What is the fastest way to pick mint leaves?
How quickly do mint leaves regrow?
From seeding to maturity, mint takes about 90 days. This means that it will achieve its full height, generally of 1 to 2 feet, and it will be ready to harvest. At this point you can cut mint down to 1 inch above the soil, and it will regrow to harvest height again in a month and a half or so.
