Lisa--Happy Holidays to you and yours!!!
Rooting Epis is easy. They are like succulents.
Take a piece of it--and shove it in a pot of soil. Then wait.
No need to use rooting hormones. Just a Pro Mix type of soil.
Do mind the nodes so you get at least one under the potting mix.
Do not water much--if any. Put near a window--and dribble a smidgen of water
on it once in a while.
They will root in a matter of weeks. Easy-Peezy!...
Best to you in the new Year!! Gita
