Ask at Canyon Creek Nursery. John Whittlesey, who owns and runs it, should have good knowledge of how best for you to grow them; email johnccn@sunset.net; phone 530-533-2166. Although he is well north of you, it still gets hot and dry there (Oroville), so he should have some first-hand experience.

Thank you Mike, I appreciate the advice. So far they're looking very happy in their morning sun under a tree.
