I wanted to try onion sets (Red Karmen, White Dutch, Sturon) in the raised bed garden this year. I live in North eastern Canada. We can usually consider the last week of May to be our frost free start time, (I usually wait till first week in June) and the first week of October to be our first week of frost.
I have a greenhouse, and 6- 4'x6' cloche covered raised beds (4 mil plastic film). I would rather try the onions in the open environment (my 8x12 raised beds without covering), but if others figure the season is too short, or temps are not good enough in my area, then maybe I will reconsider the possible waste of time and space in the garden.
Whats your opinion regarding an attempt to grow onion from sets in my area? Our Day temp in summer are about 20-25 celsius, and in evening around 10-15 celsius, from mid June until mid September. After mid Sept our temps are about 10-15 during day, and about 5-10 at night, until the first/ second week of October, where nights dip below 0 celsius.
Thanks in Advance!
