Hello, I have planted a Pachira Aquatica on a sidewalk space of 40"x16" I'd like to know how deep its roots can grow, I've read these guys can grow up to 68 feet, my main concern is that I have a pair of water pipes at 40 feet below the tree and I don't want the roots to break those pipes. Thanks for all the information you can provide. Sorry for my english, not my main language.
