For cold-climate gardeners, March means we’re getting close! Spring gardening is on its way. Now is the time to get seeds started indoors and create some garden art for a fresh, new start.
For more, see garden task lists for each month here.
March Garden Tasks
These are examples of tasks I like to do in my cold-climate garden (zone 6). Every garden is different, and we each adapt based on climate, growing zone and conditions, the plant species, challenges, and time and resources available. Please take the inspiration and run/grow with it.
Here in southwestern Ontario, Canada, March is the month of hope! Spring is in the air. No matter what snow storm might be thrown our way, there’s a definitely a feeling of spring in the air. Early-flowering bulbs pop up, the sound of bird mating calls rings out from morning to dusk, and tree sap runs once again.
Monthly Garden Tasks
- There is a complete, printable Spring Gardening Checklist here.
- Check on planted containers in storage including bulbs and fig trees. Keep lightly watered and mouse-proof.
- Maintain winter vegetable garden. Water and air as needed.
- Late winter is prime time for pruning many trees and shrubs. And a good time to visually assess their structure and health.
- Unless frozen, turn your compost pile when you can. Continue easy winter composting method.
- Want to tap trees for syrup? Get your supplies ready.
- Want to sow early veggie crops? Set up season extenders for a jump start.
- Make sure your pond does not freeze over. I keep a pump running and a hole open in the ice.
- Make sure nesting boxes are ready for bird mating season.
- Also consider adding bee, bat, or owl boxes if you have a larger property.
- Wash your bird feeders and suet cages on a regular basis. The freeze/thaw cycle can cause the spread of disease.
- You can track the hummingbird migrations on this map to know when they’ll arrive in your area.
- It’s indoor seed starting time! Grow annuals including veggies, and perennials.
- It may be time to start sweet pea seeds too.
- Grow salad greens, and other veggies and herbs indoors any time of year.
Use that restless March energy to create some new art for your garden.

Phenology is the science of observing annual first events in nature.
When flower buds open. When peepers first peep. When bees appear. When migrations arrive. When bulbs pop up. The list is endless.
Seasonal changes prompt natural responses in the plant and animal kingdoms. It is interesting to note these events and compare year over year.

- Flowering bulbs are blooming.
