For storage, temperatures and moisture conditions vary for each bulb species. For some flower bulbs, the precise storage conditions are known, while for others the precise conditions are unknown. Whenever the climate is tender enough for the particular bulbs, it is advisable to keep the bulbs in the garden and cover them well before the winter starts. In many cases the plant will bloom better the next year, e.g. Agapanthus, amaryllis belladonna, crinum, canna and lily. In addition, when grown in containers, it is usually best to keep the bulbs in the pot and place it under proper growing/storage conditions in the home or in storage.
