Troubleshooting
Willow Gentian problems — and how to fix them
Willow Gentian (Gentiana asclepiadea) 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.
Self-seeding invasiveness
In conditions it likes — moist, shaded, humus-rich soil — G. asclepiadea seeds around freely and can spread vigorously. Deadhead before seed sets if spread is unwanted, or allow it to naturalise in a woodland garden where it will fill gaps beautifully.
Leaf scorch in sun or dry conditions
Pale, scorched patches appear on foliage when plants are sited in full sun or if soil dries out during summer. Move to a shadier position or mulch heavily and water consistently. The plant rarely dies outright from this but looks unsightly and weakens over time.
Slow establishment after transplanting
Like most gentians, G. asclepiadea resents root disturbance and may sulk for a season after moving or dividing. Plant young specimens from pots into their permanent position; if division is necessary, do it carefully in early spring before growth begins.
