I bought some succulents at home depot and I want to put them in my Rosy Boas tank, I'm just going to leave them in the pot and bury it in the aspen. But I'm worried about bugs. How can I sanitize the plants? So far I've deported them, shook all soil off, microwaved all soil, and washed plants with soap and water and a toothbrush. Then rinsed well. Is this safe?
