The light lemon flavor of lemongrass is a welcome addition to teas as well as in a variety of recipes. Growing your own lemongrass allows you access to the fresh herb year-round if you plant it in pots. Lemongrass is a perennial plant that goes dormant in the winter due to the cooler temperatures. When planted in pots it can be moved to warmer areas so that it stays green and growing throughout the winter months.
Choose a 10- to 12-inch diameter pot that has drainage holes in the bottom. Use traditional planters, hanging baskets or drill 1/4-inch drainage holes into a recycled container.
Mix one part compost with one part peat moss and one part vermiculite. Fill the pot to within 2 inches of the rim with this potting mix.
Plant the lemongrass transplant into the pot at the same depth it was planted in its nursery pot. Lemongrass is rarely sold as seed so transplants must be purchased from a nursery or garden center.
Water the soil after planting until the excess moisture drains from the bottom of the pot. Water when the top of the soil begins to feel dry, always adding the water until the excess begins draining.
Place potted lemongrass outside in summer in an area that receives at least eight hours of sun a day. Bring it indoors before the first fall frost and place it in a sunny, warm window.
Fertilize lemongrass with a half-strength balanced soluble fertilizer. Fertilize the grass every seven to 10 days to replace the nutrients that are washed out of the pot during watering.
