Does anyone use pebbles or other decorative materials (or even hydroponics pebbles) as a top layer to cover the potting mix around their houseplants? I only use them for succulents, but I’d like to do it to the plants that have plain soil exposed—partially because I think it will minimize those annoying little flies and partially because I think it will look nicer. Or will this harm the plants in some way? Any thoughts or insights are much appreciated! 🙏
