Licorice (Liquorice): Your Guide to Grow and Care for it Properly

From its vibrant foliage to its medicinal properties, licorice (liquorice) have become increasingly popular among plant lovers. In this guide, we will delve into the essential tips, tricks, and expert advice to cultivate and care for this versatile herb. You’ll learn about the ideal growing conditions, propagation techniques, and how to maintain the health and vitality of your licorice plant.

Climate and Growing Conditions for Licorice Plant

Licorice plants thrive in warm and humid climates, making them ideal for regions with Mediterranean-like weather. They prefer full sun exposure, although they can tolerate partial shade. The soil should be well-draining, loamy, and slightly acidic, with a pH range between 6.0 and 7.0. Liquorice plants are not frost-tolerant, so if you live in a colder climate, consider growing them in containers that can be moved indoors during winter.

When it comes to temperature, licorice plants prefer daytime temperatures between 70°F and 85°F (21°C and 29°C) and nighttime temperatures between 60°F and 70°F (15°C and 21°C). In areas with high humidity, ensure proper air circulation to prevent fungal diseases.

Licorice plants also require consistent moisture, so regular watering is necessary, especially during dry periods. However, avoid overwatering, as excessive moisture can lead to root rot. Mulching around the plant helps retain moisture and suppress weed growth. Additionally, liquorice plants benefit from a balanced fertilizer application in early spring to promote healthy growth.

Choosing the Right Location for Liquorice Plant

Selecting the right location is crucial for the success of your licorice plants. As mentioned earlier, they prefer full sun exposure, so choose a spot in your garden that receives at least 6 to 8 hours of direct sunlight per day. If you live in a region with scorching summers, partial shade during the hottest part of the day can help protect the plant from heat stress.

Licorice plants have a spreading habit, so ensure there is enough space for them to grow. They can reach a height of up to 3 feet (1 meter) and spread up to 4 feet (1.2 meters). Planting them too close to other plants may lead to competition for nutrients and sunlight, resulting in stunted growth. Therefore, provide adequate spacing of about 2 to 3 feet (60 to 90 centimeters) between licorice plants.


Planting Licorice Plant: Step-by-Step Guide

Now that you have chosen the perfect location for your liquorice plants, it’s time to get your hands dirty and start planting! Follow these step-by-step instructions to ensure successful establishment:

  • Prepare the soil: Before planting, prepare the soil by removing any weeds or debris. Loosen the soil to a depth of about 8 to 10 inches (20 to 25 centimeters) using a garden fork or tiller. Incorporate organic matter, such as compost or well-rotted manure, to improve soil fertility and drainage.
  • Dig the planting hole: Dig a hole that is slightly larger and deeper than the plant’s root ball. The hole should be wide enough to accommodate the plant’s roots without crowding or bending them.
  • Plant the licorice plant: Gently remove the plant from its container, taking care not to damage the roots. Place the plant in the center of the hole and backfill with soil, ensuring that the plant is at the same level as it was in the container. Lightly tamp down the soil to remove air pockets.
  • Water thoroughly: After planting, water the licorice plant thoroughly to settle the soil and provide moisture to the roots. Use a watering can or garden hose with a gentle spray to avoid displacing the soil.
  • Mulch around the plant: Apply a layer of organic mulch around the base of the plant, leaving a small gap around the stem to prevent moisture accumulation. Mulching helps retain moisture, suppress weed growth, and regulate soil temperature.

Remember to water your newly planted liquorice plant regularly to keep the soil evenly moist. Avoid overwatering, as it can lead to root rot. As the plant establishes, you can gradually reduce the frequency of watering, allowing the top inch (2.5 centimeters) of soil to dry out between watering sessions.


Liquorice Plant Care: Watering, Fertilizing, and Pruning

Proper care is essential to ensure the health and vitality of your liquorice plant. Here are some tips for watering, fertilizing, and pruning:

  • Watering: Licorice plants require regular watering to maintain consistent moisture levels. Water deeply, ensuring that the soil is evenly moist but not waterlogged. Monitor the soil moisture regularly and adjust your watering schedule accordingly. During hot and dry periods, you may need to water more frequently.
  • Fertilizing: Licorice plants benefit from a balanced fertilizer application in early spring, just before new growth emerges. Use a slow-release fertilizer or organic compost to provide essential nutrients for healthy growth. Follow the manufacturer’s instructions for the recommended dosage and application method.
  • Pruning: Licorice plants have a bushy growth habit and can become leggy if not pruned regularly. Pruning helps maintain a compact and attractive shape. In early spring, before new growth begins, prune back any dead, damaged, or overgrown branches. You can also pinch back the tips of young stems to encourage branching and promote a fuller appearance.

Additionally, remove any yellow or diseased leaves to prevent the spread of pests and diseases. Regularly inspect your liquorice plant for signs of pest infestation or disease, such as aphids, spider mites, or fungal infections. Promptly address any issues to prevent further damage.

Common Pests and Diseases of Licorice Plant

While licorice plants are relatively resilient, they can still fall victim to certain pests and diseases. Being vigilant and taking preventive measures can help keep your plant healthy. Here are some common pests and diseases to watch out for:

  • Aphids: These small, sap-sucking insects can cause stunted growth and distorted leaves. To control aphids, you can spray a mixture of water and dish soap onto the affected areas. Alternatively, introduce beneficial insects like ladybugs that feed on aphids.
  • Spider mites: These tiny pests can cause yellowing, stippling, and webbing on the leaves. Regularly misting the leaves with water can help deter spider mites. If the infestation is severe, you can use insecticidal soap or horticultural oil.
  • Fungal diseases: Licorice plants are susceptible to fungal diseases, such as root rot and powdery mildew. To prevent these diseases, ensure proper drainage, avoid overwatering, and provide adequate air circulation. If necessary, apply a fungicide according to the manufacturer’s instructions.

Regularly inspect your licorice plant for any signs of pest infestation or disease. Early detection and prompt action can prevent the spread of pests and diseases, ensuring the overall health of your plant.


Propagating Licorice Plant: Methods and Tips

If you want to expand your licorice plant collection or share it with fellow gardening enthusiasts, propagation is the way to go. Licorice plants can be propagated through various methods, including division, stem cuttings, and seed sowing. Here are some tips for successful propagation:

  • Division: In early spring, when the plant is still dormant, carefully dig up the licorice plant and divide the root clump into smaller sections. Ensure that each section has healthy roots and at least one growing point. Replant the divisions in separate containers or directly in the ground. Keep the soil moist and provide the same growing conditions as for mature plants.
  • Stem cuttings: Take 4 to 6-inch (10 to 15-centimeter) stem cuttings from the parent plant in early summer. Remove the lower leaves, leaving only a few at the top. Dip the cut end in rooting hormone and plant it in a well-draining potting mix. Place the cutting in a warm and humid environment, away from direct sunlight. Mist the leaves regularly to maintain humidity. After a few weeks, the cutting should develop roots. Transplant it into a larger container or directly into the garden.
  • Seed sowing: Licorice plants produce seeds that can be collected and sown in late spring or early summer. Soak the seeds in warm water overnight to improve germination. Sow the seeds in a well-draining seed-starting mix, covering them lightly with soil. Keep the soil consistently moist and maintain a warm temperature of around 70°F (21°C). Germination should occur within a few weeks. Once the seedlings have developed a few sets of true leaves, transplant them into individual pots or directly into the garden.

Propagation can be an exciting and rewarding way to expand your licorice plant collection. Experiment with different methods and techniques to find the one that works best for you.
