As the frost thaws the days lengthen, gardeners in Ontario, Canada, eagerly anticipate the arrival of spring. It’s a season of renewal and growth, but before your garden can flourish, it’s important to give it some attention after the long winter months. Spring garden cleanup is a crucial step in preparing your garden and lawn for the growing season ahead. In this guide, we’ll explore the essential tasks to tackle in your Ontario garden during the spring season.

  • Clear Debris: Begin your spring cleanup by removing any debris that has accumulated over the winter. This includes fallen leaves, branches, and any other organic matter that may have collected in your garden beds and lawn. Clearing away debris allows for better air circulation and helps prevent the spread of diseases and pests.


  • Rake and Aerate: Raking your lawn not only removes dead grass and debris but also helps to loosen compacted soil and allows for better water and nutrient absorption. Aerating your lawn further improves soil compaction by creating small holes that allow air, water, and nutrients to penetrate deeper into the soil.


  • Prune Trees and Shrubs: Spring is an ideal time to prune trees and shrubs before new growth begins. Remove any dead or damaged branches, as well as any crossing or rubbing branches that can cause problems as the plants mature. Proper pruning encourages healthy growth and improves the overall appearance of your landscape.

Divide and Transplant:

Spring is also a great time to divide and transplant perennials that have become overcrowded or outgrown their space. Dividing plants not only rejuvenates them but also allows you to expand your garden to share with friends and neighbors. Be sure to water newly transplanted divisions thoroughly to help them establish quickly.

  • Weed Control: Weeds can quickly take over your garden if left unchecked, so early intervention is key. Pull weeds by hand or use a hoe to remove them from garden beds and pathways. Applying a layer of mulch can help suppress weeds growth and retain moisture in the soil.
  • Inspect and Prepare Tools: Before you dive into your spring gardening tasks, take some time to inspect and prepare your tools. Sharpen blades, oil moving parts, and replace any worn or damaged parts as needed. Having well-maintained tools will make your gardening tasks easier and more efficient.
  • Soil Preparation: Test your soil pH and nutrient levels and amend as necessary to create optimal growing conditions for your plants. Adding compost or organic matter improves soil structure, fertility, and moisture retention. Incorporate amendments into the soil before planting to give your plants a healthy head start.
  • Start Seeds and Plant: Once the threat of frost has passed, it’s time to start sowing seeds and planting seedlings in your garden. Consider starting seeds indoors several weeks before the last frost date to give them a head start. Choose varieties that are well-suited to Ontario’s climate and follow recommended planting guidelines for optimal growth.
  • Monitor for Pests and Diseases: Keep an eye out for signs of pests and diseases in your garden and take prompt action to address any issues. Remove affected plants, and consider using organic pest control methods to minimize damage to your garden.
  • Water and Mulch: Finally, ensure that your garden receives adequate water, especially during dry spells. Mulching garden beds helps retain moisture, suppresses weeds, and moderates soil temperature. Apply a layer of mulch around plants, leaving a small space around stems to prevent rot.
