What I do is get an umbrella plant (or two depending on its size/ the size of the cage) and dig out about an inch or inch and a half of soil all the way around the pot. Then I get the all natural Super Soil that is in a brown bag and fill that up to where the brim of the pot is and then pack it down a bit, but not so much that it is really hard. Then I rinse off the plant really well and water the plant and leave it out for a day or two in the sun. Then I put it in the chameleons cage. If you are wondering about other things you can do for the plant go to
www.chameleonsonly.com and it has a area that tells you how to clean a plant in detail.
