If you’re growing your own lemongrass, knowing the right way to harvest it will help you get the freshest flavor and encourage your plant to grow even stronger. When done properly, harvesting lemongrass is quick, simple, and incredibly rewarding. The key is to cut the stalks at the base once they’re thick, firm, and at least ½ inch wide. Regular harvesting not only gives you fresh, fragrant lemongrass for teas, soups, and marinades—it also boosts new growth and keeps your plant thriving all season long.
