Gardeners in Langley, BC can expect the average last spring frost around March 11, and the first fall frost around November 16, based on historical Environment Canada frost data for the area. That gives Langley a frost-free growing season of roughly 250 days. Actual frost dates shift by a week or two year to year, so use this as a planning baseline rather than an exact guarantee, and always check your local forecast before moving tender plants outside.

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 Langley's first fall frost approaches in November, it's time to plan the last harvests for anything frost-sensitive still in the ground.
Approximate dates for common crops in Langley, worked out from the local last frost around March 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.
