Q.Removing a birds nest fern attached to another tree.
I have several birds nest ferns attached to sago palm trunks, a natural occurrence, I didn’t plant them there. I’d like to remove them and wonder how do I do that? I’ve tried prizing one off but it won’t budge. Do I need to cut them away? If so how deep are the roots and will it damage the sago palm?

Do not cut the fern, but simply tease and remove the plant with your hands.
I found a great Blog post that will help you!
