Licorice Plant 101: Growing and Caring for Helichrysum petiolare

Q: Do I really need a grow light, or is my sunny window enough to grow plants indoors?
A window is fine for a low-light houseplant. However, to grow vegetables indoors, start a robust indoor herb garden, or grow any edible plants to grow successfully, you absolutely need a grow light. Windows filter usable light, and winter daylight is too short during the growing season. LED lights are the best tip to give your indoor garden a great start.
Q: My indoor vegetable seedling keeps falling over and dying at the base. What am I doing wrong?
This is "damping off," a fungal disease from overly wet potting soil and poor airflow. To prevent this, ensure your pot has a functional drainage hole, never let the seedling sit in water, and remove humidity domes the moment seeds sprout. A gentle fan nearby also helps.
Q: I live in a very small space. What are the best plants to grow that won't take over my apartment?
For a small garden, focus on vertical growth. An indoor herb garden using a windowsill herb garden planter is perfect. For edible plants, try growing micro varieties of vegetables or leafy greens in a small indoor container. Try easy to grow at home trailing plants like Pothos that hang from the ceiling to save space to grow.
Q: Can I plant the dry mung beans I bought from the grocery store?
A: Yes, you often can! Many home gardeners successfully sprout or plant whole, dried mung beans from the supermarket. However, for the highest germination rates and to ensure the seeds haven't been heat-treated or irradiated (which prevents sprouting), it is best to purchase organic mung beans or seeds specifically packaged for planting and sprouting.
Q: Do mung bean plants need a trellis or support to grow?
A: No. Unlike pole beans that require a tall trellis to climb, mung beans are "bush beans." They grow into upright, self-supporting, bushy plants that typically reach between 24 and 36 inches tall.
Q: Why did my homegrown mung bean sprouts turn green and bitter?
A: Your sprouts were likely exposed to light. When sprouting beans are exposed to sunlight, they begin to produce chlorophyll, which turns the leaves green and creates a bitter taste. To keep your sprouts white, sweet, and crisp, make sure you store your sprouting jar in a completely dark place, like inside a kitchen cabinet, or cover it with a thick, dark towel.
1. Can I grow these plants on a balcony or indoors?
Yes — many of these thrive in containers. Basil, parsley, rosemary, lettuce, strawberries, and jalapeños all do well on a sunny balcony or in bright indoor spots. Make sure containers have drainage holes, use quality potting mix, and place plants where they get enough light for their type. A south-facing window usually works well for herbs grown indoors.
2. How often should I water my beginner garden?
Most beginner plants need consistently moist — not soggy — soil. A deep watering 2 to 3 times per week usually works better than daily shallow watering because it encourages deeper root growth. Stick your finger an inch into the soil; if it feels dry, water. Mulch helps keep soil moisture steady between waterings and reduces how often you need to water overall.
3. Which plants work best in cool seasons versus hot summers?
Cool season crops like lettuce, kale, snap peas, broccoli, cauliflower, and radish do best in spring and fall. Heat-loving plants including basil, cucumber, squash, jalapeños, strawberries, and zinnias thrive through the heat of summer. Matching the plant to the right season makes a huge difference — it is often the single biggest factor in beginner success.

Requirements for Growing Licorice

Soil
These plants thrive in well-draining soil. It's essential to ensure that not too much water is retained, as this can lead to root rot. A mix that includes sand or perlite can help improve drainage. Make sure that the pH is between 6.0 and 7.5 for best results.
Water
While they are relatively drought-resistant, they do require regular watering, especially during the first few days. Once established, you can reduce the frequency, allowing for sufficient drying in between watering sessions.
Temperature and Humidity
These plants prefer warmer temperatures (65-85°F) and can tolerate dry conditions. They do best in mild climates and can handle a bit of neglect when it comes to humidity.
Sunlight
They love sunlight! Place them in a spot where they can receive plenty of direct sunlight throughout the day (approximately 6 to 8 hours). If they're indoors, a sunny window will work well.
Location
These plants are versatile and can thrive in various settings. They look great in hanging baskets, containers, or even as ground cover in garden beds. Their trailing stems make them an excellent choice for adding elegance to any area.
Maintenance Tips

