I have two large barrels on south side of house filled with dirt.. When can I plant lettuce seeds in these containers?
Hennepin County Minnesota
You can sow early "cool-season" crops such as lettuce, cabbage, cauliflower, broccoli, Brussels sprouts and onions right after preparing the soil in your barrels. Floating row cover made from spun-bonded polyester will help extend the growing season this spring, protect the lettuce from insects and frost.
