How much h2o2 can you put in the soil of a plant without the plant being affected? I have some bugs in my soil and I've tried some different things to get rid of them like tobacco juice but without success. And I don't want to use some chemical poison. So I'd like to try to water them with some h2o2. As strong as I can go and see what it does.
H2o2 is not going to help an insect problem. It could be detrimental to the beneficial microbes in the soil also. H2o2 kills bacteria, and there are some bacterias that help keep your soil healthy.
