What to plant in April Canada

What to plant in April in Canada depends entirely on your zone — this page answers it for every band. April opens outdoor sowing across most of southern Canada. Direct sow carrots, peas, radish and spinach once soil reaches about 5-7C, harden off transplants, and keep tender crops indoors — the last frost has not passed anywhere yet.

April garden jobs

  • Test soil temperature at seed depth before direct sowing.
  • Harden off transplants over 7-10 days — Canadian spring wind is as damaging as cold.
  • Prepare beds and add compost as soil becomes workable.
  • Set up low tunnels or cloches to bring sowing dates forward.
  • Keep an eye on frost warnings; April warm spells are routinely followed by frost.

Common April mistakes

  • Planting tender crops out during an April warm spell, weeks before the last frost.
  • Skipping hardening off, which is more punishing in Canada because of the wind.
  • Sowing carrots into cold, wet soil where the seed rots.
  • Assuming the Prairies can follow southern Ontario dates.

Turn April's jobs into a written plan. The Canada Vegetable Garden Planner (printable PDF) has frost-date planning pages, bed layouts, crop rotation, a sowing log and a harvest tracker — 70 printable pages.

Frequently Asked Questions

What can I plant in April in Canada?

In the long-season band, carrots, beets, peas, brassicas, lettuce and potatoes. In the medium band, peas, spinach and radish as soil becomes workable. On the Prairies, still nothing outdoors.

Is April too early to plant tomatoes in Canada?

Yes, everywhere. The earliest safe transplant date is after your last frost — late April at the very earliest on the coast, and late May on the Prairies.

What soil temperature do I need in April?

About 5-7C for peas, spinach and radish, and 7-10C for carrots and beets. Below that, seed sits and rots rather than germinating.
