Teresa I am not sure those aloe vera Miracle videos are legitimate. Yes it does work to promote rooting, but some of the results seem over the top. On the other hand every housewife in Maui has a little kitchen window Garden. Where she throws her scrap fruits, and vegetables out the window. They all have a garden which grows where they're thrown, without any aloe vera. Tropical climates can do amazing things. I visited a friend in Maui years ago who had a 20 ft avocado tree lots of Ginger, papaya, and mango growing and a couple of banana trees with ripening bananas as well, outside her kitchen window She told me the 20 foot avocado tree was 2 years old. She said all she did was throw her cooking scraps out the window.
What's normal for a garden can be very different depending on local.
