Farmers generally sow seedlings in early spring and transplant them, with growth taking roughly 90-120 days before leaves are harvested in batches from bottom to top by leaf position. Harvesting methods include priming (picking lower, middle and upper leaves at different times) and stalk cutting.

After curing, leaves are graded by stalk p...
