Troubleshooting
Hyacinthus orientalis 'Delft Blue' problems — and how to fix them
Hyacinthus orientalis 'Delft Blue' (Hyacinthus orientalis 'Delft Blue') 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 in wet soil
The fleshy bulb rots quickly in cold, waterlogged ground. Plant in sharply drained soil or gritty compost and avoid summer watering once dormant.
Floppy or loose spikes
Warmth, low light or ageing bulbs cause weak, leaning stems. Grow cool and bright; expect looser, more natural spikes in years two and three.
Skin irritation from handling
Bulbs carry calcium oxalate crystals that irritate skin. Wear gloves when planting or handling stored bulbs.
Failure to re-flower well
Spikes shrink after the first forced year. Plant out in the garden after flowering, feed, and let foliage die back to recover the bulb.
