Galium circaezans, common name licorice bedstraw or wild licorice, is a plant species in the family Rubiaceae. It is native to the eastern half of the United States from the Great Plains to the Atlantic, plus Quebec and Ontario. There are also a few isolated populations in Washington state, probably adventive.
Licorice bedstraw is fairly disease-resistant and usually does not suffer from many ailments. That said, it can be vulnerable to pests or diseases present in its environment. These issues are typically mild. In terms of care, the plant needs moderate maintenance. It should be pruned regularly to maintain a neat appearance and support healthy growth. Fertilizing can also help encourage flowering. Licorice bedstraw is suitable for anyone with an outdoor area, such as a garden or patio, and does not require extensive gardening experience. It may demand more attention when grown indoors.
How to keep Galium Circaezans.
Light
Licorice bedstraw grows best with moderate sunlight, which supports healthy development. It can endure a total lack of sun, although that may slow its growth. Because it comes from habitats with naturally dappled light, intense sun can stress the plant, while too little light may cause stunted growth.
Water
Licorice bedstraw, which comes from temperate regions, thrives best in environments with moderate moisture. For optimal growth, it should be watered weekly and mulched to help retain moisture. When grown outdoors, this plant is hardy and can easily adapt to seasonal rainfall.
Temperature
Licorice bedstraw is indigenous to temperate climates and prefers cooler temperatures ranging from 41 to 90 °F (5 to 32 ℃). To promote optimal growth, it is advisable to adjust temperatures according to seasonal changes.
Fertilizer
Generally, a single fertilizer application in spring is enough for Licorice bedstraw, but additional feedings can maximize growth. Feed it every month to six weeks. Fertilization improves the leaves' appearance and function, helping them keep an even color and a healthy texture. It also encourages root development and nutrient uptake for long-term plant health.
Pruning
Licorice bedstraw is characterized by its delicate stems and small, star-shaped flowers. To promote growth and maintain its shape, prune it in early spring by removing any weak stems just above the leaf nodes. It's best to perform light and regular trims, as heavy pruning should be avoided. Always use clean tools to prevent the spread of disease. For additional guidance, consult reliable sources.

Reader questions.
How should I water my Licorice bedstraw plant?
To properly water the Licorice bedstraw, it is recommended to use filtered water at room temperature. Tap water may contain harmful particles, hence filtered water is preferred. The plant is accustomed to warm conditions, so using cold water may shock it. It is also advisable to avoid overhead watering to prevent issues with the foliage. Instead, gently soak the soil with the filtered room temperature water until it is fully saturated. This helps enrich the roots and supports their growth and nutrient absorption.
What are the sunlight requirements for Licorice Bedstraw?
Licorice Bedstraw thrives in conditions that provide moderate sunlight, requiring about 3-6 hours of sunlight daily. It originates from environments with dappled light, therefore, while it can tolerate a complete absence of sunlight, its growth may be slowed. Excessive sunlight can stress the plant, and insufficient sunlight can lead to stunted growth. It's important to watch how sunlight moves through your garden to find spots that offer a balance of light and shade to ensure the plant's happiness.
What is the native climate of Licorice bedstraw and its preferred temperature range?
Licorice bedstraw, botanically known as Galium circaezans, is native to temperate climatic conditions and thrives in cooler temperature ranges between 41 to 90 °F (5 to 32 °C). Adjusting the temperature based on seasonal variations is recommended to facilitate optimal growth.
What should I do if I give my Licorice bedstraw too much water or too little water?
Both overwatering and underwatering can harm the health of your Licorice bedstraw, but overwatering is more common. When it's overwatered, the stems and leaves may wilt and turn yellow. Over time, overwatering can also cause root rot, mold, and mildew, which can kill the plant. Underwatering is less likely for the Licorice bedstraw because it can tolerate drought fairly well. However, it can still happen, and when it does, the leaves become brittle and brown. It's important to recognize the signs of overwatering early when taking care of your Licorice bedstraw. Some diseases caused by overwatering, like root rot, may not be fixable if you wait too long. If you notice early signs, reduce your watering immediately. Also, check the quality of the soil where the Licorice bedstraw is growing. If it drains poorly, replace it with a loose, well-draining potting mix. If you see signs of underwatering, simply water more regularly until the signs go away.
