Planting Instructions



Onions can be planted from seeds, sets or transplants. Transplants form better bulbs for storage while sets are best for fresh eating and green onions. Onions seeded in the spring will form good storage bulbs provided the season is long enough for them to reach full maturity.

Plant sets 1" to 2" apart and thin by harvesting.

Plant transplants 5" to 6" apart to allow room for proper bulb development.

Onions grow well in rows, containers, or wide beds so long as spacing is maintained.

Tips
