Hyacinths are hardy and need almost no winter protection outdoors. If the plants are overwintered indoors, you must ensure that they have a rest period. In addition, the tubers must be stored very cold for a while.
How do I overwinter hyacinths correctly?
Hyacinths are hardy and do not require winter protection outdoors. They overwinter in a pot in a cool, dry place in an unheated place. As a tuber, store it in a very cool place for a few weeks, for example in the vegetable compartment of the refrigerator.
Overwintering hyacinths outdoors
Since hyacinths can tolerate frost, you do not need to cover the bulbs in the bed to protect them from the cold.
Overwintering hyacinths in pots
During the winter break, keep the hyacinth bulb in the pot cool and dry. An unheated hallway window is well suited. To keep the tuber cold, take it outside for several days in cold weather.
Overwintering hyacinths as tubers
In order for the tuber to sprout next year, it needs a cold phase. Place them in a very cool place for a few weeks. Alternatively, the vegetable compartment of the refrigerator will also work.
Tips & Tricks
Store hyacinth tubers dark, dry and as cool as possible. The onions overwinter best in a little dry peat or wood shavings.
