Troubleshooting
Houttuynia cordata problems — and how to fix them
Houttuynia cordata (Houttuynia cordata) is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Invasive spread
Running rhizomes colonise borders and ponds rapidly and are extremely hard to eradicate. Always grow in a sunken bottomless pot or contained bed, and never plant where roots can reach a watercourse.
Leaf scorch and wilting
Caused by the soil drying out, especially in full sun. Keep the root zone permanently wet; reposition pots into a water-filled saucer during hot spells.
Poor leaf colour in shade
Plants grown in low light lose their warm tints, become leggy and flower sparsely. Move to a sunnier, still-moist spot to restore compact, colourful growth.
Winter dieback confusion
Top growth collapses entirely in autumn, which can look like death. The rhizomes are hardy and reshoot in late spring; mark the position and keep the soil moist over winter.
