Hi Nanci , One of the things to consider is how dry your house is and how much time can you devote to watering . most will require daily watering sometimes more than once a day depending on Temps .
Some people use cork slabs , or rough textured wood slabs with no oil in the wood , wild grape vines and cactus skeletons work well .
I use strips of panty hose to tie them to the mount with the roots directly on the mount with a little Spag. over them . gin
