Growing navel oranges can be a rewarding experience, but pests such as aphids, citrus leaf miners, and spider mites often pose challenges. One effective organic method to protect your citrus trees is companion planting. This technique involves planting specific plants nearby to naturally repel pests and promote healthy growth.
Understanding Companion Planting for Citrus Trees
Companion planting leverages the natural properties of certain plants to create a pest-resistant environment. For navel oranges, selecting the right companion plants can reduce the need for chemical pesticides and enhance overall tree health.
Best Companion Plants for Navel Oranges

- Basil: This herb deters thrips, mosquitoes, and certain beetles.
- Chives: Their aroma helps keep away aphids and other soft-bodied pests.
- Lavender: Repels moths, fleas, and some beetles while attracting beneficial insects.
- Petunias: These flowers deter aphids, tomato hornworms, and beetles.
Plants to Avoid Near Navel Oranges
- Mint: While aromatic, mint can become invasive and compete with citrus roots.
- Fennel: Known to attract pests that can harm citrus trees.
- Brassicas (e.g., cabbage, broccoli): Can attract pests that may also target citrus plants.
