Aloe plants in the desert produce a flower stem 2 to 3 feet tall topped with yellow or orange tubular flowers. Seedpods develop as the flowers fade away. The production of aloe seeds rarely happens to aloes grown indoors.
The best time to sow aloe seeds is during the summer. Barely cover the aloe seeds with sand on a tray of cacti soil. Place the tray in an area with bright indirect light with temperatures that stay a constant 70 to 78 degrees Fahrenheit. Keep the seeds moist by misting with water.
Most aloe seeds will germinate in 4 to 16 weeks if the growing conditions are favorable. Some seeds will take up to two years to germinate. This variable germination time and the fact that seeds do not produce a clone of the parent plants, make growing aloe from seed impractical most of the time.
