  • Soak the lemongrass stalk in water for a few hours or overnight. This will help hydrate the stalk and stimulate root growth . You can also cut the stalk into smaller pieces, each with at least one bud, to get more plants .

Once you have prepared your lemongrass stalk, you can plant it in a container and water it regularly. Here is how to do it:

  • Choose a large and shallow container with drainage holes at the bottom. Lemongrass rhizomes grow horizontally, so they need more space to spread out. Fill the container with a well-draining potting mix that is rich in organic matter. You can also add some perlite, vermiculite, or sand to improve the drainage and aeration of the soil.
  • Plant the lemongrass stalk about 2 inches deep in the soil, with the buds facing up. Cover it lightly with soil and water it well. Place the container in a warm and sunny spot, either indoors or outdoors, depending on your climate. Lemongrass prefers temperatures between 60°F and 85°F, and can tolerate some frost if acclimated.
  • Water your lemongrass plant regularly, but not too much or too little. The soil should be moist but not soggy or dry. Check the soil with your finger before watering and adjust accordingly. A general rule is to water once or twice a week during the growing season and less often during the winter.

How to care for and harvest your lemongrass plant

Caring for your lemongrass plant is easy and rewarding. You will see green shoots emerging from the soil in a few weeks, followed by long and slender leaves. You can harvest your lemongrass at any time of the year, depending on how much you need and how big you want it to be. Here are some tips on how to care for and harvest your lemongrass plant:

  • Feed your lemongrass plant with a balanced fertilizer that contains nitrogen, phosphorus, potassium, and micronutrients such as iron, zinc, manganese, etc. You can use organic or synthetic fertilizers, but avoid those that are high in salt or chlorine. Apply fertilizer every two or three months during the growing season and stop during the winter. Follow the instructions on the label for the amount and frequency of application.
  • Prune your lemongrass plant if it becomes too tall or leggy. You can cut off some of the stems and leaves to maintain its shape and size. Avoid pruning more than one-third of the foliage at a time or during the flowering or fruiting season.
  • Protect your lemongrass plant from pests and diseases that can affect its growth and yield. Some of the common problems are aphids, spider mites, mealybugs, scale insects, root rot, leaf spot, etc. You can control them by spraying your plant with water, insecticidal soap, neem oil, or other organic or synthetic remedies.
  • Harvest your lemongrass when it is ready by gently digging up the rhizomes from the soil. You can harvest as much as you need and leave the rest in the soil for later use. You can also harvest the whole plant at once if you want to start over with new roots.
  • Wash and dry your lemongrass rhizomes before using them fresh or storing them for later use. You can peel off the outer layer or leave it on depending on your preference. You can store your fresh lemongrass in a plastic bag in the refrigerator for up to two weeks or in the freezer for up to six months. You can also dry them in a dehydrator or an oven at low temperature for several hours until they are brittle. You can store your dried lemongrass in an airtight container in a cool and dry place for up to a year.
  • Planting lemongrass in pots is a fun and easy way to grow your own fresh and fragrant herb at home. All you need is a lemongrass stalk, a pot, some potting mix, and some basic plant care skills. Remember to choose a healthy stalk, soak it before planting, water it regularly, feed it with a balanced fertilizer, prune it to maintain its shape, protect it from pests and diseases, and harvest it when it is ready. You can use your fresh or dried lemongrass in cooking, tea, oil, vinegar, soap, candles, and more.
