Everything it needs
9 essentials at a glance
Watering
Ceropegia woodii prefers to dry out between waterings.
Water thoroughly when the top 1-2 inches of soil feel dry, typically every 2-3 weeks during the growing season. In winter, reduce watering to once a month. Signs of over-watering include yellowing leaves and root rot, while under-watering may lead to shriveled leaves.
Light
This plant thrives in bright, indirect light but can tolerate some direct sunlight.
Ideally, it should receive 4-6 hours of light daily. Too little light can cause leggy growth, while too much direct sun can scorch the leaves.
Soil
Ceropegia woodii prefers well-draining soil with a pH of 6.0 to 7.0.
A cactus or succulent potting mix is recommended, or you can create your own by mixing regular potting soil with perlite or sand to enhance drainage.
Humidity
This plant enjoys moderate humidity levels, around 40-60%.
To increase humidity, you can mist the leaves or place a humidifier nearby. Signs of low humidity stress include browning leaf tips and leaf drop.
Temperature
Ceropegia woodii thrives in temperatures between 65-80°F (18-27°C).
It is not frost-tolerant and should be kept above 50°F (10°C). It can tolerate higher temperatures, but prolonged exposure to extreme heat can stress the plant.
Fertilizing
Use a balanced liquid fertilizer with an NPK ratio of 10-10-10, diluted to half strength.
Fertilize every 4-6 weeks during the growing season and refrain from fertilizing in winter. Signs of nutrient deficiency include pale leaves and stunted growth.
Pruning
Prune Ceropegia woodii in spring to maintain its shape and encourage bushier growth.
Use clean, sharp scissors to trim back any leggy stems. Deadheading is not necessary, but removing any dead or yellowing leaves can improve overall appearance.
Repotting
Repot every 1-2 years or when the plant becomes root-bound.
Choose a pot that is 1-2 inches larger in diameter. Signs it needs repotting include roots growing out of the drainage holes and stunted growth. To repot, gently remove the plant from its pot, loosen the roots, and place it in fresh soil.
Propagation
Propagation can be done through stem cuttings or by division.
For stem cuttings, take a 4-6 inch cutting below a node, allow it to callous for a day, then plant it in well-draining soil. Keep the soil slightly moist until roots develop. The best time to propagate is in spring or early summer.
