Blackberries now have well formed berries well on their way to being ripe in 3-4 weeks. A couple instances of blackberry winter one ongoing which I am told by old timers May is when it always used to happen. Sometimes now though it'll be 6-8 weeks early.
As things are today should have a strong harvest, and until that time can document the changes the vines go through both below and above ground. As blackberries are a strong promise for symbiosis main stays.🌿
