I want to grow some sweet, mild flavored onion bulbs. Are the small onion sets sold at garden centers a good variety to plant, or should I use seed?
Onion sets can be planted to produce a quick crop of green onions, but they will not produce a good crop of bulbs. The onions sold as sets are pungent varieties which often go to seed before they produce a bulb in our area. The best way to grow a mild crop of onion bulbs in our area, is by planting seed of short or intermediate day length varieties. Grano, Granex and other short day varieties should be planted in early to mid November. Sweet Spanish, Italian Red and other intermediate day length varieties should be planted in early February. Mature bulbs will be ready to harvest in mid or late summer.
