Calla lilies prefer bright, indirect light. They can tolerate some direct sunlight, but excessive exposure to the sun can scorch their leaves. Place them in a location that receives morning sunlight or partial shade during the day.

Calla lilies prefer moderate temperatures between 60°F and 75°F (15°C and 24°C). They can tolerate slightly cooler temperatures but are sensitive to frost. Protect them from freezing temperatures and keep them away from drafts or cold air.

Calla lilies require regular watering to keep the soil evenly moist but not waterlogged. Water them when the top inch (2.5 cm) of soil feels dry. Ensure that the pot or container has good drainage to prevent standing water, which can lead to root rot.

Calla lilies appreciate moderate to high humidity levels. If the air in your home is dry, increase humidity by placing a tray filled with water and pebbles near the plant. Ensure that the bottom of the pot is above the water level to prevent waterlogging. You can also mist the leaves occasionally.

Use a well-draining potting mix that retains some moisture. A mixture of peat moss, perlite, and garden soil or a commercial potting mix for flowering plants is suitable. Good drainage is important to prevent waterlogged roots.

Feed your Calla lilies with a balanced, water-soluble fertilizer during the growing season (spring and summer). Follow the package instructions for the appropriate dilution ratio and frequency. Reduce or stop fertilization during the dormant period in winter.

Plant Calla lilies in pots or containers that have drainage holes to prevent waterlogging. Choose a pot that allows enough room for the plant to grow. When repotting, handle the rhizomes (bulb-like structures) carefully, as they are delicate.

Remove any spent flowers or yellowing leaves by cutting them off at the base. This promotes the growth of new flowers and maintains the plant's appearance. After the blooming period, you can trim back the entire plant to encourage new growth.
