Growing Calla Lilies Outdoors


Although it is one of the easiest plants to grow, the Calla Lilies are sensitive to inclement weather and need special conditions to thrive. Depending on the zone you live in, you may want to consider these 10 basic tips on how to care for Calla Lilies:


  • Plant them in loose soil in the spring
  • Do not allow the soil dry out
  • Callas can thrive in soggy soil if given plenty of sunshine
  • Ensure plenty of sunshine or partly-shady areas in hot climates
  • Fertilize weekly during the growing season with high potassium fertilizers
  • Plant deeply and sparsely (4-5 inches apart)
  • Use mulch or bark to keep the soil moist, never use gravel
  • Cease watering for 2-3 months during dormant period
  • Let the plant die back in the winter, it will flourish in the spring
  • Store tubers during the winter in dry, frost-free areas such as a shed or a garage
  • It is important to remember that Calla Lilies are poisonous and should not be planted in areas easily accessible to children or pets. They should also be strategically placed where the temperature does not exceed 85 degrees as they will be exposed to heat stress. In the late fall, they should be lifted out of the soil when the temperature falls below 25 degrees and stored over the winter months.



The plant can become invasive as its profuse diffusion can lead to excessive growth in your garden. Pruning the flowers again will stop excessive multiplication and hold the plant within its pre-planned borders. It will also prevent any fungal formation and wilting of the plants. Fungus attacks often occur inside the indoor environments and can become a nuisance.
