Why are the leaves curling and turning brown?
Brown leaves are usually the opposite of yellow leaves and typically is a sign of not enough water. Be sure to ensure that the soil beneath your tree is not draining too quickly. When the soil is draining too fast, the root system does not receive the proper amount of moisture that it needs. Also, be sure to check that your tree is not planted on too steep of a slope – this can cause the water to runoff and drain quickly instead of soaking down into the root system.
