Q.lime plant film on leaves
We have a lime tree in 15 gallon pot and other in 3″ pots, and the leaves have a glossy film on them which is curling the leaves. What is the cure? I know you know the cause.

This is a sign of a pest infestation. The glossy film is honeydew. Check the undersides of leaves and where the stems meet. There are several that it could be and, fortunately, they are all treated the same way.
Treat the plant with a pesticide. I personally like neem oil, as it is safe for people and pets. Here is more info on it: https://www.gardeningknowhow.com/plant-problems/pests/pesticides/neem-oil-uses.htm
