You can cover flower pots with moss.
Moss, the shade loving, green velvet of the natural world, offers visual calmness and serenity wherever it grows. It's the very reason moss is often used in Japanese gardens. When you see it growing on flower pots we think of quaint English gardens too. We live in a hurry-up world where everything is supposed to happen fast. If you've decided you'd like a moss-covered flower pot, it's going to take time for it to grow naturally. There is a way, however, to get green moss on your flower pots today.
Instructions
1. Coat the outside of the flower pot with spray adhesive.
2. Place sheet moss over the surface and press it in place. Use scissors to cut and fit it to the shape of the flower pot.
3. Use a hot glue gun to secure the moss in spots where more hold is required.
4. Stretch rubber bands over the outside of the flower pot and leave them in place until the spray adhesive and hot glue completely cure.
