Give Lots of Light
Being native to tropical climatic conditions, calla lily plants require ample amounts of light for optimal growth and timely blooming. Make sure that you keep the potted plant in a bright windowsill, where it receives natural light throughout the day. During cold winter months, you can keep it outdoors for some time during the day for getting adequate sunlight.
The Temperature Factor
Next to light factor, regulating indoor temperature is a prerequisite for growing healthy calla lily in pots and containers. The preferable temperature for indoor gardening of this tropical flowering plant is 70°F. Extreme fluctuation in light and temperature can take a toll on potted calla lilies. So, make sure you protect it from the scorching sun and indoor heaters.
Soil Should be Moist
Watering potted calla lilies should be such that the potting mixture is moist, but not soggy. For achieving this, you will need to irrigate it on a regular basis. At the same time, avoid excess watering to minimize plant problems. A simple, yet effective approach to retain soil moisture is providing a layer of mulch. By doing so, the need for repeated watering will be reduced.
Fertilizing is a Must
This tropical plant needs fertile soil and sufficient nutrients to grow luxuriantly. Taking this into consideration, feed it with an all-purpose fertilizer (10-10-10) once in every 3-4 weeks. It is best to refer to the manufacturer's instructions for deciding correct dosage and application steps. Stop fertilizing your calla lily plant, once it starts developing flower buds.
Care for Calla Lily Blooms
Within 3 months of planting calla lily in a container, it will produce blooms. Then, you are expected to water and feed your plant in the same way as before, even after the blooming period is over. This is to ensure development of healthy tubers and restore nutrients for next year's vegetative growth and flowering.
Calla Lily Problems and Diseases
Though calla lily leaves look attractive with their dark color and leathery surface, they are grown for blooms. It does happen that potted calla lily has healthy foliage, but it fails to flower. This may be due to poor tuber quality, insufficient light and excessive watering of the plant.

Remove diseased parts in the early stages to avoid severe infestation.
