Hi, I also saw your question about peach trees. It sounds from both descriptions that you are on the right track, but you need to slow down. If you have hard pruned (which is fine), you likely won't get any/any additional fruit this season. You appear to have a good acidic soil for the bberries, but if you overdo, you'll burn and shock. I have found a lot of help by googling questions, such as "when to fertilize blueberries" and such. Hope this helps a little.
