How to Grow and Care
Aloe is a very forgiving plant and a well-grown plant can be quite beautiful. As with all succulents, it is essential that Aloe is never allowed to sit in stagnant water and the plant should be carefully monitored to watch for signs of overwatering.
These succulents are not particularly fast-growing and will only rarely need repotting. Repot Aloes in the spring that are tipping over their pots or have ceased growing. A well-drained potting mix is essential. Use a cacti or succulent mix. During repotting of a larger plant, it is possible to carefully divide the root ball. Some varieties of Aloe will send off offsets that can be potted independently.
Aloe plants need strong, bright light. They can withstand full summer sun, once acclimated. In the winter, provide bright light. These plants prefer warmer temperatures of 70 to 80 °F (21 to 27 °C), but will survive down to 40 °F (4.5 °C). Feed with a fertilizer for cacti and other succulents in spring and summer only.
