I planted late, so my cabbage, turnips, beets, and carrots are still in the early stages of growth. I'm going to put trellises and plastic over them until they get bigger. My collards are getting big, not quite as big as yours.
Did more weeding, gave the results to very happy chickens.
I'll be placing a cattle panel trellis over the bed and add plastic once we get close to a frost. I did that one year with collards and lettuce, and they grew really well. I only lost the lettuce when it got especially cold outside, below 20F.
