Hello! I'd like to ask you some advice. I get orchid care tips on my email and yesterday I read that "Listerine - this "2-in-1" home remedy can be used as a spray at full strength for short periods (about 2-3 consecutive days is okay) as a preventative measure on your orchids... Simply spray your plant lightly once a week or so, and you'll have yourself a quick and easy way to keep away unwanted pests and disease, and ensure your plant stays healthy".
Has anybody used Listerine like this? Should I use it only on leaves or also on the pot mix?
