The rhizomes take about weeks to start flowering depending upon the cultivar and planting date. When Calla Lilies are planted in the spring, they will produce flowers between midsummer and early fall for weeks. Their flowering period depends on the temperature, amount of light and the variety. In climates where Calla Lilies are perennial, they typically bloom in late spring to early summer. Aftercare Provide consistent moisture during the growing season and do not allow the soil to dry out.
Feed with a balanced liquid fertiliser every two weeks until the flowers have faded. Mulch annually in fall with well rotted garden compost or manure. Remove the flower stems after the blooms have faded.
Zantedeschia makes excellent cut flowers and have one of the longest vase life among cut flowers up to 2 weeks. The flowers which are fully open with their stamens visible can be harvested. This should be done in the cool of the morning or evening. The flowers should be pulled rather than cut. Cutting dammages both flowers and tubers. Propagate by division, in spring.
Small rhizomes that have been overwintered in pots under cover can be cut up into sections, each with a visible bud. Large overwintered clumps in the garden can be divided by lifting the plant before there is much top growth, and chopping through the roots with a spade and dividing into smaller sections. Overwintering Most calla lilies are winter hardy in zones , so in these warm climates the rhizomes can be left right in the ground. If you live in a colder area and you want to save your rhizomes for next spring, you may dig them up before the first frost and store them over winter before replanting them next spring.
As soon as temperatures drop below freezing and the foliage turns brown, cut down the foliage and stems to about in. If you are growing different varieties of calla lilies, you should label them.

Zones: Although Z. In containers they look best planted just 4" apart. Once the plants have a few leaves, you can begin watering more generously. After planting, it may take 2 weeks or more for the first calla shoots to appear. Once that happens, the plants grow quickly. In warm climates, where calla lilies are perennial, the plants typically flower in early summer.
When calla lilies are planted in the spring, flowering is usually delayed until late summer. During the growing season, calla lilies appreciate a monthly dose of liquid fertilizer. This is especially important when they are grown in containers. In warm climates where calla lilies are winter hardy zones , the rhizomes can be left in the ground to bloom again the following summer. The plants may need to be divided every few years to keep them blooming well. In cooler areas zones , calla lilies are usually treated as annuals, with new bulbs planted each spring.
This is important to calla lily care in winter because it allows the outer skin of the rhizome to toughen up or cure. After the calla lily rhizomes have dried, place them in a paper bag or wrap them separately in newspaper. Store them in a cool, dry place, somewhere that stays around 50 F; usually, a garage or basement works well. You may have to contend with several issues when growing calla lilies, most notably bacterial soft rot, which affects the rhizomes, and botrytis , which is a fungal disease that causes a filmy grey mold to grow over the plant's petals, stems, and leaves.
To reduce the risk of fungal diseases, don't overwater the plants, and make sure to plant your calla lilies far enough apart so that they have ample air circulation.
Various pests can also be an issue for calla lilies, including insects like aphids, slugs, and spider mites. Treat the plants with a mild insecticidal soap or horticultural oil like neem oil to combat these issues.

When this plant fails to bloom, it's usually because it has too much nitrogen, doesn't get enough water, or lacks light. To promote blooms, switch your fertilizer to one that has a higher ratio of phosphorus. Provide ample water, and make sure your calla lilies have full sun or at least 6 hours of sunlight. After blooming has finished for the season, leave the foliage in place.
It should only be removed when the foliage turns yellow. Continue to fertilize and water the plant until that point. The plant will rebloom again after a period of dormancy, usually for two months, during the winter season.
It's generally easy to grow calla lilies. Other than regular water, they do not need much care. However, if their growing needs aren't met, they can suffer. If you notice a brown edge on the leaves, it may be a sign that your fertilizer has too much nitrogen in it. If your plant grows rapidly and looks lush but has brown-edged leaves, a nitrogen-rich fertilizer can cause that.
Your plant will likely not bloom either. Calla lilies are water lovers. If they are not getting enough water, they may not bloom, will look stunted, and leaves will appear yellowed and wilted. Water calla lilies consistently to keep your plant's foliage healthy and encourage flowering; stunted growth can also be caused by lack of sunlight.
Plant droop can be caused by too little and too much watering. Overwatering typically leads to fungal infections like root rot, soft rot, or anthracnose leaf blight. Also, too much nitrogen in fertilizer can lead to drooping stems and flowers. If it doesn't have enough water, adding water will help it perk up. You can help your plant recover from fungal infections by uprooting the plant, removing any mushy, blackened root, apply a fungicide, and repot it in a sterilized pot with a fresh, well-draining potting mix.
