Troubleshooting
Common Hyacinth problems — and how to fix them
Common Hyacinth (Hyacinthus orientalis) 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.
Bulb rot (Pythium / Botrytis)
Overwatering or poorly drained soil encourages fungal rots; symptoms are soft, foul-smelling bulbs and collapsed stems. Improve drainage and avoid planting in the same spot two years running.
Blind bulbs (no flower spike)
Caused by insufficient chilling (fewer than 12 weeks below 9 °C / 48 °F), planting too shallow, or exhausted bulbs replanted without feeding. Ensure adequate cold period and replace exhausted bulbs every 2–3 years.
Aphids and bulb mites
Aphids cluster at the base of flower spikes; bulb mites (Rhizoglyphus spp.) attack stored bulbs, causing sunken, dry lesions. Inspect bulbs at lifting and discard any showing mite damage.
