Check these things off your to-do list soon so that an unexpected early hard frost or snowfall doesn’t catch you by surprise. Then, sit back and start dreaming about next year’s gardening to help you get through those darkest days of winter.
Replace tired-looking summer annuals with ornamental kale and grasses. Arrange pumpkins and gourds around the garden and home, and decorate lamp posts with dried cornstalks. Cut branches of cotoneaster and beautyberry to adorn your dining room table for festive harvest dinners, or stick the branches into year-round outdoor containers for extra seasonal colour.
Extend the season
If your garden doesn’t already have one, install a fire pit or small portable fire bowl to take the chill off cool autumn evenings. Place the fire pit on a patio or in a backyard area where there’s already seating. Take time to gather around with family and friends to toast marshmallows and reminisce about summer.
Check out your local nursery for end-of-the-season bargains. More expensive trees and shrubs are often discounted so that nurseries don’t have to carry extra inventory through the winter. Plant new specimens as soon as possible and keep them well-watered until they go into dormancy.
Now that the weather is cooler, it’s a good time to divide and move perennials. Do this at least several weeks prior to your average first hard frost in order to give plants time to recover from transplant shock and establish new roots. Cover garden beds with several inches of mulch for extra winter protection.
Rather than cutting back all of your perennials now, leave plants with seed heads, such as coneflowers, asters and ornamental grasses to provide food for your feathered friends through the harshest months. Make sure your garden includes native trees and shrubs with late-season berries, such as hawthorn, viburnum and beautyberry for seasonal colour as well as additional food for wildlife.
Incorporate eco-friendly practices into your autumn cleanup routine. Instead of bagging fallen leaves to be hauled away, finely shred leaves with a mower and layer or work them into beds to enrich the soil. Add leftovers to the compost pile. Winterize compost by insulating with a thick layer of leaves or straw to trap the heat that is generated as organic matter breaks down. Cover with a permeable cloth to allow moisture in and to keep material from blowing away.
By late winter, gardeners are eager for any sign of spring. Autumn is the time to plant spring-blooming bulbs to fill bare spots in the perennial border, or along pathways where they can be seen up close. Plant scented flowers such as daffodils or hyacinth near your home’s front entrance where the fragrance will be most enjoyed.
Protect your pots
In colder climates, wash and store ceramic and terracotta pots in a cool, dry place where they won’t freeze and crack. Sturdy metal, stone, fibreglass or plastic pots can be left out and used for autumn and winter arrangements.
Make a list of what worked well in the garden, and what could use fine-tuning. Is a key tree getting too big? Did design elements such as hardscaping and plant combinations work together effectively? Think ahead to next year’s projects, such as building a new path, patio or water feature.
Put the patio and tools to bed
Wipe down patio furniture with mild soap and water, and store in the garage or garden shed. Scrub excess dirt from garden tools and oil the metal parts to prevent rust. Store tools in a cool, dry place. Disconnect hoses and drain for storage, and cover faucets and hose bibs with an insulating material to keep them from freezing.
