Everything it needs
9 essentials at a glance
Watering
Creeping Charlie prefers consistently moist soil but can tolerate short periods of dryness.
Water when the top inch of soil feels dry, typically every 1-2 weeks, depending on humidity and temperature. In hotter months, increase frequency to once a week. Signs of over-watering include yellowing leaves and root rot, while under-watering can cause wilting and browning leaf edges.
Light
Creeping Charlie thrives in partial shade but can tolerate full sun if kept adequately watered.
Ideally, it should receive 4-6 hours of indirect sunlight daily. Too much direct sunlight can scorch the leaves, while too little light may result in leggy growth.
Soil
This plant prefers well-draining, loamy soil with a pH range of 6.0 to 7.0.
A mix of potting soil and perlite or sand can enhance drainage. Ensure the pot has drainage holes to prevent waterlogging.
Humidity
Creeping Charlie enjoys moderate humidity levels, ideally between 40-60%.
To increase humidity, mist the leaves regularly or place a humidity tray filled with water near the plant. Signs of low humidity include crispy leaf edges and leaf drop.
Temperature
The ideal temperature range for Creeping Charlie is between 60-75°F (15-24°C).
It is hardy in zones 3-10 and can tolerate light frost. Protect from extreme heat, as temperatures above 85°F (29°C) can stress the plant.
Fertilizing
Use a balanced, water-soluble fertilizer with an NPK ratio of 10-10-10 every 4-6 weeks during the growing season (spring and summer).
Reduce feeding in fall and winter. Signs of nutrient deficiency include yellowing leaves and stunted growth.
Pruning
Prune Creeping Charlie in early spring to promote bushier growth and remove any dead or damaged leaves.
Use clean, sharp scissors or pruning shears. Deadheading is not necessary, but trimming back leggy growth can improve appearance.
Repotting
Repot Creeping Charlie every 1-2 years or when it outgrows its pot.
Signs it needs repotting include roots growing out of the drainage holes or stunted growth. Choose a pot 1-2 inches larger in diameter and follow the same soil recommendations as above.
Propagation
Creeping Charlie can be propagated through stem cuttings or division.
For stem cuttings, take 4-6 inch cuttings in spring or early summer, remove lower leaves, and place them in water or moist soil until roots develop. For division, carefully separate clumps in spring or fall and replant immediately.
When it's unhappy
Yellow leaves
Why it happens
This can be caused by over-watering or nutrient deficiency.
How to fix it
Check the soil moisture and adjust watering frequency. Fertilize if nutrient deficiency is suspected.
Wilting leaves
Why it happens
Under-watering or extreme heat can lead to wilting.
How to fix it
Increase watering frequency and ensure the plant is not exposed to direct sunlight during the hottest part of the day.
Leggy growth
Why it happens
Insufficient light can cause the plant to stretch towards the light source.
How to fix it
Move the plant to a location with more indirect sunlight or supplement with grow lights.
Root rot
Why it happens
Over-watering or poor drainage can lead to root rot.
How to fix it
Allow the soil to dry out before watering again and ensure the pot has adequate drainage.
Pest infestations
Why it happens
Aphids and spider mites may infest the plant, especially in dry conditions.
How to fix it
Inspect regularly and treat infestations with insecticidal soap or neem oil.
Care through the year
Spring
In spring, prune back any dead growth and begin fertilizing every 4-6 weeks to support new growth.
Summer
During summer, ensure consistent moisture and provide some afternoon shade to prevent leaf scorch in hot weather.
Fall
In fall, reduce watering as growth slows and prepare for dormancy. You may also divide the plant if needed.
Winter
In winter, keep the plant in a cool location and reduce watering further, allowing the soil to dry out more between waterings.
Toxicity & Safety
Creeping Charlie is non-toxic to pets and children. It is safe to handle and poses no health risks upon ingestion.
