Aloe likes temperature and is afraid of cold. When the temperature drops to 15℃, the growth stops, and when it drops below 0℃, it begins to die. Therefore, it must be planted in greenhouses or indoor potted plants in the northern region. Aloe belongs to tropical and subtropical light-avoiding plants, and its growth needs sufficient sunshine and air. At the same time, aloe is a succulent plant in tropical desert, so it should be kept away from stagnant water, humidity and ventilation.
