Well I have been seriously lax in updating this thread. Here are pics from my last two visits.
This series of photos range from late November to early December. I've got too many to keep the dates straight.
The radishes are doing extremely well. The deer are hammering the tops! This is exciting because they never touched the purple top turnips we planted for two years.
BTW, we added no nitrogen to the plots. Radishes are supposed to do REALLY well with nitrogen.
It's obvious in those pics where the deer are eating the tops. Others claim that they start eating the root later in winter.....I haven't seen that but will be watching for it.
