Your Millennium Queen Calla Lily needs full sun or intense indirect light when growing indoors. It will decline if your plant doesn’t get 6-8 hours of intense bright light. 


Millennium Queen Calla Lillie’s roots can never dry out completely. Be prepared to soak the soil every time you water this plant and drain any extra water from the grow pot or cover the pot where you display your plant. Watering should be reduced once the plant enters dormancy. This is usually during the winter months. In the summer, your plant may need to be watered more often. However, do not overwater your plant.  


You might need to transplant it yearly, depending on how fast your Millennium Queen Calla Lily grows. We recommend using a soil mixture rich in organic matter, has good drainage, and is light and loose. Most bagged potting soil will be fine, but avoid potting mixes that contain moisture-retaining crystals, as they can keep the soil wet for long periods. This can lead to root damage. Be adventurous and learn how to create your own universal potting soil mixture!


Millennium Queen Calla Lilies love warm temperatures, but they will grow perfectly fine in average household temperatures between 65-75°F. Please keep it away from cold windows and frequently used doors in winter to extend their blooming period. This plant is cold-sensitive, and prolonged exposure to icy air will cause severe damage to the foliage and flowers! 


Extra dampness in the air will help keep your Millennium Queen Calla Lily quenched and healthy. If you intend to keep it as a houseplant, consider increasing the humidity around it to keep its leaf tips from browning. A naturally humid spot, like a kitchen or bathroom, is a good fit. Using a humidifier or a pebble tray with water can give your Millennium Queen Calla Lily some extra moisture and is a good solution during the winter or in a dry climate. Learn how to increase the humidity of your houseplants!


Millennium Queen Calla Lilies do not require a lot of feeding or fertilizing after they have started to bloom. Water with a ¼-strength diluted complete liquid fertilizer every few weeks, a few months before they are estimated to bloom! Hold off on fertilizing the plant during the fall and winter after it has gone dormant!
