Causes

Provide a healthy growing environment. Orange trees need full and direct sunlight throughout the day and regular watering. Keep the soil irrigated and ensure that it drains well to prevent fungal problems in standing water. Prune the orange tree annually of any dead or diseased limbs that can cause leaf loss later in the season, or spread disease to the rest of the tree. General orange tree care helps prevent leaf loss.

Effects

Applying pesticides and fungicides controls pest and disease problems. Dormant horticultural oils help kill remaining insect eggs from the previous season. Applying pesticides throughout the rest of the growing season protects the tree from insect damage. Fungicides kill or control fungal spores, preventing disease from attacking and killing the leaves.
