What is the optimal growing environment for thornless blueberries?

3 thornless blueberry plants are barely surviving. there were woody stems without leaves during this summer which I trimmed just above the nodes. fruit production was minimal but healthy and lasted a few weeks. They have never increased their height. full sun exposure. Presently, the woody branches remain with a couple of green leaves at the top. With winter approaching, what enviromnent will keep them alive, and what can be done about the growing conditions during the following months. Perhaps you will be able to indentify the species from these phtghs. please help. I have had these plants for 2 years..

2x - 8 to 12 inches estimated

    These plants are thornless blackberry. I would feed them with miracle gro or whatever you choose and mulch good for winter, if you live in cold area. Also I would put the acidic product on them because it will help with growth. My son puts a cup of cement mix to a bucket of water ( 3 - 5 gal.) and it really works wonders. You will also want to keep the new vines for next year's berries. They bare on the new vines and the old vines die off.

    Do you have these planted in your lawn? If so if you fertilize your lawn, it causes more grass to grow, but you don’t want that fertilizer on your gardens or fruit. You want fruit not more leaves. Make sure your soil is acidic.

    My neighbor uses ashes from his fireplace, just put on the ground near the plants. And they grow like crazy!