How can artificial lighting support Licorice Bedstraw indoor growth?
For indoor Licorice Bedstraw plants, it's crucial to provide adequate lighting for optimal growth, especially in conditions of insufficient natural sunlight, like during winter or in less sunny spaces. Artificial lights can be a vital solution, promoting faster, healthier growth. LED lights are recommended as they can mimic specific wavelengths needed by the plant. Full sun plants require 30-50W/sq ft of light, partial sun plants need 20-30W/sq ft, and full shade plants need 10-20W/sq ft. The artificial light should be placed 12-36 inches above the plant for about 8-12 hours a day to mimic natural daylight hours.
Does Licorice bedstraw need special frost protection measures during winter?
Licorice bedstraw exhibits strong cold resistance and usually does not require special frost protection measures. However, if winter temperatures are expected to drop below -30°C, it is important to provide cold protection. This can involve covering the plant with soil or straw, and before the first freeze in autumn, it is advisable to water the plant abundantly to keep the soil moist and prevent drought and water scarcity during winter and early spring.
How frequently should I water my Licorice bedstraw?
If your Licorice bedstraw plant is in a pot, the most precise way to determine if it needs water is by checking the moisture level of the soil. Simply stick your finger into the soil and if the top two to three inches are dry, it's time to water it. If you're growing the Licorice bedstraw outdoors in the ground, you can also use this method. Once the first few inches of soil are dry, it's time to water the plant. Typically, during spring and early fall, watering once a week using this method is sufficient. However, when extremely hot weather arrives, you may need to water it twice or more per week. Keep in mind that mature and well-established Licorice bedstraw plants have a remarkable ability to withstand drought.
What are the symptoms of inappropriate light exposure in Licorice Bedstraw?
Symptoms of insufficient light in Licorice Bedstraw include smaller new leaves, leggy or sparse growth, faster leaf drop, slower or no new growth, and lighter-colored or irregularly colored new leaves. Excessive sunlight can cause chlorosis (leaves turning yellow), sunscald, leaf curling, wilting, and leaf scorching. These symptoms indicate the plant's struggle with either too much or too little light, impacting its ability to photosynthesize and overall health.
How does low temperature affect Licorice bedstraw and what are the solutions?
While Licorice bedstraw is cold-tolerant and thrives best above 5°C, it should be kept above -25°C during winter to avoid damage. Temperatures below -30°C may not show immediate changes, but there could be a decrease in sprouting or no sprouting at all come springtime. The solution is to remove any parts that fail to sprout in spring.
How much water does my Licorice bedstraw plant need?
To properly water your Licorice bedstraw, ensure that the top two to three inches of soil are dry. Give the plant a thorough watering, making sure to fully saturate the soil. The amount of water should be enough to cause excess water to drain out of the pot's holes. If you don't see any excess water draining, you may not have watered enough. However, be careful not to let water accumulate in the soil, as this can harm the plant. On the other hand, if water doesn't drain properly, it may indicate poorly draining soil, which is harmful to the plant and should be avoided. If the plant is outdoors, one inch of rain per week should be sufficient.
What solutions can help Licorice Bedstraw receive optimal light?
To ensure Licorice Bedstraw receives optimal light, gradually shift plants to sunnier spots weekly until they get 3-6 hours of direct sunlight daily. For indoor plants that are large or hard to move, consider supplementing light with desk or ceiling lamps for at least 8 hours daily, or invest in professional grow lights. Outdoors, move plants gradually to sunnier locations to prevent sunburn. Minimize obstructions to sunlight by pruning or relocating plants to areas with better light exposure. Transplant smaller plants during their dormant period to spots with ample sunlight and good drainage. Note that parts of the plant damaged by poor light may not recover, but new growth should be healthy with improved light conditions.
How does high temperature affect Licorice bedstraw and what are the solutions?
During summer, it is important to keep Licorice bedstraw below 32°C to avoid stress from high temperatures. Exceeding 35°C can cause leaves to lighten in color, become prone to curling, susceptible to sunburn, and in severe cases, the plant may wilt and become dry. Solutions include trimming away sunburned and dried-up parts, moving the plant to a shaded location or using a shade cloth to protect it from midday and afternoon sun, and watering the plant in the morning and evening to keep the soil moist.
