Easy nuts to grow in Maryland
I have been informally advising some local community groups on planting fruit trees that require little care, and they always also ask about nuts and I don't know enough to answer. What are some nut trees that are reliable producers with no sprays or other labor-intensive maintenance? I am planting some pecans now, and the only other nuts I know about are the black walnuts that grow everywhere here but are hard to shell and little meat so nobody uses them. I looked around for a webpage and could not find much, but it sounds like pecans, hazelnuts, shagbark and shellbark hickory, chinkapin, walnut and chestnut are options. Nut pine too I guess. Are these all pretty reliable with good sun soil and pollination, or are there significant disease or pest problems on them?
