Defective soft flesh colored drupelets on blackberries?
This is the first year for my blackberries. They are triple crowns growing in containers. I've never seen blackberries this large. Wow.
However, some of my blackberries are defective. For reference, as the backberries ripen they morph from white to red to black. When I was a kid, the "big box" of crayons had one labeled "flesh" color. On a percentage of my berries, some of the drouplets are "flesh" colored and mushy soft, while the surrounding areas are starting to turn black and are still hard. On some berries, it effects only a few drupelets. On other berries, it effects most of the berry with only a few normal drupelets. As the berry continues to ripen, the normal surrounding druplets swell, sort of crowding out the defective areas. The defective areas are turning brown and drying up sort of like a fall leaf.
I haven't tasted these because the berries aren't ripe yet.
What's wrong? What's the solution?
