Citrus trees grow best in warm regions with plenty of sunlight, good drainage, and ample water. The seeds are usually planted in well-draining soil that is enriched with organic matter to promote healthy growth. Once the seedlings have established themselves, they require regular watering and fertilization to promote healthy growth. Citrus trees typically take 3-5 years to reach maturity, and then require pruning and occasional fertilization to maintain their health and shape. They produce fruit once a year, typically during the winter months, and can continue to produce fruit for many years if cared for properly.
