September is one of the busiest gardening months in Edmonton. Cooler nights bring relief to your plants and open the door for fall chores that set the stage for a healthy, beautiful yard next spring.
Refresh and Nourish
Start by clearing out spent or diseased plants. Compost what you can and dispose of what may carry pests. Work in compost or a balanced fertilizer into your soil to replenish nutrients lost over summer.
Plant for Tomorrow
September is prime time to plant spring bulbs like tulips, daffodils, and alliums. The cool soil encourages root development before the frost. It’s also a good month for planting garlic and hardy greens that can continue producing into fall.
Perennial Preparation
As perennials start to wind down, trim back what’s necessary but avoid cutting down early spring bloomers, as they set buds now for next year. Consider dividing and replanting crowded perennials to give them more space to thrive.
Support Wildlife
Leaving some seed heads or ornamental grasses standing provides birds and pollinators with a food source and shelter as the weather cools. This also adds texture and beauty to your garden into the winter months.
Yard Review
Now that summer is winding down, it’s time to do a walkthrough in your yard. Did summer wreak havoc on your grass? Does your deck need some help? Fence starting to fall down? Carpentry work can still be done during the fall and early winter and we are booking projects for 2026 already!
