Citrus × latifolia (Persian lime)

Cultivating Citrus × latifolia (Persian lime) requires a warm, subtropical to tropical climate, well-drained soil, and proper care. Here are some key steps:

• Climate & Location: Persian lime trees thrive in warm, frost-free regions. They should be planted in full sun, at least 15 to 20 feet away from buildings or other trees.
• Soil Requirements: Well-drained soil is essential to prevent root rot. A mix of sand, loam, and organic matter works best.
• Watering: Newly planted trees should be watered every other day for the first week, then 1-2 times weekly for the first few months. Once established, water when the top 6 inches of soil are dry.
• Fertilization: Young trees should be fertilized every 2-3 months with a balanced fertilizer (e.g., 6-6-6 or 10-10-10). Mature trees need high-nitrogen citrus fertilizer applied annually in spring.
• Temperature Sensitivity: Persian lime trees can tolerate mild cold, but damage occurs below 28°F (-3°C), and the tree may die below 24°F (-4°C).
• Container Growing: If growing in a pot, use a well-draining container and repot as the tree grows. A 16-to-20-gallon container is ideal for mature trees.
