Citrus trees are fruit-bearing plants belonging to the genus Citrus. They are known for producing popular fruits such as oranges, lemons, limes, and grapefruits. These trees thrive in warm, subtropical to tropical climates and require well-drained soil and plenty of sunlight to grow effectively. Citrus trees are evergreen, meaning they retain their leaves year-round. They typically have fragrant flowers that attract pollinators like bees. The fruits are rich in vitamin C and are widely used in cooking, beverages, and for their juice. Proper care, including regular watering and fertilization, is essential for healthy growth and fruit production.
