Berry plants not growing
I planted several raspberry and blackberry plants about 3 months ago, and they aren't growing. A few have died. Others have branches with pale leaves that look like they are about to shrivel up and die, but then have one or two short branches with wonderfully healthy-looking leaves.
I assume the sickly looking parts were existing branches, and the healthy looking parts are new growth?
The plants are no more than 2 feet tall and aren't wide either. They have full sun and plenty of space. I watered them twice a week when it was hot and dry, but haven't watered them in a couple weeks because we've had rain about every 3 days lately.
Any advice on what I can do to get them to grow?
