“Life on the rocks’ is just what the name suggests – a plant that “lives on a rock’. As the roots grow over the rock it takes on a gnarled bonsai appearance that keeps improving with age. There is no potting mix used at all. When you fill the dish with water, the volcanic rock absorbs the moisture making it available to the plant roots. This encourages moss to grow on the rock too which further adds to the bonsai like appearance.
But you do not have to be a bonsai master to keep your “Life on the Rocks’ looking good. There is no pruning, training, or repotting. Just add water!
