Paul, you don't live that far from me, basically the same dry climate, just a zone warmer. You mentioned having a greenhouse kiwi, which tells me that your greenhouse is BIG. Which of your other fruits do you grow inside? What is planted in the ground and survives the winters there? I have tried blueberries, they died. We have a lot of lime in our water, so we planted them in half soil, half peatmoss, and it took them 3 years to all be dead. I have some berries that vine, got them from somebody else's garden. They thrive on neglect. I need a trellis for them and maybe they would reward me with berries. I was told they are boysenberries.
Tell me about the mulberries. If I remember, they are something like blueberries.
Yeah, I have the same thought when I read the title to this forum.
