How often can I harvest Curry Leaf and what yield per acre is realistic?

Once a curry leaf planting is established, you can harvest repeatedly through the year, commonly cutting the leaf at intervals of a few weeks to a couple of months as the plants flush again, giving several harvests a year over the long life of the planting. Leaf yield per acre builds up over the first couple of years as the plants mature and then settles into a steady annual range that varies with spacing, variety, irrigation and management, so plan with a conservative range and confirm locally. The repeated harvests give steady income, and the low per harvest cost is the attraction. Keep the plants well pruned and fed for good flush. Treat any single yield figure as a range that depends on your conditions, and verify with a local grower.
