What is wrong with my blackberries? (pics included)
My Natchez blackberry plant just does not seem to produce quality berries. I am not sure what I am doing wrong? This plant flowered fairly well in the beginning of spring, but the berries it produces are just not fully formed. You can see from the pics that only a few of the "bulbs" on the berry form, and the result is a tiny little mutant berry.
Can anyone help me out with this? It has been in a general potting mix amended with some pine bark fines. I fertilize every so often with liquid Miracle Gro. It gets sun for most of the day and I try to keep it watered, but not overwatered. It seems to have some nice new growth coming from the base of the plant, so I am not sure what is going on with the berry production?
I am pretty new to gardening, so any help would be appreciated.
