I am going to use a ficus tree i purchased from the hardware store as my main plant in my Jascksons chameleons's cage. I know about rinsing and repotting with soil that has no ferts or pearlite, but I wasn't sure about soil drainage. I am planning on some pretty heavy watering and am worried that it may be too much water for the plant. Do any of you add anything to your soils to increase drainage? I will cover the top of the soil with rocks so it is not accessible by the cham. I was thinking of maybe using sand and hydroton or maybe some tree fern fiber or charcoal. Any suggestions? Or should i just use plain organic soil with no additives? I'm sorry if this has been covered before. I am useing a tablet and when I try to use the search function it searches all of google instead of just this forum
