Grow seedlings in recycled containers as greenhouses. Any clear plastic container will do. Use paper towel rolls or toilet paper rolls as a pot. When ready to plant, simply place the whole roll in the ground and plant.
Living wall art made with succulents is not only super easy to make and grow, they look great and if you keep them indoors (they need direct sunlight thou) they help purify the air. No matter where you live, you can hang a small picture frame filled with succulents. They make for great gifts also.
