Michele, thanks so much for the information! Looks like I've done no harm, according to your info. My main reason was earthworm feeding, and if it helped the seedlings, that would be a bonus. My new seedling bed was created from killing part of the lawn, and when I was digging, I found almost no worms. My flower beds are full of them, and I'm going to top dress all of the plants in the beds, mostly to feed the worms!
Now if my other seedlings would grow just a bit more, I'd feel better about putting them in the garden. They are still pretty small, and I'm not sure how big they should be before I transplant them. And me being the idiot that I am, I forgot that I still had seeds germinating in the fridge! Looks like those are going to have to spend the winter in the greenhouse, and I'll just hope for the best! I'm thinking I better plant them in one gallon pots instead of the smaller pots.
Tina, I've heard that willow-water is good, but I have never used it.
