Set the pot in a warm, sunny windowsill once the plant stops blooming. Fertilize once ever two weeks with a balanced, soluble fertilizer at the label recommended rate.
Cut back the foliage to soil level once the leaves yellow and die back on their own, usually six to eight weeks after blooming completes. Stop watering the plant.
Lift the bulbs from the pot once the soil has dried to the touch. Inspect the bulbs for soft spots that signify rot. Discard any damaged bulbs.
Spread the bulbs out in a dry room away from direct sunlight. Allow the bulbs to dry for three to five days.
Place the bulbs in a brown paper bag. Fold the top of the bag over so the bag is closed loosely. Store in a cool, dry place until you are ready to replant in fall.
