How to Grow Licorice Plant Outdoors

Licorice plant, scientifically known as Glycyrrhiza glabra, is a perennial herb that is popular for its sweet-flavored roots. It is native to the Mediterranean and parts of Asia but can be grown successfully outdoors in many regions with the right conditions. Growing licorice plant outdoors can be a rewarding experience, as it not only adds beauty to your garden but also provides you with a natural source of flavoring and medicinal properties. In this article, we will discuss the steps to successfully grow licorice plant outdoors.

Step 1: Choose the Right Location

Licorice plant requires a sunny location to thrive. It prefers full sun but can tolerate partial shade if necessary. Ensure that the chosen spot receives at least 6 hours of direct sunlight each day. The soil should be well-draining and rich in organic matter. Licorice plants prefer slightly acidic to neutral soil with a pH level between 6 and 7.

Step 2: Prepare the Soil

Before planting licorice plant outdoors, it is essential to prepare the soil properly. Start by removing any weeds or grass from the planting area. Loosen the soil using a garden fork or tiller to a depth of about 12 inches. Incorporate compost or well-rotted manure into the soil to improve its fertility and drainage.

Step 3: Planting Licorice Plant

Licorice plants can be grown from seeds or root cuttings. If starting from seeds, sow them directly into the prepared soil in early spring when the soil has warmed up. Cover the seeds with a thin layer of soil and keep them consistently moist until germination occurs, which usually takes about 2-3 weeks.

If using root cuttings, dig a hole that is wide enough to accommodate the roots comfortably. Place the root cutting in the hole, making sure that the crown is level with the soil surface. Backfill the hole with soil and gently firm it around the roots. Water the newly planted licorice plant thoroughly.

Step 4: Watering and Maintenance

Licorice plants require regular watering to keep the soil consistently moist but not waterlogged. Water deeply once a week, ensuring that the root zone receives adequate moisture. During periods of prolonged drought or hot weather, increase the frequency of watering to prevent the plants from drying out.

Apply a thick layer of organic mulch around the base of the licorice plant to help retain moisture, suppress weeds, and regulate soil temperature. Avoid mulching directly against the stem to prevent rotting.

Step 5: Fertilization

Licorice plants benefit from regular fertilization to promote healthy growth and enhance root development. Apply a balanced organic fertilizer, such as compost or well-rotted manure, in early spring before new growth appears. Repeat the application every 4-6 weeks during the growing season.

Avoid over-fertilizing, as excessive nitrogen can lead to lush foliage growth at the expense of root development. Follow the recommended dosage on the fertilizer package and water thoroughly after application to prevent burning.

Step 6: Harvesting Licorice Roots

The roots of licorice plants are typically harvested in their second or third year of growth when they have reached a suitable size. To harvest, carefully dig around the root system using a garden fork or shovel, making sure not to damage the roots. Lift the plant from the ground and gently shake off any excess soil.

Choose the larger roots for harvesting, as they contain more flavor and medicinal properties. Cut off a portion of the root system, leaving enough behind for the plant to continue growing. Wash the harvested roots thoroughly and allow them to dry in a well-ventilated area out of direct sunlight.

Step 7: Pruning and Winter Care

Licorice plants benefit from regular pruning to maintain their shape and promote bushier growth. Prune the plants in late winter or early spring before new growth begins. Remove any dead or damaged stems and trim back the remaining branches to encourage new growth.

In regions with cold winters, licorice plants may require protection to survive. Apply a thick layer of mulch around the base of the plant to insulate the roots and protect them from freezing temperatures. You can also cover the plant with a frost cloth or burlap if severe cold is expected.

Conclusion

Growing licorice plant outdoors can be a delightful experience for gardeners who appreciate its beauty and versatility. By following these steps, you can successfully cultivate licorice plants in your garden, providing yourself with a natural source of flavoring and medicinal properties. Enjoy the journey of nurturing this unique herb and reaping its many benefits!
