Terrariums are a great way to bring a little green to your indoor space, but why not add more colors of the rainbow? By adding colored sand to the base of the terrarium, you can create even more visual appeal to the bottom layers. The process is just as fun as it was when you were young creating sand-art masterpieces at summer camp.
This idea comes from our friend Ashley Poskin. Sand-art terrariums are fantastic homes for air plants, which can thrive on almost any surface. If you want a terrarium with succulents or foliage, you can do that, too. While succulents don't necessarily thrive in terrariums, they can survive, but your best bet is to choose some leafy greens. A few varieties to consider: friendship plant, air plant, spider fern, nerve plant, and the venus fly trap. For maintenance, water at the base of the plant as needed, or place a small ice cube at the base of the plant to keep the terrarium clean.
