Planted the gojis last spring. It has been interesting to watch their growth habits. In spring, during the cooler months, they are fully leafed out. Come the very hot months of the summer they lose many of their leaves in response to the heat. I have seen this in the desert when leafy trees lose leaves because of the searing heat of the Sonoran summer. As autumn arrives the gojis become fully leafed out. Now they are flowering in early October. Will have to wait and see when the fruit shows up.
