I have a couple of Ming aralias about 1 foot in height each. They are a few years old now and one of them isn't doing so well because I tried re-potting it. It has withered and the foliage is now drooping and losing strength. However, for some reason it has begun to produce some kind of resin or gum as there is a clear substance that has formed all over the plant. Many leaves are covered and it looks as though the plant is perspiring. Drops of it also appear in various places around the plant. I took a sample of it and it feels like sap from a tree but can also become hard when almost like dried Elmer's glue.
I was hoping someone could tell me for sure what the substance is or where I could find more information on it. Thanks in advance.