Fertilizer
Licorice plants generally don't need heavy feeding. Use a balanced, slow-release fertilizer once in the spring to give them a good start. Avoid over-fertilizing, as this can lead to leggy growth.
Pruning
Pruning is essential to maintain the shape and encourage healthy growth. Trim back any leggy or overgrown stems to keep the plant looking tidy. Pruning also helps promote fuller growth.
Mulching
Adding a layer of mulch around the base helps retain moisture and keep the ground temperature stable. Organic mulch, such as bark or compost, works well and also adds nutrients to the ground as it decomposes.
Potting and Repotting
If you're using containers, choose a pot that is large enough to accommodate their roots. Repot them every couple of years or when you notice the plant becoming root-bound. When repotting, use fresh potting mix to provide new nutrients.
Overwintering
In colder regions, licorice plants may not survive the winter outdoors. If you live in a colder climate, consider bringing your potted plants indoors before the first frost. Keep them in a cool, bright location and reduce watering to keep them healthy through the winter months.
Common Pests and Diseases

Pests
- Aphids: These small, sap-sucking insects can cause foliage to curl and become distorted. To get rid of aphids, spray the plant with a mixture of diluted down dish soap. Ladybugs, a natural predator of aphids, can also be introduced to control the population.
- Spider Mites: These tiny pests are hard to see but can cause foliage to look speckled or bronzed. If you suspect spider mites, spray the plant with moisture to knock them off and increase humidity around the plant. Insecticidal soap or neem oil can also be effective.
- Whiteflies: These small insects can cause yellowing foliage and a sticky substance on the plant. Use yellow sticky traps to capture whiteflies and spray the plant with insecticidal soap if the infestation is severe.
Diseases
- Root Rot: This occurs when the ground is too wet and poorly draining, leading to the roots rotting. To prevent root rot, make sure the plant is in well-draining ground and avoid overwatering. If you notice yellowing parts and a rotten smell from the ground, remove the affected plant, trim off the rotten roots, and replant in fresh, dry ground.
- Powdery Mildew: This fungal disease appears as a powdery coating. To treat powdery mildew, remove any affected parts and improve air circulation around the plant. A solution of diluted baking soda can also manage the spread.
How to Harvest Licorice

Gathering licorice is simple and rewarding. Wait until your licorice plants are well-established, typically in their second year of development. Choose a sunny day to gather. Carefully dig around the base of the plant to uncover the roots, while being careful not to damage them. Once you've exposed the roots, cut off sections as needed, leaving some roots intact so the plant can continue to thrive. Clean the gathered roots thoroughly and let them dry before use. This method ensures you get the most out of your licorice plants while allowing them to thrive year after year.
Frequently Asked Questions
Q: How often should I water my licorice?
A: Licorice does best when the ground is allowed to become slightly arid between moisture applications. In the early stages of development, keep the ground consistently moist. Once established, dampen less frequently, providing a deep soaking when the top inch of ground feels arid to the touch. It is also helpful to note that the licorice plant benefits from well-draining soil, adequate sunlight, and occasional pruning to maintain its shape and encourage new growth.
Q: What type of soil is best for licorice?
A: Licorice thrives in well-draining ground with good aeration. A sandy or loamy mix with organic matter works well. Avoid heavy clay ground that retains too much moisture, as they can lead to root problems.
Q: Can licorice be placed indoors?
A: Yes, it can be successfully nurtured indoors as long as it receives plenty of light. Place it near a bright window where it can get at least six hours of sunlight each day. Use a well-draining potting mix and ensure the container has drainage holes to prevent moisture from accumulating.
