With shorter days and cooler weather coming, here’s how you can ensure your garden survives the season and thrives again come spring.
Start by clearing any plants that have passed their best. This prevents pests and pathogens from overwintering in your garden beds. Don’t overdo this, though: leave some seed heads and plant stalks for birds and beneficial insects. Native bees, for instance, nest in hollow stems and need that shelter to survive winter.
Fallen leaves should be removed from the lawn as this will suffocate and smother the grass, and potentially cause bare areas. Leaves in the beds are fine as they will rot down and add essential organic matter to soil and also provide cover as a natural mulch.
Pro tip: Only compost healthy plant material and avoid composting anything with disease or pests.
Perennials die back in the winter but return stronger in the spring. To help them survive and store energy ready for spring growth:
This helps regulate soil temperature and moisture levels.
Mulching is one of the best winter prep steps you can take. It:
Apply 2–4 inches of organic mulch around your plants, but keep it a few inches away from stems and trunks to prevent rot. Don’t apply too much as this can harbour moisture around the base of the plants and encourage mould and rot development.
Autumn and early winter are ideal times to improve your soil’s health. Add compost or well-rotted manure to your beds to slowly break down over winter: enriching your soil in time for spring planting. Use the leaf matter as stated earlier.
Winter sun, wind and fluctuating temperatures can damage young trees and shrubs. Here’s how to help them survive:
Don’t forget your equipment! Frozen water can crack hoses and damage irrigation systems. Be sure to drain any hoses and irrigation lines thoroughly and store them in a dry place. Then, clean and oil any tools in storage to prevent rust.
If you grow tropicals or tender perennials, bring them inside before the first frost. Inspect for pests first, and place near a sunny window. You can water these less than usual though, as houseplants typically go semi-dormant in winter.
Winter is nature’s pause, and is a perfect time for you to reflect on your garden ideas:
You’ll be ready to hit the ground running once the soil warms up!
