I'm doing a Lizardmen Diorama set within the jungles of lustria. The base for the Diorama is 300x150mm and I need more or less the entire thing covered in damp soil. I don't know how to do this. There are also going to be troglodon foot-prints set into the soil so I need a material that I'll be able to do this with, though I may make the imprints out of green-stuff and then just put the soil over the top. I'm also looking for a company which sells large exotic trees and exotic plants, like a rainforest sort of look. I also need some astec-y stuff for some Lizardmen ruins.
How would I go about making the floor look like soil?
Where can I buy rainforest-like trees and plants?
Where can I buy Aztec/Lizardmen themed scenery?
