Dorothy, Dennis, et
got my lst spuria I planted it like a TB, and it took quite a few years before
it multiplied and bloomed. Subsequently I learned from Larry Harder and
others (confirmed by Jim Hedgecock in Sept., by the way) that spurias have to be
put deeper, perhaps as much as 2 inches. Much more satisfactory results in
terms of quicker bloom since then, and I never have mulched them. Never a
mouse problem, either. I can't speak to borers, since I don't have them (I
knock on all available wood, and give thanks often) in my garden.
