My Dad was helping me with our plots back in early August. I had planted this plot in strips and the brassicas had been planted about 2-3 weeks before. They were 6-10inches tall. We broadcast rye, oats and fertilizer on the unplanted strips and my Dads job was to roll that in. He did that great, everything was perfect. We then spread clover seed and we were going to roll it in. Well, my dad got confused and before I could stop him, he rolled the brassicas 3-4 times with the wheeler and lawn mower. All of the brassicas were smashed, leaves torn etc. It looked pretty bad. I figured that strip was done and was going to plan B. Went back 2 weeks later to do some work and to my surprise the brassicas were up, growing and had gained some height and leaves. Granted we had a nice 3/4 inch rain 2 days after he rolled them over.
