Common Pests and Diseases

How to Take Care of Calla Lilies

To ensure the healthy growth of the plant, below are some of the most important things that you have to remember:

  • Watering is important to sustain the growth of the plant and to provide the roots with the nourishment that is essential for its growth. Nonetheless, especially in the case of hybrid calla lilies, be careful to not overwater it. The soil should not be soggy. If water stays for a long period, this can encourage root rot and other diseases. Poke the soil. When it is dry and firm, this is one indication that it needs watering.
  • The plant will also need winter protection. They will most likely not survive the frost. If they are in containers, move them indoors. If they are in a garden bed, on the other hand, you have to dig the bulbs and transfer it in an indoor environment with an ideal temperature. To harvest the bulb, follow the directions in the next section.
  • If you have indoor calla lilies, it is necessary that you keep it out from direct sources of heat. Keep it away from appliances and AC vents, among others. Too much heat, even from the sun, can delay the growth and can also lead to scorching.
  • In most instances, there is no need to fertilize. If it is taking too long for the flower to grow, however, you might need to apply fertilizer. Do this sparingly. Too much fertilizer can only do more harm than good. This can encourage too much foliage growth without blooming.
  • If there are dead flowers or foliage, remove them immediately. The same thing is true if they are showing signs of diseases. Do not wait for the infection to spread to its healthier parts.
  • The plant also needs humidity. If you are living in a place that is too dry or hot, one good thing to do is to mist the flowers so that they will be humid. If you have calla lilies in pots, on the other hand, you can place it at the top of a tray with pebbles and water.

Harvesting Calla Lilies

Start by digging, making sure that you will not damage the roots. Excavate at a diameter of at least six inches away from the plant and at a depth of around eight inches. Use a soil fork to loosen the soil surrounding the roots so that it will be easier for you to pull it out. Lift the root from the soil and gently brush the roots to take off any remaining soil. Cut the top of the foliage if you intend to store the bulb.


To add a pop of color in the garden or even indoors, growing calla lily is a good idea. It does not take too much effort and time. The care requirements are minimal and the success rate is high. With the right location, soil, and watering, you will not have a hard time making sure that the plant grows in its best condition.
