Growing vegetables in Zone 1
Growing vegetables in Zone 1 is all about speed and season extension. With a frost-free window of only about 50–80 days (last frost around Late May – mid June), the winning strategy is fast-maturing varieties, transplants started indoors, and row covers or cold frames to stretch both ends of the season. Cool-season crops — greens, roots, and brassicas — are your most dependable producers.
The vegetables below grow well in Zone 1. Use the zone's frost dates — last frost Late May – mid June, first frost Late July – mid August — to time sowing and transplanting right.
Vegetables are the backbone of most food gardens. Success comes down to matching crop requirements — days to maturity, heat or cold tolerance, spacing — to your zone's growing window. Short-season zones prioritise fast-maturing varieties; long-season zones can grow almost anything.
