Hi! I’ve had this birds nest fern for a couple of years and it was going really strong. Recently there aren’t any new sprouts coming up and the center just seems like it’s dirt and dry. I can see the little nubs but it doesn’t seem like they can grow. I heard that you shouldn’t water directly in the center because it can cause rot but I’m no expert. Any suggestions? This is the only plant I’ve managed to keep alive and don’t want to lose her.
