Q.ficus trees
My tree has white bugs on it and leaves are droppping.
Is this a new tree, or have you recently moved it? It looks very full of leaves, and it has to get rid of some of them because it doesn't have enough light for all of them. You can trim out the leafy areas in the center of the tree, that should stop the dropping leaves problem. The white bugs would be mealy bugs; you can spray them with a home made mixture to get rid of them. Just be sure to spray at weekly intervals for 4 weeks, and spray up onto the bottoms of the leaves, and along the branches. https://www.gardeningknowhow.com/plant-problems/pests/mealybugs-white-residue-on-plants-leaves.htm
