In any case, you should keep in mind that pots of any kind will be exposed to the winter cold from all sides and the bulbs will therefore have less protection than in the garden soil, for example. It is therefore advisable to additionally protect them from the frost with fleece. The containers should also be protected from rain and winter sun. These tips should help you get the flower bulbs through the winter:

  • Ideally, the box or pot with the bulbs spends the winter in a place with temperatures between 32-46F/0-8C degrees. If this is not possible:
  • Do not leave boxes and pots hanging, but place them on the floor on polystyrene or wood (to isolate and protect them from below).
  • The wall of the house is optimal, because there the planter is also protected from rain.
  • Wrap the containers with suitable fleece. Several layers are necessary.
  • As protection from the sun, spread some brushwood on top of the potting soil, if you do not have a shady location.
