I've never tried to grow blackberries here, but I got one of the new, thornless ones at A&P Nursery about a week ago. It's a Christmas present for my little GGS who LOVES to garden. Now I need to find the perfect spot for it in my yard. (It will die if it goes home with him!) If you grow them, I'd love some advice on siting it.
Btw, I don't know who's shopping at A&P (Baseline just east of the 101), but I ran into such a nice, honest young man that I am now obliged to make that long trip just to shop there. We - my GD and I - were going to spend a fair amount on shrubs for her yard. He was very helpful providing info about each, but he actually advised her to wait to plant rather than risk frostbite. She was in one of those got-to-do-it-today modes and the same advice from *me* didn't have the same weight as from him. She did buy some asparagus fern, so he did make a sale.
