Q.Pothos leaves getting holes
I have scores of very healthy pothos. I have had them for many years and constantly root them when they get leggy and replant them in same pots to keep them full and lush. About a month ago I noticed about 15 of the plants ( located in several rooms) had a few leaves to over 2 dozen leaves that had brownish look and holes and also looked like something had chewed on them. I am POSITIVE I do not have spider mites, scale, or mealy bugs. There are no caterpillars or anything that I can locate. I have separated these plants and cut off all damaged leaves (using scissors dipped in peroxide.). The newer leaves look brown and shriveled, too. The plants are watered usually once a week, fertilized about every other month, have good drainage and good light. I don’t think they would have flourished over the years if not had excellent care.
But now I am stumped.
Please, what could possibly be my problem?
These are VERY drought tolerant. You should only water these when they are dry. With that being said, what I am seeing is a fungal infection. This can happen when the soil remains damp for too long. With these plants, they are particularly easy to care for and will tolerate a variety of conditions, There are very few plants that can fight off fungal infections. Your best course of action here would be to apply wettable sulfur to all of the soil in the house, then spray the plants with a mixture of rosemary oil, garlice oil or extract, and coconut oil mixed in warm water. This will kill off the infection in the top portion of the plants.
