Lemongrass is a tropical herb packed with strong citrus flavor. The lemon taste is prized in teas, sauces, and soups. In the garden, lemongrass forms a tall, grassy clump 3-5' tall. Its appearance rivals that of many ornamental grasses and can easily fulfill a similar role in the landscape. Lemongrass thrives in full sun and rich, well-drained soil. Provide a steady supply of moisture for best growth, don’t let lemongrass roots dry out. Start harvesting as soon as plants are 12" tall and stem bases are at least 0.5" thick. Cut stalks at ground level, or hand-pull entire stalks. You want to get the entire swollen base, which resembles a scallion or green onion. If a few roots come up with the stalk, don’t worry, it won’t harm the plant. The edible portion of lemongrass is near the bottom of the stalk. Carefully cut off the grassy top part of the plant; use caution, as this can be razor-sharp at times. Take the lemongrass base and peel the outer fibrous layer to expose the inner white, reedy part for use.
