Hyacinthus orientalis 'Jan Bos' problems — and how to fix them
Hyacinthus orientalis 'Jan Bos' (Hyacinthus orientalis 'Jan Bos') 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 in cold, waterlogged ground. Plant in sharp drainage and keep dry through summer dormancy.
Floppy spikes
Warmth or poor light causes weak, leaning stems. Grow cool and bright; expect looser, more natural spikes after the first year.
Skin irritation from bulbs
Oxalate crystals on the bulbs irritate skin. Wear gloves when planting or handling stored bulbs.
Smaller spikes after forcing
Forced bulbs flower less fully the following year. Plant out, feed, and let foliage die back to recover the bulb.
