chemicals

I'm moving to a new house in a few weeks and my plan was to have my adult leopard tortoise free range in the backyard. I just found out from the previous owner that they have been using a quarterly lawn company that treats the yard for weeds and fertilizes it. :( How long are these chemicals in...

Hey guys i bought a Opuntia cactus from Home Depot today thinking they were safe for torts... but when i got home i read Home Depot may or may not use chemicals on their plants... Is this true? If not- any recommendations on how to prepair this as food for my little baby Sulcata? Thanks :)
