RE: Grow 'Em Right {the book}
Some of my brassica was eaten in the early fall as well. Specifically, right after the first frost and in my smaller plots. However, we had some that was still standing just a few (3 or so) weeks ago in plots larger than 1 acre... IMO, anytime you can offer more forage you are taking a step in the right direction even if it only lasts til December or January. It is still better than the deer having a food shortage in late October or November once the crops are harvested and mast becomes more scarce. TGK
