Peroxide is used around plants but I can't tell you how strong (weak) it needs to be. I did a little searching but sites were commercial and not sure reliable.
Keep your plants healthy , they should never be ''soaking" wet. Keep them in tight (small) pots so they dry their soil. If you have bright light, keep succulents that like dry soil.
