60/ blackberries / raspberries I grow native black raspberries and thornless cultivars of raspberries and blackberries. They don’t get any extra water than nature, but I do give a bit of fert. I keep the blackberries caged. It’s a dwarf variety. The raspberries are too big. I am able to get some berries off raspberries in the spring but the birds get most of them. I do use the leaves: dried/ground into powder in flours for noodles/breads or whole in tea.
