Calla Lily

A Beginner's Guide to Cally Lily Plant Care | All you Need to Grow!

Family: Araceae
Common Name: Calla Lily
Botanical Name: Zantedeschia aethiopica

A single plant can easily define elegance and grace. The Calla Lily embodies sophistication with its timeless vase-shaped flowers, elongated leaves, and slender silhouette. These indoor plants form from bulbs (rhizomes) and will bloom for 6-8 weeks indoors, but once the flowers and foliage have finished displaying their wonder, you can cut the leaves back to the soil line and place them in a cool dark setting. Re-pot the bulbs in a few months and begin to water again once spring has arrived, and your Calla Lily will start to grow again! Learn more about how to care for your Calla Lily!

Light

Calla Lilies demand full sun or very intense indirect light when grown indoors, and without over 6-8 hours of intense bright light, they start to decline. Still, if you are using them as display pieces for the holidays, or any event, they can last for weeks on end when placed in less-than-ideal lighting!

Water

Although Calla Lilies emerge from bulbs, they require that their roots never dry out completely. Be prepared to soak the soil every time you water them, and drain any excess water from the grow pot or cover pot that you display them in. Water them less during the winter months when they are not actively growing. Suppose your indoor temperatures are above 70°F and your Calla Lilies consistently receive over 8 hours of indirect sunlight. In that case, you will need to check the soil for watering more often than if kept in cooler and shadier environments.

Soil

You may need to transplant your Calla Lily every year or so, depending on how fast it grows. We recommend using a soil mixture that is 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, and they can keep the soil wet for long periods, which can cause root damage. Be adventurous and learn how to create your own universal potting soil mixture!

Temperature

Calla Lilies love warm temperatures, but they will grow perfectly fine in average household temperatures between 65-75°F. Keep them away from cold windows and frequently used doors in the wintertime to extend their blooming period. They are cold sensitive and prolonged exposure to icy air will cause serious damage to the foliage and flowers!

Humidity

Extra dampness in the air will help keep your Calla Lily quenched and healthy, but it is not essential if you are using them to decorate a table setting or for your holiday decor. If you intend to keep them as houseplants, consider increasing the humidity around them to keep their 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 Calla Lily some extra moisture and is a good solution during the winter or if you live in a dry climate. Learn how to increase the humidity for your houseplants!

Fertilizer

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!

Growth Rate

Zantedeschia is a fast-growing indoor plant that can grow to 24" in height when given proper care during the growing season! The flowers (spathes) can reach up to 3 in height. They rarely grow taller than 36", but they can spread out horizontally if re-potted into a larger container.

Pet Friend or Foe

Calla Lilies are toxic to pets! Foe.

Pro Tips

  1. Re-pot your calla lilies every year to provide them with the nutrients they need to give you a spectacular flowering display!
  2. The best time to re-pot your Zantedeschia is in the early spring.
  3. When your Calla Lily becomes too wide for the pot, remove the plant, divide the rhizomes and plant the divisions to create more plants.
  4. Be careful to never let the soil dry out while your Calla Lily is blooming! They need consistently moist soil. (Do be careful to not over water the soil as this can be fatal to the plant.)
