When To Plant Walla Walla Onion Seedlings Out In The Garden

Question

Most information I have seen states that onions are a cool weather crop, and can be planted in early spring, but the package says to wait until all danger of frost has passed. My last frost is April 26, zone 5b. Does that mean I should not plant out SEEDS? My onion plants are about 5-6″ tall. Thank you.

Answer 1

It means you shouldn't plant seeds in the ground or your seedlings outside till all danger of frost has passed. You already have a jump on the season by starting your indoors.
