Aloe plants do well when kept watered and given good access to sunlight but will come back from the brink if forgotten about! If left to dry out for too long the leaves will shrivel and become misshapen. If a leaf dies you can remove it by gently pulling from the base. The plant will naturally infill any gaps with the next few leaves. Free draining soil is best and they can be potted on without any bother. They will soon grow to their new surroundings.
