What is the white residue on the leaves of my tree?
Our irrigation system uses well water that is high in calcium.
The white residue in the leaves of your plants is calcium residue. It is not mold or fungus.
This why powdery residue on makes the leaves look unsightly. But it does not cause any damage to your tree.
SOLUTION: Cleaning the leaves with a sponge with dish soap and rinsing it with water will get rid of this residue.
Well water often contains high levels of minerals, such as calcium and magnesium. These minerals can form a white residue on the leaves of plants when the water evaporates. It makes the leaves look unsightly.
