I bought an aloe vera plant this past summer to aid through some tough summer days (sunburn). I knew not to water it too much, and have left it fairly dry. When I checked on it today, i touched a leaf which was loose. When I investigated further, it seems my aloe vera does not have much of a root system, and easily lifted from the soil. The leaves closest to the soil seemed rotted where they attach to the plant, and easily separated. The plant is however, growing new leaves, (approx. 5 new since i got it). Am I doing something wrong or are the leaves that have come off just being shed naturally, and why does it not have much of a root system?
