By following these care tips, you can help your orange trees thrive and produce delicious fruit for years to come.
Managing Citrus Pests and Diseases in North Carolina
While growing oranges in North Carolina can be a rewarding endeavor, it’s important to be aware of the pests and diseases that can affect your trees.
Citrus greening disease, also known as Huanglongbing (HLB), is a serious bacterial disease that can affect citrus trees. It is spread by a tiny, winged insect called the Asian citrus psyllid. Symptoms of citrus greening disease include yellowing leaves, misshapen fruit, and a decline in overall tree health. Unfortunately, there is no cure for this disease, and infected trees eventually die.
To prevent citrus greening disease, it’s important to monitor your trees regularly for signs of the Asian citrus psyllid. If you spot this pest, contact your local agriculture extension office or pest control provider for recommendations on control methods.
Citrus canker is another bacterial disease that affects citrus trees. It causes lesions on leaves, stems, and fruit, leading to defoliation and fruit drop. Citrus canker is highly contagious and can be spread by wind, water, and human activity. Infected trees must be removed and destroyed to prevent the spread of the disease.
To avoid citrus canker, buy only certified disease-free citrus trees and avoid planting them near citrus trees from unknown sources.
Scale insects are common pests that can infest citrus trees. They look like small bumps on the stems and leaves and can cause yellowing and wilting of the foliage. To control scale insects, use horticultural oil or insecticidal soap according to the label instructions.
Spider mites are another common pest that can affect citrus trees. These tiny pests can cause leaf yellowing, stippling, and defoliation. To control spider mites, use a miticide or insecticidal soap according to the label instructions.
By being vigilant about monitoring your trees for pests and diseases, you can help keep your orange grove healthy and productive for years to come.
Harvesting and Storing North Carolina Oranges
