5. Water regularly the first few weeks as the roots develop. If you live in cold areas, where freezing can be prolonged and severe, either store your containers in a shed or garage where they will be protected from freezing solid, or wrap containers (group them) with bubble wrap and cover with branches. The bulbs should be cold, but not too cold! Ideally temperatures colder than 48° F most of the time, but not so cold that the bulbs freeze. If storing outdoors, store in the shade to avoid the drastic temperature changes that can happen on a sunny day. Alternatively, plant your pots in the ground for winter storage, allowing the earth to regulate the temperature. Wherever you store them, protect the pots from hungry mice by covering them with mesh or another pot. Keep your bulbs moderately moist, but not soggy through winter. Experimenting with different locations will help you find the place that works just right for your bulbs.
6. Once the danger of severe frost is past, bring out or uncover your containers, and continue watering. Depending upon your location you may want to transition gradually. Most bulbs need a full sun location to do their best, so place your containers to maximize spring sun.
7. Once the foliage yellows after flowering, just empty the bulbs from the pots, let them dry completely and store them in a cool, dry place until it’s time to replant them again. Plant them in the garden this time and start with fresh bulbs in your pots.
