Most warm-season crops (tomatoes, peppers, squash) need transplanting only after the last frost has passed, and are usually started indoors 6 to 8 weeks before that date. Cold-hardy crops (peas, lettuce, spinach) can often go in the ground a few weeks before the last frost. As Happy Valley-Goose Bay's first fall frost approaches in September, it's time to plan the last harvests for anything frost-sensitive still in the ground.
Approximate dates for common crops in Happy Valley-Goose Bay, worked out from the local last frost around June 11. Warm crops go out after frost, cold-hardy crops a few weeks before it, and anything with an indoor start is counted back from its sow date.
