Aloe vera is easy to grow. Just give it a sunny window or put it outside when it is warm, an occasional drink of water in spring and summer, no water in cold weather and don't let it freeze and it will take off. Keeping them in a big pot helps too, the small plants you buy at a nursery or market are just babies, a mature plant is many times larger. Put them in a large pot and you will have a big plant with plenty of leaves to use.
