I have three tall Dracaena Marginatas together in a 15" pot. I wanted to get a ground covering for them, Creeping Fig was recommended to me. So I planted a couple, along with some nice stones. Now I've just read that Creeping Fig can be harmful to wood structures and am worried that it'll hurt my Dracaena. They look really nice together, but if they're not compatible, I'd like to get the vines out now before they really take root. Does anyone know if the vines will damage the larger plant?
