Bought two of these plants about two weeks ago from a local nursery. They came very healthy and now appear to be dying. I cannot tell if I am over watering or under watering. Leaves are dried, curling, and browning now. I had them in full sun and watering every 2-3days with collected rain water. I have any amount of sun available for them to be moved to... planting in ground is not an option but I had planned to move them to larger containers with well drained soil.
