I am a newbie gardener who planted some blackberries in my backyard about a year and a half ago (late fall while dormant). The starts came from very massive and healthy plants in my dads garden.
These little starts are not doing so well. I lost about half, the other half barely grew last year, and more are dying off this year. The remainder are just not growing well (they remain 6 inches to 1 foot tall).
I did not amend the clay soil I put them in (newbie mistake), but have added fertilizer and nutrients. Are they root bound in the clay? Should I start over? I heard these things grow like weeds, I wish they would!
