How to Grow Licorice Plant Indoors

Licorice plants, also known as Glycyrrhiza glabra, are not only known for their sweet taste but also for their medicinal properties. These plants have been used for centuries in traditional herbal medicine due to their anti-inflammatory and immune-boosting properties. While licorice plants are commonly grown outdoors, it is also possible to grow them indoors, allowing you to enjoy the benefits of this versatile plant year-round. In this article, we will explore the steps to successfully grow licorice plants indoors.

Choosing the Right Variety

Licorice plants come in different varieties, and it is important to choose the right one when growing them indoors. The most common variety is Glycyrrhiza glabra, which is typically used for its roots. However, there are other varieties, such as Glycyrrhiza uralensis and Glycyrrhiza inflata, that can be grown indoors for their ornamental value.

If you are interested in growing licorice plants primarily for their medicinal properties, it is recommended to choose the Glycyrrhiza glabra variety. On the other hand, if you simply want to add a touch of greenery to your indoor space, any licorice plant variety will do.

Providing the Right Conditions

Licorice plants thrive in warm climates and require plenty of sunlight. As such, it is important to place your indoor licorice plant in a location that receives at least 6-8 hours of direct sunlight each day. A south-facing window or a spot near a sunny balcony would be ideal.

In addition to sunlight, licorice plants prefer a temperature range of 60-80°F (15-27°C). Avoid placing your plant near drafts or extreme temperature changes, as this can stress the plant and negatively affect its growth.

Choosing the Right Pot and Soil

When growing licorice plants indoors, it is crucial to choose the right pot and soil. Licorice plants have deep taproots, so opt for a pot with good drainage and a depth of at least 12 inches. This will allow the roots to grow freely.

For the soil, a well-draining potting mix is essential. A mix of equal parts perlite, peat moss, and sand is ideal for licorice plant growth. This ensures that excess water can drain out easily, preventing root rot.

Watering and Fertilizing

Proper watering is important for the healthy growth of your licorice plant. Allow the top inch or two of soil to dry out between waterings, and then thoroughly water the plant until water runs out of the drainage holes. Be careful not to overwater, as this can lead to root rot.

During the growing season, which typically occurs from spring to early fall, you can fertilize your licorice plant every two weeks using a balanced liquid fertilizer. However, during the dormant season, reduce fertilization to once a month or stop altogether.

Pruning and Propagation

Pruning your licorice plant is essential for maintaining its shape and promoting healthy growth. Regularly trim back any dead or damaged leaves, as well as any leggy growth. This will encourage bushier growth and prevent the plant from becoming too unruly.

Propagation of licorice plants can be done through root cuttings. In early spring or fall, carefully dig up a mature plant and cut off a 4-6 inch section of the root. Plant this section in a separate pot filled with well-draining soil and keep it moist until new growth appears.

Dealing with Pests and Diseases

Like any other indoor plant, licorice plants are susceptible to pests and diseases. The most common pests that can affect licorice plants include aphids, spider mites, and whiteflies. Regularly inspect your plant for any signs of infestation, such as yellowing leaves or webbing. If pests are present, treat the plant with an organic insecticidal soap.

Licorice plants can also be prone to root rot if overwatered or if the soil does not drain properly. To prevent this, ensure that your licorice plant is potted in well-draining soil and that excess water can freely flow out through the drainage holes.

Harvesting and Using Licorice

If you are growing licorice plants for their roots, you can harvest them after two to three years of growth. Carefully dig up the plant and cut off the desired amount of roots. Rinse them thoroughly and allow them to dry in a well-ventilated area for several weeks. Once dry, the roots can be used to make herbal teas or tinctures.

It is important to note that licorice roots are very potent and should be used sparingly. Consult with a herbalist or healthcare professional for appropriate dosage recommendations.

Final Thoughts

Growing licorice plants indoors can be a rewarding experience, allowing you to enjoy the benefits of this versatile plant all year round. By providing the right conditions, choosing the right variety, and following proper care techniques, you can successfully grow licorice plants indoors and reap their medicinal or aesthetic benefits. So why not bring a touch of greenery and natural healing into your home by growing your own licorice plant?
