The curry leaf (Murraya koenigii) is a small shrub or tree, growing 12 to 15 feet high with a 10-to-12-foot spread. Native to India, curry leaf is a member of the citrus family. Although the tree blooms in fragrant, white flowers, it is the foliage of the curry leaf tree that holds the most value for growers: curry leaves are commonly used as a seasoning in many Indian dishes. Curry leaf trees are hardy in warmer regions, (USDA zones 9a through 11), but you can grow them in containers in colder regions and move them indoors in the fall. The curry leaf plant, propagated by suckers, root cuttings or seed, is a low-maintenance plant that is available as a seedling in many nurseries.
Grow the curry leaf plant, whether in a container or in the ground, in full sun. The soil should be well drained. The ideal soil for growing the curry leaf plant contains one part peat moss to two parts loam to one part sand.
Water the curry leaf plant when the top 4 inches of soil is dry. Water until the soil is saturated and allow the soil to dry prior to watering again.
Fertilize the curry leaf plant every two weeks from April to September with an organic fertilizer labeled for use on herb plants. Apply the fertilizer at the rate suggested on the label and always water after fertilizing.
Remove leaves from the curry leaf plant by pinching them off as you need them.
