Hibernate hyacinths outdoors
Since hyacinths can tolerate frost, you do not need to cover the onions in the bed to protect them from the cold.
Hibernate hyacinths in a pot
During the winter break, put the hyacinth bulbs in the pot in a cool and dry place. An unheated hallway window is well suited. To keep the tuber cold, take it outside for several days in cold weather.
Hibernate hyacinths as a tuber
In order for the tuber to sprout next year, it needs a cold phase. Put them out in a very cool place for a few weeks. The vegetable compartment of the refrigerator can also do the trick.
Tips & Tricks
Store hyacinth bulbs in a dark, dry and cool place as possible. The onions overwinter best in a little dry peat or wood wool.
