Once I've selected the plants to put in my chams house, how do I prepare them to go in? Do I need to wash off the leaves and the roots and replant them in new soil that is organic and not full of man made plant growth stuff? I found some Hibiscus, Crotons, and Golden Pothos at Wal-mart but they all had little white crystals mixed in the soil so I did not buy them. I am also going to buy some small Ficus trees for my room and let Fiona climb around on them freely. I'm sure that will make her feel happy and more like family than just a pet.
