I think "diluted liquid 'produce' from Californian worms" would make them very happy indeed! As Barbara suggested, I do play watering by ear - more water during the hot months, less at other times. Generally once a week, but that can be more or less depending on the weather. But never soggy. This summer I made some compost tea for some of my seedlings and they seemed to like that, as the leaves got darker green.
