Calla lilies (Zantedeschia) are planted from rhizomes which are also called bulbs. They work well grown either indoors or outdoors and are frequently used in bridal bouquets. Calla lilies flower from late spring throughout early summer and come in a variety of different colors, the most common of which are red, pink, white, purple and yellow. They are easy to grow and require very little upkeep.

Difficulty:
Moderately Easy

Instructions

    1. Plant calla lily bulbs in the spring after the last frost has come and gone. Choose an area that receives either full sun or partial shade and has loose soil with good drainage.
    2. Plant the bulb (rhizome) in the ground at a depth of 4 inches. The calla lily bulb should be placed in a horizontal direction with the growing side pointed upward.
    3. Space additional calla lily bulbs 12 inches apart from each other. Water all bulbs thoroughly immediately after planting and keep the soil moist at all times during the growing season. Calla lilies go dormant after the growing season has passed and do not require frequent watering during this time.
    4. Fertilize calla lilies once a month during the growing season. Keep a layer of mulch around to aid in keeping the soil moist and weed-free.
    5. Dig up the bulbs after the first frost of the season, usually in the fall. Shake off excess soil and let them dry out for two days.
    6. Store bulbs in peat moss in an area that is cool, dark and dry for the remainder of the fall and winter season.

Tips & Warnings

  • If you prefer not to store the bulbs, you can start them indoors as houseplants and then transplant them outside when warmer temperatures return.

  • Calla lilies cannot withstand temperatures that drop below 25 degrees F and they will die if left outside in these conditions.
