How do you fertilize blackberries, raspberries & strawberries?
I am trying to figure out the best way to fertilize blackberries, raspberries and strawberries. I currently fertilize only in the spring, and it seems like they could use a little more later on in the season. Oregon State (which seems like it would be a good source since berries grow so well in Oregon) recommends taking the total amount of fertilizer, divide it into three amounts and feed the berries in early spring, late spring and early summer. I have read so many different methods, that I'm not sure which is the best. Just wondering what has worked best for those who grow these berries?
