Everything it needs
9 essentials at a glance
Watering
Houttuynia cordata prefers consistently moist soil, so water it thoroughly when the top inch of soil feels dry.
During the growing season (spring and summer), water every 1-2 weeks, ensuring the soil does not dry out completely. In fall and winter, reduce watering to every 2-3 weeks. Signs of over-watering include yellowing leaves and root rot, while under-watering may cause wilting and leaf drop.
Light
This plant thrives in partial shade to full sun, ideally receiving 4-6 hours of direct sunlight daily.
In hotter climates, it benefits from some afternoon shade to prevent leaf scorch. It can tolerate light shade but may become leggy if not provided with enough light.
Soil
Houttuynia cordata prefers well-draining, rich, loamy soil with a pH range of 6.0 to 7.0.
A potting mix that includes peat moss, perlite, and compost is recommended to maintain moisture while ensuring good drainage.
Humidity
This plant enjoys high humidity levels, ideally around 50-70%.
To increase humidity, mist the leaves regularly or place a humidifier nearby. Signs of low humidity stress include browning leaf edges and leaf drop.
Temperature
Houttuynia cordata thrives in temperatures between 60-75°F (15-24°C) and is hardy in USDA zones 5-9.
It can tolerate light frost but should be protected from extreme cold and heat, as prolonged exposure can damage the plant.
Fertilizing
Use a balanced liquid fertilizer with an NPK ratio of 10-10-10 every 4-6 weeks during the growing season.
In fall and winter, reduce fertilization to once every 2-3 months. Signs of nutrient deficiency include stunted growth and pale leaves.
Pruning
Prune Houttuynia cordata in early spring to remove any dead or damaged growth and to shape the plant.
Use clean, sharp scissors or pruning shears. Deadheading spent flowers can encourage more blooms and maintain a tidy appearance.
Repotting
Repot Houttuynia cordata every 1-2 years or when you notice roots growing out of the drainage holes.
Choose a pot that is 1-2 inches larger in diameter. Signs it needs repotting include stunted growth and water not absorbing well. To repot, gently remove the plant from its pot, loosen the roots, and place it in fresh soil.
Propagation
Propagation can be done through division or stem cuttings.
For division, carefully dig up the plant in spring or fall, separating the root clumps and replanting them. For stem cuttings, take 4-6 inch cuttings in spring, remove lower leaves, and place them in water or moist soil until roots develop, usually within 2-4 weeks.
When it's unhappy
Yellow leaves
Why it happens
This can be caused by over-watering or nutrient deficiency.
How to fix it

In spring, prune back any dead growth and start fertilizing every 4-6 weeks to promote new growth. Ensure consistent watering as temperatures rise.
Summer
During summer, monitor for pests and maintain adequate moisture. Water more frequently if the weather is particularly hot.
Fall
In fall, reduce watering frequency as the plant enters dormancy. Continue to fertilize until late fall, then stop for the winter.
Winter
In winter, protect the plant from frost and reduce watering to every 2-3 weeks. Avoid fertilizing until spring.
