In warmer climates (zoes 8-10), calla lilies grow well in partial shade (4-6 hours) to full sun (6-8 hours). In cooler climates (zones 3-7), they enjoy full sun.

Keep your Calla Lily consistently moist but not in soggy soil. Use filtered, bottled, or tap water that is sitting 24 hours to release the chemicals and water enough to discharge out of the drainage holes. Once the water is fully drained, replace it into the cache or decorative pot.

The Calla Lily enjoys and thrives in average humidity.

Comfortable room temperatures  will help the Calla Lily to thrive.

Outside: Place in bright, indirect light if grown in a greenhouse and flowering so the leaves don't burn. Inside: Set in bright, indirect light.

Rhizomes planted in containers: Apply a liquid fertilizer especially formulated for flowering bulbs at half strength every two weeks in a container. Rhizomes planted in the garden: Add an organic fertilizer such as bone meal rich in phosphorus, calcium, and a trace of nitrogen. These nutrients will help the roots establish.
A soluble bulb fertilizer like 3-5-3 can also be apart of the soil amendments to give your bulbs a good start.  As the foliage emerges, repeat the bulb fertilizer application each month until they start blooming. Stop when the Calla's start flowering to help extend the life of the bloom.

Cut the leaves back after the first frost when the foliage turns yellow. If you are in a cooler zone (3-7), remove the rhizomes from the soil with an inch of stem attached. Knock off all the soil and lay them on newspaper in a dry place for a week. Do not wet or wash the rhizomes. Sprinkle them with powdered sulfur to protect against fungi while they're in dormancy. Lay on a single layer screen or in a mesh bag so air can circulate around them. Store the rhizomes at 50°F-60°F.

When all chance of frost has passed in the spring, plant in the garden at a depth of 3 to 4 inches deep and 12 to 18 inches apart after the last frost in your planting zone. Place your rhizomes in a horizontal position, so the eyes are facing upward. Add compost or soil conditioners and mix in with the native soil.. Depending on the warmth of the soil, it usually takes 60 days to bloom.

If growing in a planter container, use a well-draining potting soil with perlite to aerate the soil. Add amendments to clay soils in the garden to aerate the soil and allow for good drainage.

Cut the leaves back after the first frost when the foliage turns yellow. Trim back faded flowers to the base of the stem.

Divide the rhizomes in the spring after the last frost in your planting zone. Plant each rhizome (type of root system) in a deep container at least 3-4 inches deep with soil underneath it for rooting. Set the growing tips facing upward. Cover with well-draining soil (add amendments to heavy soil in the garden). Wait until the plant is producing new green leaves before starting to fertilize. Stop fertilizing when buds form.

This plant enjoys bright to medium indirect light.

Keep the soil slightly moist and water when the soil reaches a #5 on the moisture meter. Use filtered, bottled, or tap water sitting 24 hours to release the chemicals and water enough to discharge out of the drainage holes. Once the water is fully drained, replace it into the cache or decorative pot. Don't let the roots sit in standing water. During winter months, water less frequently but keep it humid around the plant.

Add up to 60% humidity by adding a pebble tray filled with water, grouping with other plants or using a humidifier.

Guard your Prayer Plant against temperatures below 60°F to avoid foliage damage.

Outside: Grow in morning light, partial shade (4-6 hours) where nights are above 45°F. Indoors: The Prayer Plant prefers bright to medium, indirect light for at least six hours in a southern, eastern and western windows.

Fertilize monthly during its growing period. Use a high nitrogen liquid fertilizer at half strength to increase foliage health. Reduce during the fall and winter months while the plant is in its dormant phase. Flush the soil periodically to eliminate salts from fertilizing.

When receiving the plant, do not repot immediately but wait at least 6-12 months. Repot in the spring, using a 2" wider pot. (Too large of a pot could cause the soil to dry slower, which is not helpful.) Use a well-draining indoor potting mix with perlite to help with drainage or an african violet potting mix. Place a piece of screening at the bottom of the container over the drainage hole to secure the soil and allow it to drain. Add soil to the bottom to elevate the root ball. Lift the plant and release the roots against the existing planter. Use a clean knife or garden trowel to wedge between the pot and the soil to loosen. Inspect the root ball. Notice if there are any dead or rotting roots and trim off with sterile pruners. If the plant is rootbound, cut through the roots to alleviate continued encircling. Ensure the plant is sitting about 1" below the edge of the pot to avoid water spillage. Add more soil and backfill around the sides by tamping down. Fill up to the soil line but not over. Water thoroughly, leaving the soil damp but not soggy. If settling occurs, add more soil. Enclose the new plantings in plastic bags, mist and keep them in medium light. Remove the plastic bag when the roots are established. You may observe some leaf changes as it acclimates to its new environment. It may suffer some transplant shock depending on how tight the roots were intertwined together. Trim off any declining leaves as it regains its energy and gets rooted into the soil over time.

Trim off any dead or damaged stems to keep energy moving to the healthy leaves. Shower the leaves using a watering can with filtered or rainwater to remove dust. Remove any debris on the soil and replenish soil if needed.

Indoors: Propagate and divide Prayer Plants in the early spring when emerging from dormancy. Pull from the container and brush or wash away the soil carefully. Carefully divide and repot in a rich, indoor potting soil mix or African violet mix. Use a container that has drainage and is deep enough for the roots to grow. Set it in medium to bright, indirect sunlight while they are rooting. Enclose the new plantings in clear plastic bags, mist and keep them in medium light. Remove the plastic bag when the roots are established. You may observe some leaf changes as it acclimates to its new environment. It may suffer some transplant shock depending on how tight the roots were intertwined together. Trim off any declining leaves as it regains its energy and gets rooted into the soil over time. Check the moisture and humidity each day and add misting to keep the soil moist while the roots establish. After 6-8 weeks, roots will begin to establish. You can tug onto the stem to ensure the roots are anchoring well. You can remove the clear plastic bag at this time but still maintain high humidity around the plant. Outdoors: Carefully loosen the soil and dig the roots up and separate the plant in new locations in your garden. Add rich, damp, and loamy soil in a part-shade morning sun location. Water with filtered or rain water at soil level.
