Everything it needs
9 essentials at a glance
Watering
The Lipstick Plant prefers to be kept slightly moist, so water it when the top inch of soil feels dry.
During the growing season (spring and summer), water every 1-2 weeks, adjusting frequency based on humidity levels. In fall and winter, reduce watering to once every 2-3 weeks. Signs of over-watering include yellowing leaves and root rot, while under-watering may cause leaf drop and wilting.
Light
Aeschynanthus radicans thrives in bright, indirect light but can tolerate some direct morning sun.
Ideally, it should receive 6-8 hours of light daily. Too much direct sunlight can scorch the leaves, while too little light can hinder blooming and cause leggy growth.
Soil
This plant prefers a well-draining potting mix, ideally one that contains peat, perlite, and orchid bark.
A pH range of 5.5 to 6.5 is optimal. Ensure that the pot has drainage holes to prevent water accumulation, which can lead to root rot.
Humidity
Lipstick Plants enjoy high humidity levels of 50% or more.
To increase humidity, consider using a pebble tray with water or a humidifier. If humidity is too low, you may notice leaf curling or browning tips, indicating stress.
Temperature
The ideal temperature range for Aeschynanthus radicans is between 65-80°F (18-27°C).
It is not frost-tolerant and should be kept in a warm environment, ideally in USDA hardiness zones 10-12. Protect it from cold drafts and extreme heat.
Fertilizing
Use a balanced liquid fertilizer with an NPK ratio of 20-20-20 every 4-6 weeks during the growing season.
In fall and winter, reduce feeding to once every 2-3 months. Signs of nutrient deficiency include yellowing leaves and poor growth.
Pruning
Prune the Lipstick Plant in early spring to promote bushier growth and remove any dead or damaged leaves.
Use clean, sharp scissors or pruning shears. Deadheading spent flowers can encourage more blooms and maintain a tidy appearance.
Repotting
Repot every 1-2 years or when the roots outgrow the 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 refresh the potting mix during the process. Gently remove the plant, loosen the roots, and place it in the new pot with fresh soil.
Propagation
Propagation can be done through stem cuttings or division.
For stem cuttings, take a 4-6 inch cutting below a node, remove the lower leaves, and place it in water or a moist potting mix. Keep it warm and humid until roots develop, usually within 2-4 weeks. Division can be done during repotting in spring.
When it's unhappy
Yellow leaves
Why it happens
This can be caused by over-watering or insufficient light.
How to fix it
Check the soil moisture and adjust watering frequency. Move the plant to a brighter location if necessary.
Leaf drop
Why it happens
Leaf drop may occur due to sudden temperature changes or under-watering.
How to fix it
Maintain consistent temperatures and ensure the soil is kept slightly moist.
Leggy growth
Why it happens
Insufficient light can lead to leggy growth as the plant stretches towards the light.
How to fix it
Move the plant to a brighter location to encourage bushier growth.
Root rot
Why it happens
Over-watering and poor drainage can lead to root rot.
How to fix it
Ensure proper drainage and allow the soil to dry slightly between waterings.
Browning leaf tips
Why it happens
Low humidity levels can cause the leaf tips to brown.
How to fix it
Increase humidity around the plant using a pebble tray or humidifier.
Care through the year
Spring
In spring, increase watering frequency as the plant begins to actively grow. Fertilize every 4-6 weeks and consider repotting if necessary.
Summer
During summer, ensure the plant receives bright, indirect light and maintain consistent watering. Monitor humidity levels and mist the plant if needed.
Fall
In fall, gradually reduce watering as the plant's growth slows. Continue to fertilize every 6-8 weeks until late fall.
Winter
In winter, water less frequently, allowing the soil to dry out more between waterings. Keep the plant in a warm location away from drafts.
Toxicity & Safety
Aeschynanthus radicans is non-toxic to pets and children, making it a safe choice for households. However, ingestion of large quantities may cause mild gastrointestinal upset.
