Forcing Hyacinth Bulbs Found Sprouting in Winter

Vicki in Tuscany, Italy found 4 hyacinth bulbs in a terracotta vase with green shoots after months dry. Bulbs sit half-exposed. Nights sub-zero, days 7–9°C. Dry leaves left as cold protection. Asks how to get them to bloom again in spring.

Expert Answer: Bulbs are "forcing" themselves—cold period followed by warmth triggers early bloom. They need 12 weeks cold then warmer temps. Since growing, water and fertilize well; may bloom in February. To delay, keep barely moist in total darkness (black trash bag) for a couple weeks. Forcing guide: Seeds of Knowledge.
