Elfrieda - No the red wigglers will NOT survive in the ground soil for very long. I sift my worm casting and add all the worms that I pull out of the castings back into a newly started worm bin. I love my worms! The castings are the best! The big note on worm castings that I have noted is that the stuff (just a handful amount) helps any plants with transplant shock. It works beautifully. Instead of the plants dropping a few leaves and sulking, they just keep growing like they had been in their new home forever. So I hope to always have a worm bin. I am hooked on the worm castings in my garden and in my potted plants!
I had not heard of Chitin. I am going to have to do some research about that. Does it repeal or kill root-knot nematodes? I would sure like to know!!!
Elaine - No edibles here. But I did recently purchase some seeds for California Wonder Sweet Peppers. (Wished I had found seeds for the "Snack Peppers".) Also got seeds for: Sugar Sprint Pea, Tomato Pineapple, Sweet Pickle Pepper, Lacinato Kale, Malabar Red Stem Spinach, and Nevara Lettuce. I will be starting some of those (or maybe all of those) next week while I am still off for the holidays. Probably in containers, unless I can make a new small raised bed in time.
