Persian Lime Tree

Persian Lime Tree Care

Citrus × Latifolia

What is the plant

The tree is nearly thornless. The fruit is about 6 cm (2.4 in) in diameter, often with slightly nippled ends, and is usually sold while green, although it yellows as it reaches full ripeness. It is also widely available dried, as it is often used this way in Persian cuisine. It is larger, thicker-skinned, with less intense citrus aromatics than the key lime (Citrus aurantifolia). The advantages of the Persian lime in commercial agriculture compared to the key lime are the larger size, absence of seeds, hardiness, absence of thorns on the bushes, and longer fruit shelf life. They are less acidic than key limes and do not have the bitterness that lends to the key lime's unique flavor.

How to Care for the Plant

Water
Water is of primary importance to your potted lime tree and is gauged by the size of the tree and temperatures. Reduce watering prior to winter to avoid the possibility of stimulating growth that may become damaged in cooler temps. Overwatering can become an issue, but don’t let the tree dry out completely! Allow the upper inch (3 cm.) of the soil to dry out before watering.
Pruning
Prune your container grown lime trees. Watch for any suckers that form and immediately prune them, not only to maintain the shape of the tree but to keep the growth compact and promote better fruit production. Thin branches to 4-6 inches (10-15 cm.) apart for fewer but larger fruit set, in the latter part of winter.
Fertilizer
Fertilize the lime tree monthly until midsummer, and never after July.
