New gardener here, so I have one of those annoying newbie questions which brings instant wrath from experts. A couple weeks ago I bought two Apache blackberries from Lowe's. I planted them next to a 4 foot high chain link fence. I mean right next to the fence, about 6 inches away. I was under the impression that these needed a trellis, and I figured the fence would work well. I find out that Apaches are erect and need no trellis. Do I need to dig up and relocate my blackberries, or will they be fine against the fence?
