Winterize Your Garden

The Essential End-of-Season Checklist

As the growing season winds down, now is the ideal time to prepare your garden for the colder months ahead. A thoughtful wrap-up now means a healthier, easier start in spring. Here’s your friendly guide to finishing strong and protecting your outdoor spaces until warmer days return.

Clean up the beds

Start by removing spent annuals and any diseased or dying foliage. Leaving debris around can invite pests and disease to overwinter. After clearing the beds, spread a 2–3” layer of compost or mulch to insulate the soil, suppress weeds, and feed your plants during dormancy. Choose a high-quality organic compost and a mulch suitable for your climate.

Cut back and divide perennials

For hardy perennials, trim stems to a few inches above the ground, unless you’re leaving ornamental seed heads for winter interest or wildlife. Fall is the perfect time to divide overcrowded clumps of plants like hostas or daylilies—this ensures stronger plants and better blooming next year.

Protect shrubs, trees and tender plants

Young trees and shrubs, as well as tender evergreens, benefit from insulation. Wrap vulnerable plants in burlap to shield them from harsh winds and snow. Having a layer of mulch around the base helps keep roots protected from temperature swings.

Drain and store your tools and irrigation gear

Disconnect garden hoses before freezing temperatures hit, drain them thoroughly and store them indoors to avoid cracking. Clean and oil your hand tools so they remain rust-free and ready for spring. For sprinklers and other equipment, move into a dry, frost-free area.

Prepare pots and containers

Terracotta and ceramic containers are especially vulnerable to cracking in frost. Empty them, clean them well, and store them in a sheltered place. For heavy containers that can’t move, wrap them in burlap or bubble wrap to lessen the freeze-thaw strain.

Feed and protect your lawn

If you have a lawn area, now is the time to rake up leaves, remove thatch and apply a late-season fertilizer. A slow-release formula designed for fall strengthens roots and helps the lawn recover quickly in spring.

This comprehensive checklist helps ensure you’re covering all the bases—soil, plants, containers, tools—so your garden rests well and shows up strong when the next season begins. Be sure to stock up on key supplies like compost, mulch and burlap now before the winter rush.
