Ya know... I don't think putting a greenhouse under some giant mulberries is a bad idea, especially in your neck of the woods. In the Winter, when you want lots of light in the greenhouse, the leaves are gone, letting the light through. In the Summer, the shade is ideal so the greenhouse doesn't get too hot. You're growing veggies outside by then anyhow. One of my greenhouses is in such a location. It's great for the wife's succulents.

As for dropping leaves, get the ol' blower out.
