I planted my cauliflower about 2 feet away from my strawberries. Which I realize now, they aren't good comapnions. Can I plants some green onions or lettuce between them and have them do ok, or should I move my cauliflower plants instead?
I would play it safe and move the cauliflower. Neither strawberries nor cauliflower are allelopaths so planting other plants between them won't make much of a difference.
Most likely, the reason why one would inhibit the growth of the other and vice versa would be because they compete for the same resources.
