Daylilies grow well outdoors in most of the United States. They are also easily grown indoors in containers during the winter. With adequate sunlight and warmth, as well as sufficient water, daylilies can be kept blooming indoors all year round, even in the coldest of climates.
Choose one of the small-growing varieties of daylillies. Talk with your local nursery expert and choose a cultivar that is adaptable to indoor containers.
Fill a container with a 50/50 mix of potting soil and manure or compost. Daylilies like well-drained soil that is high in organic nutrients. The container should be at least 50 percent larger than the current root ball or the current container to allow for growth.
Dig a hole in the soil in your container that is large enough to accommodate all of the roots of your daylily. Place the plant in the hole and gently press the soil around the plant at the same depth as the plant was originally planted.
Water well, until water begins dripping out of the drain hole in the bottom of the container. Empty the drain pan so the container does not sit in water.
Keep the soil around your daylily moist, but not soggy. Daylilies do not like soggy soil. Lightly mist the foliage of your daylilies with water every day to provide them with some humidity.
Place your daylily in a sunny window where it will get at least five to six hours of sunlight every day. Keep the temperature between 65 and 75 degrees Fahrenheit during the day and do not let nighttime temperatures drop below 60 degrees Fahrenheit.
