Your stag looks great, I am assuming the terra cotta pot is to another plant????
I have a stag that has been in the same wire pot for 12 years, they do not like to be repotted, they attach themselves "shield fronds" and as they age they are green when young but turn brown and papery as they mature. My father-in-law has one that my mother-in-law received for a gift well over 25 years and in the same wire pot as well. Give it a treat with
peels. They are epiphytes and are slow growing. Excellent care
