My Aroid has several leaves that are turning white around the edges then the whole leaf turns yellow and wilts. I have two of them facing NW in front of the concrete side of the house. The smaller one is doing fine and is about 4 feet the other is about 5 feet tall. The soil is fairly moist but not too wet. What is wrong? I ive in Hobe Sound, FL.
A number of things could cause those symptoms - can you post some digital pics so I can see what you are describing? If the leaves are positioned such that they get too much sun, that can cause the discoloration. An infestation of spider mites can also cause whitening, then yellowing of the leaves. Look closely and see if you can spot tiny moving dots and fine webbing. If these are present, you have a severe infestation.
