is anthurium indoor plant ?

Question

if indoor what is its soil mixture ?

Answer 1

This plant can only grow outdoors in Zones 10 and higher and, unfortunately, you are in Zone 9a. You'll need to keep your anthurium indoors as a houseplant. Our experts recommend a half and half mixture of potting soil and orchid soil or perlite.
