hand tools by soaking them in a water-bleach solution. Let everything air-dry, then store it in the garage, shed, or greenhouse for winter. Sterilizing cuts down on mineral buildup and keeps you from spreading fungus and bacteria to next year’s plants when you reuse those tools and pots.

Soil Care

6. Test and Analyze Your Soil

Check your soil now to understand the shape it’s in. A soil test tells you your pH and nutrient levels, which takes the guesswork out of fertilizing and amending next season. Amendments like compost, manure, straw, or well-rotted leaves enrich the soil, hold moisture, improve structure, and add the nutrients your plants will need.

7. Add Organic Matter

Work organic matter into your soil. Use anything with carbon compounds made by living organisms such as lawn clippings, leaves, stems, branches, moss, even the insects, earthworms, and microbes already at work in the bed. It feeds the soil and encourages beneficial organisms to thrive.

8. Mulch to Protect Roots

A3-inch layer of mulch on your beds is one of the most important fall jobs and…

And don’t forget your fallen leaves make great mulch, with many of the same benefits and none of the cost.

9. Sow a Cover Crop

Instead of leaving soil bare all winter, plant a cover crop like clover or rye. These hold the soil in place, prevent erosion, and keep nutrients from leaching away. Come spring, turn them under and they enrich the bed with everything they stored.

Protect Your Plants

10. Dig Up Tender Bulbs and Tubers

In zones 7 and below, dahlia tubers and other tender bulbs won’t survive winter in the ground. There, dig them up soon after the foliage browns and store them somewhere cool and dry through the cold months.

I’m in Zone 8b with much milder winters, so I leave my tubers and bulbs in the ground and add a few inches of mulch around each plant to protect them from freezing temperatures and heavy snow.

11. Overwinter Tender Plants

Tender plants can be damaged or killed by frost, so they need protecting. A few examples:

One of my own fall jobs is overwintering my geraniums in the greenhouse. No greenhouse? No worries. Check out my tips on the other methods of overwintering geraniums in my blog post.

Winterize the Garden

12. Store Garden Items

Bring furniture, accessories, structures, and equipment in before the freezing temperatures arrive:

13. Insulate Cold Frames and Greenhouses

Insulation like bubble wrap, row covers, or blankets traps heat and keeps frost out. That extra layer can make the difference for anything you’re trying to carry through the cold season.

Pest and Disease Control

We all get pests, but there’s no need to reach for harsh chemicals. Here are a few natural, organic ways to keep pests in check through winter.

14. Remove Potential Pest Habitats

Fallen leaves, garden debris, and old plant material all make cozy winter hideouts for pests. Clearing those spots out now lowers your odds of an infestation come spring.

15. Apply Dormant Oils or Natural Repellents

Dormant oils, sprayed on trees and shrubs during their dormant season, smother overwintering insects and their eggs. Natural repellents like neem oil or garlic spray work too. These eco-friendly options help keep the garden healthy through winter without the harsh stuff.

16. Inspect Plants for Disease

Watch for discolored leaves, spots, or odd growth. Catching problems now keeps them from spreading and becoming a bigger headache in spring. Where you find trouble, prune the affected parts, and lean on disease-resistant varieties when you replant.

Harvest and Compost

17. Harvest Your Flowers

Harvesting before winter sets in means you don’t lose blooms to frost or pests, and you get to enjoy them indoors.

18. Compost Garden Waste

Collecting fallen leaves and garden waste in a compost pile or bin turns it into a real resource. As it breaks down, it becomes nutrient-rich compost to improve your soil come spring, cutting waste and building fertility at the same time. Remember your greens and browns: green materials (fresh leaves, grass clippings, manure) are higher in nitrogen and break down faster.

Watering and Irrigation

As winter approaches, good water management protects plants and prevents damage. Preparing for freezes, watching moisture levels, and mulching all help keep things safe through the season.

19. Adjust Your Watering

With cooler temperatures and shorter days, plants need less water, so scale back your watering routine. Overwatering can cause root rot and other problems. Watch the weather, the soil, and what each plant needs, then adjust accordingly.

20. Mulch Around Plants

A layer of organic material like straw, wood chips, or leaves insulates the soil and keeps it from freezing too fast. It holds warmth and moisture, acts like a protective blanket over the roots, reduces plant stress, and guards against erosion from winter rain and melting snow.

21. Drain and Store Hoses

Water freezing inside a hose can crack it and ruin it. Before the chill sets in, disconnect your hoses, drain them fully, and coil them up for storage.

22. Protect Water Features from Freezing

Fountains, ponds, and birdbaths can freeze and crack as temperatures drop. A floating de-icer or submersible heater keeps the water from freezing solid.

Winter Planting

23. Plant Spring Bulbs

As the season winds down, it’s the perfect time to set up spring. Plant spring bulbs like tulips, daffodils, and crocus before the first hard freeze, and they’ll rest underground until they surprise you in the spring.

24. Plant Trees and Shrubs

Fall is ideal for planting trees and shrubs. The soil is still warm enough for roots to establish if you plant well before the first frost, which gives them time to settle in before the cold.

25. Sow Cover Crops

Cover crops like clover, rye, or winter wheat, planted in fall, shield your beds from the harshest winter weather. Turned under in spring, they prevent erosion, suppress weeds, and build soil health with added organic matter.

Garden Journaling

Keeping a detailed record in a garden journal or planner makes it easy to note what worked, what didn’t, and what you want to change next year.

26. Document Your Garden’s Current State

Before winter arrives, capture where the garden stands, with photos or a few written notes. It helps you plan improvements, track growth, and spot the problems we’re solving when spring comes around.

27. Note the Season’s Wins and Losses

Take a moment to reflect. Did a pest problem crop up that will need addressing next year? Did you try a new flower variety you loved? Write it down while it’s fresh. You will be grateful you did. I promise.

28. Make a Winter Maintenance Schedule

Set up a simple winter schedule. Check for damage after heavy snow and inspect your overwintering plants. Planning ahead lets you handle winter garden care without feeling buried by it.
