I suppose the other point about my conditions is that our soil is quite thin and dusty, so it dries out readily in summer, especially under grass and / or trees. I think that's probably a good thing for many summer dormant bulbs of a Mediterranean bent, so long as they don't need a real baking. Tulips seem to do well here for example, even though 1000ft up a Welsh hill with more than 1000mm of rainfall annually doesn't immediately sound like tulip country!
