- Geranium oil is a natural, eco-friendly option for pest control in organic gardening.
- It repels pests like aphids, offers antifungal and antibacterial protection, and attracts pollinators like bees.
- Safe for plants and the environment, geranium oil is an effective alternative to chemical pesticides.
How Geranium Oil Works in the Garden
The oil contains active compounds like citronellol and geraniol, which are known for their strong antifungal, antibacterial, and insect-repelling effects.
When applied to plants, geranium oil forms a protective barrier that repels common pests such as aphids, whiteflies, and spider mites. These pests are deterred by the strong scent and chemical composition of the oil, which disrupts their ability to feed on plants. Unlike synthetic pesticides, geranium oil does not harm beneficial insects, allowing pollinators like bees and butterflies to thrive in the garden.
In addition to pest control, geranium oil also helps prevent fungal infections. Its antifungal properties inhibit the growth of common garden fungi, such as powdery mildew and botrytis, which can damage or destroy plants. By applying a diluted solution of geranium oil to the leaves and stems, gardeners can create a hostile environment for fungi and bacteria, reducing the risk of disease.
Moreover, geranium oil can enhance overall plant health by boosting the plant’s natural defenses. Regular use of the oil can lead to stronger, more resilient plants that are better equipped to withstand environmental stressors.
