I have gotten a small worm box started and I plan to start 2 more. I hope to have about 3 gallons of castings to mix with my houseplants and mix in my garden soil for my veggies this year. It is easy for the outdoor veggie garden but when do I want to add the castings to my indoor plants? I have mostly succulents and I don't want to harm them. I know they like to have organic fertilizers but I don't want to harm them or overfeed them if that is possible with worm castings.
