Due to poor soil quality my brassicas have never grown that well, but are doing better this year than they ever have. My concern is the under ground growt of the actual fruit seems to be very little. I am only seeing tiny radishes and turnips. I applied 150lbs per acre of urea a couple weeks ago before a rain and I'm wondering if I shouldn't add more before it rains again? The deer are eating the leafy greens, but I was hoping to have some tubers by now! Any thoughts?
