Rough lemon

Rough Lemon

Rough lemon (Citrus jambhiri) is a naturally occurring hybrid species of citrus fruit. It is believed to be a cross between a mandarin orange and a citron. The fruit is larger than a typical lemon and has a thick, bumpy skin, hence the name "Rough lemon".

Origin and Distribution

The rough lemon is thought to have originated in northeastern India, where it is still found growing wild. It has been cultivated in other parts of the world, including Southeast Asia, Australia, and the United States. In the United States, it is primarily grown in Florida and California.

Characteristics

Rough lemons are larger than common lemons, with a diameter of up to 12 cm. The skin is thick and rough, with a bright yellow color. The flesh is juicy and acidic, with a strong lemon flavor. The tree is hardy and can tolerate a range of soil conditions, making it a popular choice for home gardens.

Uses

Rough lemons are used in the same way as other lemons. They can be used in cooking and baking, for their juice, or as a garnish. The zest of the rough lemon can also be used to add flavor to dishes. In addition, the rough lemon is often used as a rootstock for other citrus trees due to its hardiness and resistance to diseases.

Cultivation

Rough lemon trees prefer a sunny location with well-drained soil. They are tolerant of a range of soil types, including sandy, loamy, and clay soils. The trees are also relatively drought-tolerant, but will produce better fruit with regular watering.

Propagation

Rough lemon trees can be propagated by seed or by grafting. Seeds should be planted in a well-draining soil mix and kept moist until germination. Grafting involves attaching a cutting from a rough lemon tree to the rootstock of another citrus tree.

Pests and Diseases

Rough lemon trees are susceptible to a number of pests and diseases, including citrus canker, citrus greening, and various types of root rot. Regular inspection and appropriate treatment can help to keep these problems in check.
