When to Plant

Planting dates vary by crop. The average last date of frost in Hamilton is this weekend - around April 29. So most things can go in the garden by then. There are even some hardier plants which could have been planted even three weeks ago. At the same time, there are some plants that need warm nights and days, not just absence of frost, and these shouldn't yet be planted.

Early crops:

  • Plants: Cabbage, Broccoli, Cauliflower, Onion (sets)
  • Seeds: Spinach, Peas, Beets, Lettuce

Late April / Early May:

  • Seeds: Chard, Carrots, Bush beans

Mid-May:

  • Plants: Peppers, Tomatoes
  • Seeds: Melons, Zucchini, Cucumbers, Squash

A great resource on planting dates is the Vegetable Garden Planner, available locally at Lee Valley.
