We got tired of our red wriggler worm farm and retired them to the garden (zone

. It’s been about three years and we haven’t seen any in a while. The garden is now full of regular earth worms and everything else that composts plant material. Just keep feeding the soil, worms are just a pice of the puzzle. If you have bugs eating your plants, don’t kill them, feed them more. We had major problems with cutworms, slugs and everything else eating our seedlings. We found out all you have to do is feed them and they will be happy. Never leave a seedling out in bare dirt, it’ll be done the next day.
Big tip: Watch the wasps. The day I saw them eat a horn worm was the last day I killed them.
