Lime

Lime Lime (Citrus aurantifolia) is a small, round citrus fruit known for its tart, acidic flavor and refreshing aroma. The lime tree is an evergreen tree native to Southeast Asia, believed to have originated in Indonesia or Malaysia.

Starting Plants

Lime trees are typically propagated through grafting or from cuttings, as they do not grow true to seed. Grafted trees are usually more disease-resistant and have a shorter time to fruit production. Lime trees can also be grown from seed, but they may take up to 10 years to produce fruit and may not have the same characteristics as the parent tree.

Hardiness

Lime trees are best suited to USDA hardiness zones 9-11, as they are sensitive to cold temperatures. They can tolerate temperatures down to 28°F (-2°C) for short periods, but prolonged exposure to cold can damage or kill the tree.

Plant Size

Lime trees can grow 6-15 feet (1.8-4.5 m) tall and wide, but they can be pruned to maintain a smaller size for easier harvesting and maintenance. Dwarf varieties are also available, which are better suited for container gardening.

Harvesting

Limes are typically ready to harvest 3-4 months after flowering, depending on the variety and climate. Fruits are ripe when they have reached their mature size and have developed a glossy, deep green color. Harvest limes by cutting them off the tree with scissors or a sharp knife, leaving a small portion of the stem attached.

Production

Lime trees can produce fruit year-round in the right conditions, with the main harvest periods occurring in late spring and early fall. Trees typically begin bearing fruit 3-5 years after planting and can continue producing for up to 20 years with proper care.

Seed Harvesting

To harvest lime seeds, remove them from a mature fruit and rinse them thoroughly. Allow the seeds to dry completely before storing them in an airtight container in a cool, dry place.

Common Varieties

Some popular lime varieties include:

• Key Lime (Mexican Lime)
• Persian Lime (Tahiti Lime)
• Kaffir Lime
• Rangpur Lime
• Sweet Lime

Uses as Food

Limes are widely used in cooking and mixology, adding flavor to dishes, sauces, marinades, and cocktails. They are a key ingredient in guacamole, ceviche, and Thai cuisine. Lime juice is also used to make limeade and is a common garnish for beverages. Limes are a rich source of vitamin C and flavonoids.
