What’s the best remedy for thrips? I bought a String of Rubies plant on Monday and just now found them on her. I’ve checked all my other plants very thoroughly. I didn’t see any on them. But now I’m nervous. I’m very new to being a plant mama, so I want to make sure I correct the problem and not let the infestation affect my other plants. I’ve already quarantined her to another room that has no other plants, but I want to be proactive in preventing my other girls from them as well. What do I do in this situation?
