What Sets Creeping Charlie Apart?

Creeping Charlie Care Guide

To ensure your Creeping Charlie plant thrives, it’s important to provide it with the right conditions. Let’s delve into the essential aspects of caring for this tropical beauty.


In its natural habitat, Creeping Charlie grows under the protective canopy of trees in the rainforest. It thrives with filtered light or semi-shade, receiving between 2,500 to 10,000 lux of light. Most homes can easily meet these light requirements without the need for supplemental lighting. Placing your Creeping Charlie in a north or east-facing window will provide sufficient daily light without exposing it to the harsh afternoon sun. If you choose to keep it in a south or west-facing room, ensure it is several feet away from the windows to avoid direct sunlight.


In the tropical rainforest, Creeping Charlie enjoys consistently moist but well-drained soil. To replicate its natural environment, water your plant when the top inch of the soil has dried out. Depending on your home’s temperature and humidity, this may be as often as several times a week. Use a narrow-spout watering can to direct water onto the soil, avoiding wetting the leaves. Water slowly to allow the soil to fully moisten, and allow any excess water to drain out before placing the pot back in its saucer.

Creeping Charlie thrives in temperatures ranging from 65 to 80ºF (18 to 27ºC). It prefers consistently warm temperatures akin to its tropical rainforest origins. During winter, the low end of this temperature range can be easily maintained in the average heated home. However, higher temperatures may not always be attainable. If you want to pamper your Creeping Charlie in the summer, consider placing it in a shady spot on your patio. Avoid exposing it to temperatures below 50°F (10°C), as it has limited cold tolerance. Frost can be fatal to this tropical beauty.


The ideal humidity for Creeping Charlie is around 50%, although it can tolerate humidity levels ranging from 40-60%. If your home’s humidity level doesn’t meet these requirements, there are a few options to increase humidity. You can mist your Creeping Charlie daily using distilled or rainwater. Alternatively, place the plant on a pebble-lined tray filled with water, ensuring the pot remains above the water level. Lastly, a small humidifier can be a great investment, especially if you have multiple tropical plants that can be grouped together.


While Creeping Charlie requires consistently moist soil, it cannot survive in waterlogged conditions. The soil should hold a moderate amount of moisture while allowing excess water to drain. A pH level of 6-7.5, mildly acidic to neutral, is ideal for this plant. If you prefer a ready-mixed soil, look for an African Violet mix that meets these requirements. Alternatively, you can create your own by using a standard peat-based mix and adding perlite and well-rotted compost.


To keep your Creeping Charlie’s foliage lush and healthy, it’s essential to fertilize it throughout the growing season. If you added compost or slow-release fertilizer during repotting, you don’t need to fertilize again until the next repotting session. Look for a balanced fertilizer ratio of 10-10-10 or 3-1-2 for optimal results. Liquid houseplant fertilizer is convenient to use—dilute it to half strength and apply right after watering to ensure proper absorption.


Creeping Charlie is a fast-growing perennial that may require repotting every 2-3 years. Rather than adhering to a strict schedule, keep an eye on the plant’s growth to determine when repotting is necessary. If you notice roots emerging from the drainage holes or the roots completely engulfing the soil, it’s time for repotting. Creeping Charlie prefers slightly cramped conditions, so only go up one pot size or at most 2 inches. Ensure the pot has good drainage holes, and always use fresh potting soil when repotting.

As a fast-growing plant, Creeping Charlie may require occasional pruning to maintain an attractive shape. Remove any dead or damaged leaves immediately by cutting the leaf stem close to its point of attachment. You can also trim any stems that deviate from your preferred direction or pinch off the growing tips to encourage bushier lateral growth. Pruning can be done using your thumbnail or sharp, sterilized scissors.


Propagating Creeping Charlie is relatively easy and can be done through stem cuttings or root division. For stem cuttings, take healthy stems with several leaves and cut them with sharp, sterilized scissors. Leave a couple of leaves at the tip and place the stems in a tray with moistened peat moss or a jar of water. Cover them with a plastic bag to maintain a humid atmosphere, and keep them in a warm, well-lit area. Within a month, you should have rooted cuttings. Alternatively, during repotting, divide the roots to create separate clumps and pot each one up.

Common Problems of Creeping Charlie

While Creeping Charlie is generally a resilient plant, it’s important to be aware of potential problems. By paying attention to its preferred growing conditions, you can prevent most issues. Keep a close eye on the plant’s leaves to identify any problems early on.


While Creeping Charlie is not heavily targeted by pests, some insects may feed on its succulent leaves. Spider mites can leave small white or yellow spots on the leaves, while whiteflies congregate under the leaves. To get rid of these pests, wash the plant thoroughly with a handheld shower or sink nozzle. Mealybugs and their eggs, resembling puffs of cotton, can be wiped off with rubbing alcohol. To prevent further infestations, spray with insecticidal soap once a month.


Overwatering can lead to bacterial or fungal diseases in Creeping Charlie. Bacterial leaf spot, characterized by small, saturated spots on the leaves, can be eliminated by cutting off affected leaves and using a copper fungicide. Root rot, a fungal disease resulting from waterlogged soil, causes yellowing leaves and mushy stems. To combat root rot, remove the plant from its pot, trim blackened roots and affected foliage, repot it in fresh, well-draining soil, and reduce watering frequency.

Growing Problems

Most growing problems with Creeping Charlie stem from inadequate growing conditions, resulting in a sickly plant. If you notice browning or blackening of leaves, it may indicate excessive direct light. Move the plant to a shadier area or use a curtain to filter the light. Drooping leaves could be a sign of overwatering or underwatering. Check the moisture level in the soil and adjust accordingly.

Toxicity of Creeping Charlie

One of the remarkable qualities of Creeping Charlie is its non-toxic nature. It is safe for both humans and pets, including cats, dogs, and rabbits. However, it’s best to discourage anyone, including your furry friends, from munching on the foliage. While there are no toxic substances or skin irritants, it’s always better to err on the side of caution. Keep your Creeping Charlie out of reach, especially if you have curious children or mischievous pets.

Creeping Charlie’s Beautiful Appearance

When it comes to aesthetics, Creeping Charlie does not disappoint. Its evergreen leaves add a fresh tropical touch to any space throughout the year. The bright green foliage boasts a crinkly texture and a glossy surface, with sunken veins that provide a three-dimensional appearance. Each rounded leaf measures approximately 1.5 to 2 inches in length, featuring a distinctive scalloped edge. The petioles, supporting the leaves, are short and may be yellow-green or reddish. Creeping Charlie has an attractive trailing habit, making it perfect for hanging baskets or placed on high shelves.

Suggested Uses for Creeping Charlie

Finding the perfect spot indoors for your Creeping Charlie is a breeze. Its compact size and trailing growth make it an excellent choice for hanging baskets, where its tendrils can gracefully spill down. You can also create a living screen between different areas of a room using a row of planters. Moving your Creeping Charlie outdoors during the summer months allows you to create a tropical garden. However, exercise caution if you live in a non-tropical climate, as Creeping Charlie can quickly become an invasive weed.
