In this range you'll find spring-planting, autumn-planting onion sets and heat-treated varieties. Spring-planting sets will give you a crop during June and July and autumn-planting varieties will be ready a few weeks earlier. Spring is such a busy time and planting onion sets and garlic sets in the autumn to overwinter gives you one less job to in spring! Heat-treated onions are less likely to bolt (run to seed) on planting, which occurs particularly in red varieties.

Companion planting: Try growing onions with mint to confuse and deter onion fly.
