Citronella grass, known for its aromatic leaves, is valued for its utility in pest control, with its oil commonly used to repel mosquitoes and other insects. It can be an asset in food forests for its practicality as a natural and non-toxic pest deterrent. With a moderate growth habit and reaching heights of 5-6 feet, citronella grass is suitable for providing both its mosquito-repelling properties and a touch of beauty to the food forest. To cultivate citronella grass successfully, provide well-drained soil, regular watering, and ensure adequate spacing, making it a practical choice to enhance the functionality and comfort of food forests.
