Troubleshooting
Squinancywort problems — and how to fix them
Squinancywort (Asperula cynanchica) is generally low-drama, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Root rot on heavy soils
Plants fail quickly in clay or waterlogged ground; always grow in sharply drained, gritty, alkaline soil or a raised chalk-bed to replicate natural habitat.
Poor establishment on acidic soil
Will not thrive at low pH; if soil is neutral or acidic, amend with horticultural lime or crushed chalk before planting.
