Pruning blackberries

We pruned our blackberries last week. This was not a top and side pruning. We had to remove all the old canes that bore fruit this year. The dead canes are entry points for disease if you leave them. They have to be cut out, removed, and burned. So basically you have to kind of crawl along the whole length of the row and cut and pull. This is especially tricky on the thorny ones and I have the scratched arms to prove it! I put together a small photo album so you can see what we did. The plants look much better now. All the growth is up high so the picking should be much easier next year. I still need to come back and put some supports up for some plants that got too top heavy and fell over. Of course this only happened on thorny plants. Why?!?!?!
