The plant can take in the air you breathe out and then give off the clean air that you breathe in. Aloe vera is popular for its long life as well. Most of the plants can live for around ten years indoors. However, if they are carefully cared for, they can live for over 20 years. Warm and dry air, lots of bright light, regular watering, and protection from pests and diseases will help them live longer. Growing an aloe vera plant at home is very easy! You can buy a plant at a store. Put it in a place with lots of sunlight. Water your plant during the spring, summer and autumn.
