Small Oranges: Causes and Solutions
Introduction
Orange trees are beautiful and fruitful additions to any garden. However, sometimes orange trees produce small fruit, which can be disappointing for gardeners. This article explores the potential causes of small fruit on orange trees and provides solutions to help you grow healthy, full-sized oranges.
Causes of Small Fruit on Orange Trees
- Nutrient Stress: Orange trees need essential nutrients like zinc to thrive. A deficiency in zinc can lead to small, discolored fruit.
- Water Stress: Inadequate or improper watering can stress orange trees and result in small fruit. Even daily watering may not be enough if the entire root system is not irrigated.
- Insect Pests: Citrus rust mites, leafhoppers, and melon aphids are insect pests that can damage orange fruit, causing it to be small and misshapen.
- Diseases: Stubborn disease and tristeza disease complex are two diseases that can cause small fruit on orange trees. These diseases are spread by insect pests.

Nutrient Stress:
- Apply a micronutrient spray containing zinc, iron, and manganese in spring and late summer.
Water Stress:

Insect Pests:

Diseases:
