What is eating my regal elkhorn fern?
Regal Elkhorn Fern (Platycerium grande) faces similar pest threats to other large mounted platycerium species. Scale insects are the main culprit, camouflaging against the brown shield fronds. Mealybugs and spider mites also occur. Its large, antler-like fertile fronds need careful treatment — avoid harsh sprays on the trichome surface.
