you water them at all in the summer time, you'll find they'll
disappear/die pretty quickly. For this reason, you can't plant annuals
over top of them or have them in any flower garden where they'll be
watered as part of the weekly routine. So damp in spring is good - dry
in the summer and damp again in the fall will mimic their native
