Aloe vera plants are succulents, so use a well-draining potting mix, such as those made for cacti and succulents. Do not use gardening soil. A good mix should contain perlite, lava rock, chunks of bark, or all three. A layer of gravel, clay balls, or any other “drainage” material in the bottom of the pot is not necessary. This only takes up space that the roots could otherwise be using. A drainage hole is drainage enough! Lighting: Place in bright, indirect sunlight or artificial light. A western or southern window is ideal. Aloe that are kept in low light often grow leggy. Fertilizing: Fertilize sparingly (no more than once a month), and only in the spring and summer with a balanced houseplant formula mixed at 1/2 strength. Water aloe vera plants deeply, but infrequently. In other words, the soil should feel moist after watering, but should be allowed to dry out to some extent before you water again. If the soil stays overly wet, the plant’s roots can rot.
