I wish it was the same with my two trees..... Only one dried up, but when I pruned it, a new one sprouted, which is now progressing nicely...
For red goji berries, the daily intake is 20g-50g
I was lucky to get to a tree with those black berries... Because there is a goji tree nursery near us...

It's good that you found such a way..🤗
Have a nice day☀️
