Can I Plant A Potted Calla Lily Outside? (Solved)

As we mentioned in the previous post How Long Do Potted Calla Lilies Last?, let’s come to this article to answer the question “Can I plant a potted calla lily outside?” Here is a little information about Calla Lilies.

Calla lily is a common name for several members of the family Araceae. They can be found in the tropical wetlands of South Africa and Malawi. This indicates that it is a water-loving plant that thrives in warm areas.

The calla lily can grow in temperate areas, despite its native habitat of wetlands and humid temperatures such as the tropics. The blossoms might be white, yellow, pink, red, or orange in color. They thrive in part-shade conditions. They can be grown outside all year in warm climates.

If you plant the flowers outside, they will blossom profusely. You can pick some flowers to put in vases to adorn the house on important occasions. Callas are rhizomatous plants with big green or arc-shaped leaves that can grow to be several feet tall. 

Even if the weather is hot in the summer, flowers can bloom all day provided they are properly planted and cared for, along with a consistent watering schedule.

Can I plant a potted calla lily outside?

Calla lilies are, to some extent, outdoor plants. They will flower in direct sunlight, but their leaves should be maintained inside or in partial shade. Many gardeners consider these plants to be annuals, planting them outside in the spring and bringing them inside before the first frost. 

Calla lilies aren’t particularly hardy in the winter. Because they grow in USDA plant hardiness zones 6 to 10 – just north of the South’s warmest sections – you should treat your calla lilies as annuals and replace them every year if you live anywhere where it freezes.

Calla lilies are cold resilient and can be planted outside all year, but you can maintain them as houseplants for several years before they get too big. Their leaves become yellow and fade back over time, making the plants appear lanky. 

If you live in a frost-free environment, though, you may leave your calla outside all year if you give it enough light. Make cautious to adapt your calla lily to its new habitat before planting it outside. If a calla is kept outside all year, it will likely grow quicker and flower more frequently.

However, if you decide to transfer it outside in the spring after it has spent the winter indoors, gradually expose the potted plant to outdoor circumstances over the course of a week or so.

How to grow Calla Lilies in your garden?

Calla Lilies come in a variety of colors, such as purple, yellow, and black, and are recognized by the color of the bloom. Furthermore, they have a wide range of species.

1. What is the best way to breed Calla Lilies?

After the plants have blossomed, we continue to care for them for the next three months, wait for the leaves to dry, then dig up the tubers, clean the soil, and bring them in to propagate gorgeous Calla Lilies in the garden. Check to see whether the tubers exhibit indications of rot or mold before storing them in a cold, dry location; if they do, remove them.

To help the plants blossom more beautifully and uniformly, we need to chop off the old old stem before planting and split each big and tiny tuber to plant in separate beds.

2. Soil treatment before planting Calla Lilies

Calla lilies should be planted in soil that contains a lot of humus, has a high nutrient content, is moist, and has adequate drainage. Before planting the bulbs, we should treat the soil a month ahead of time to loosen it up. a porous and permeable surface

We can use different types of decaying manure to enrich the soil and assist the tubers growing to have the ability to absorb water by making planting beds that are higher and wider, with each bed about 20 inches apart. absorb more nutrients to help plants grow taller.

Because the plants will have room to expand later, calla lily bulbs should be put 12 inches apart in the trench, then backfilled about 2 inches. This approach can be used to germinate plants.

3. Water the plants

We should be waterless and only enough to keep the soil moist at this point in the planting process. Add more water to the plants after they have taken root and sprouted. To prevent tuber rot, water plants three times per week.

Reduce the frequency of watering to once a week once the plant has begun to grow its main leaves and develop.

4. Fertilize plants

When the plant has 3-4 main leaves, we can use diluted fertilizer to water the plant. You can water it in the evening, to help the plant cool and absorb more evenly.

When the trunk is strong, we weed and scrape the soil around the base of the tree, which helps to increase the amount of NPK fertilizer for the tree, helping the plant to grow more.

5. Diseases that may affect Calla Lily

White dots on the leaves and brown spots on the petals are caused by fungal diseases that affect calla lilies. It’s possible that your plant is drought-stressed if its leaves are yellowing or falling off without any signs of illness. 

To aid recovery, give your calla lily additional water. Powdery mildew affects calla lilies on occasion, but if caught early enough, it can be avoided.

Tips for you to grow Calla Lilies outdoor

Purchase calla lily bulbs in the late fall or early winter to develop calla lily plants. Keep them cool and inactive until spring in a cellar, garage, or other cool location.

Plant them at the same depth they were previously growing in rich, well-draining soil. Plant them so that the dirt just covers the spot where the bulb bulges out. Mulch the soil around the plant’s base to keep it moist.

Your calla lilies will blossom outside in the spring. Cut down new growth to approximately 6 inches above ground level as you observe it sprouting. This will compel your plant to focus all of its energy on root development and the formation of a huge bulb that is ready to bloom.

During the growing season, keep your calla lilies well-watered and fertilize them once or twice a month with a balanced blooming fertilizer for bulbs and tubers.

Outside, calla lilies require at least six hours of direct sunlight per day, as well as a well-drained, well-balanced soil medium. Choose a location with fertile, moist soil that isn’t too wet. Calla lilies require a lot of water, however, they should not be allowed to sit in it or have their feet in it.

Calla lilies are usually planted after the danger of frost has gone, because they are sensitive to cold weather. Before the weather gets too hot, the optimum time to grow calla lilies is between March and early May.
