Preparing Your Garden for Winter: Essential Fall Tasks

The Quebec fall, with its vibrant colours, marks the end of the gardening season. Before putting away your tools, it's crucial to prepare your garden for winter to ensure a beautiful revival in the spring. Whether you're in zone 3, 4, or 5, follow this comprehensive guide to protect your plants and ensure their health during the cold months.

Lawn: Preparing the Green Carpet for Spring

A healthy and resilient lawn is key to a beautiful garden. Here's how to take care of yours in the fall.

  • Overseed or lay sod to fill in sparse areas and ensure a thick, green lawn in the spring.
  • Repair damaged areas caused by drought or wear and tear.
  • Mow the lawn until it stops growing, gradually lowering the cutting height to 3.5 cm for the last mowing.
  • Fertilize with a special fall fertilizer to strengthen the roots and promote vigorous growth in the spring.
  • Treat for grubs if necessary to prevent root damage.
  • Clean up the yard by collecting fallen leaves to make nutrient-rich mulch or compost.
  • Protect the edge of the street with a tarp to prevent damage caused by salt, gravel, or sand used in winter.

Flowerbeds and Perennials: Preserving Beauty and Preparing for Blooms

Flowerbeds deserve special attention in the fall to ensure beautiful blooms next spring.

  • Weed regularly to eliminate competition before winter.
  • Plant spring-flowering bulbs like tulips, daffodils, and hyacinths for a colourful garden in the spring.
  • Bring in annual bulbs like Callas, Oxalis, Caladiums, Begonia tubers, Dahlias. (Read the article on how)
  • Clean up the flowerbeds by removing plant debris and faded plants before the first frost.
  • Plant new perennials to enjoy an extra growing season in the spring.
  • Cut back perennials that have finished their flowering cycle to about 15-20 cm from the ground.
  • Divide perennials that bloom in spring, such as daylilies, peonies, asters, and phlox, to multiply and rejuvenate them.
  • Divide and transplant invasive perennials or those that need rejuvenation. (Read the article on how)
  • Protect less hardy perennials with mulch or a winter cover, especially those planted or divided in the fall.

Potted Plants: Protecting and Extending the Season

Potted plants require special attention to overwinter safely.

  • Bring tender plants like geraniums, fuchsias, begonias, impatiens, lantanas, and other tropical or annual plants indoors to a bright and cool location to protect them from frost.
  • Extend the season by repotting fall plants with spectacular foliage, such as ornamental cabbage or chrysanthemums.

Trees and Shrubs: Ensuring Their Health and Protection

Trees and shrubs, essential elements of the garden, need to be prepared for winter.

  • Plant new trees and shrubs in the fall to give them time to establish roots before winter.
  • Fertilize with a fertilizer suitable for deciduous trees, conifers, and hedges to strengthen them before winter.
  • Water conifers deeply to allow them to build up water reserves.
  • Mulch around the base of trees and shrubs to protect their roots from frost and retain soil moisture. (Read the article on why to mulch)
  • Install winter protection (covers, sleeves, etc.) when the ground is frozen or after a snowfall to prevent damage from cold and wind.
  • Check the trellises of climbing plants and protect them if necessary.

Vegetable Garden: Harvesting and Preparing for Next Year

Fall is the time to harvest the last vegetables and prepare the vegetable garden for the next season.

  • Harvest late vegetables such as cabbage, leeks, and carrots before the first hard frost.
  • Store root vegetables (potatoes, beets, etc.) in a cool, dry place.
  • Plant garlic in the fall for a harvest in early summer next year.
  • Protect strawberries with a straw mulch to insulate them from the cold.
  • Cut back raspberries after harvest to stimulate new growth in the spring.

Composting: Making the Most of Garden Waste

Fall is an ideal time for composting, thanks to the abundance of organic matter available.

  • Collect fallen leaves, grass clippings, faded plant stems, and vegetable peelings.
  • Alternate layers of brown materials (dead leaves, branches) and green materials (kitchen scraps, grass clippings) for a balanced compost.
  • Aerate the compost regularly by turning it with a fork to promote decomposition.
  • Add a compost activator if necessary to speed up the process.
  • Use the mature compost in the spring to enrich the soil in your flowerbeds and vegetable garden.

Additional Tips: Promoting Biodiversity

A welcoming garden, even in winter, attracts wildlife and contributes to biodiversity.

  • Maintain your tools: Clean and store your gardening tools before winter to preserve them.
  • Prepare the garden for birds and wildlife: Install feeders, birdhouses, and leave areas of wild vegetation.
