How to Grow and Care
Aloe is a very forgiving plant, and a well-grown plant can be quite beautiful. However, as with all succulents, Aloe must never be allowed to sit in stagnant water, and the plant should be carefully monitored to watch for signs of overwatering. Prefers warmer temperatures of 70ºF/21ºC to 80ºF/27ºC but will survive down to 40ºF/4.5ºC. Feed with a cactus fertilizer in the summer only. Suspend feeding in the winter as the plant goes dormant.
Aloes are not particularly fast-growing and will only rarely need repotting. Repot plants in the spring that are tipping over their pots or have ceased growing. Use a fast-draining potting mix with one-third sand or pebbles.
