Pink Nepthytis (Arrowhead) Plant Turning Brown
Can you identify the problem with my nepthytis. It is a variety with pink/red tones in the leaves. Some of the leaves have turned brownish and the new leaves are brown before opening. I don’t see any signs of insects. I have had another variety of this plant that I had for many years and never had a problem with it.
The leaves of a pink/red nepthytis are sensitive; they become “bleached” and turn an ugly gray-brown color when placed in the direct sun. Over-fertilizing and using water that has passed through a softener causes salts to build up in the soil and these salts can cause brown leaves. Insufficient humidity around an Arrowhead Plant is another cause of brown leaves.
These are very common plants, especially the green variety, but they are considered poisonous and should be kept away from pets and children. Read more about common houseplants that are poisonous in Don’t Feed Me To Your Cat! A Guide to Poisonous Houseplants.
