Calla lilies grow as perennials from USDA zones 7 through 10 and do well in containers.
Yes, you can plant a potted calla lily outside, by making sure the rhizomes are grown in well-drained potting soil about 6 to 8 weeks before the last spring frost. Plant in a 70-75degF location.
Keep the soil moist, but not wet.
They do best in full sun and should be kept moist but not wet.
Containers are a good option for growing calla lilies
While Calla lilies do best outdoors (in containers or on ground), they are also adaptable to indoor growth and do well in containers.
The most basic growing conditions for calla lilies are very similar to those for plants grown indoors, so it is not difficult to grow these flowers indoors.
First, you need to dig up the calla lily bulb from the ground. Be sure to leave one eye and cut the bulb into pieces.
Dry the bulbs for a day to form a callus.
Once the danger of frost has passed, you can plant the calla lily in a sunny container.
Keep the soil moist, but not soggy. You should water the calla lily once a week to promote good growth.
During wintertime, bring the calla lily indoors. If the weather is particularly cold outside, you can plant the calla lily in a cold frame or greenhouse.
Although many varieties of calla lilies are hardy, it’s still important to protect them from cold and wind.
When planting calla lilies in a pot, choose one with drainage holes. Terracotta pots have open walls that allow air through the walls, which helps prevent overwatering.
Clay pots require more frequent watering. If growing calla lilies outdoors, you can dig up the rhizomes for overwintering if the USDA hardiness zone is cooler than 8. Just remember to brush the dirt off gently before planting, as washing could lead to fungal root rot.
A calla lily is a good choice for container gardening. These plants require little space and will fill gaps in your flowerbeds.
They can be planted between other plants, around fences, or in border gardens. For best results, plant two or three rhizomes per container. Then, water them occasionally. You’ll notice that the callas are very colorful and showy!
Once they have finished blooming, calla lilies can stay in containers for the winter. If your climate falls into a cold zone, you can dig up and mulch them in the fall.
Then, once the weather is warm again, simply replant them outdoors. Containers are a great option for growing calla lilies outside, as they are not hardy in the zone.
Calla Lilies grow as perennials in USDA zones 7 through 10
In most climates, the Potted Calla Lily will survive well in a variety of growing conditions and can last for years in the same location. It is a hardy perennial plant that grows between one and five feet tall.
The blooms of the calla lily are stunning, with their beautiful petals encircling the finger-shaped spadix. Its flowers are beautiful and fragrant, and calla lilies grow best in soil that closely resembles their native habitat.
For those living in Zones 7 through 10, the potted Calla Lily should be planted as a perennial. The bulbs of this flower are best overwintered indoors, but they will not produce as well next year.
Fertilize the potted Calla Lily once a month to maintain their beauty and prevent seed-set. Continue fertilizing your calla lily until the foliage starts to turn yellow.
A plant grown in a pot will need to be kept warm and sheltered in the winter. In colder climates, however, it may not perennialize and will need to be brought inside for the winter. It will require regular watering and bright light. You should use gloves when handling calla lilies because all parts are poisonous.
Their hardiness is generally determined by the climate they grow in. In USDA zones seven through 10, they can grow in temperatures up to ten degrees Fahrenheit. Plants should be planted shallowly in good potting soil and have adequate drainage.
The roots of potted callas should be buried in the garden soil, but some growers prefer to plant them in a pot.
Although calla lilies are hardy in most regions, they do best in areas where they do not get very cold.
To ensure that your Calla Lily does well in your garden, make sure you give it a monthly dose of liquid fertilizer, which is especially important for plants in pots.
They will bloom the following summer and may even need to be divided every few years, so it is important to keep up the fertilization and watering.
Calla Lilies bloom year-round
Calla lilies are hardy houseplants that enjoy partial shade, a bright window, and good ventilation.
The colorful hybrid varieties, however, need drier conditions and higher ground. They also need consistent moisture or the roots could rot.
Aside from being easy to care for, calla lilies are tolerant of a range of soil types, from heavy clay to rocky soil.
If the climate is right, calla lilies will bloom year-round, lasting from three to 10 weeks from their first bloom. In good conditions, calla lilies bloom for as long as 10 days. They will wither early in colder climates but can last until late summer in a warm area.
Because they are perennials, you won’t need to dig up the plants each fall.
To keep calla lilies in good condition, water regularly and maintain a moderate to high level of relative humidity. The recommended level is 65 to 75 percent. If you don’t see any flowers at all, check for soil pH.
You should water callas a few times a week to prevent them from becoming root bound. And remember to change the pot if your plant does not seem to be flowering.
If you plan to keep your calla lilies in a pot, you should monitor the growth of each plant regularly and divide them if they become too crowded.
To ensure a long-lasting bloom, divide your calla lily every few years and store it during the winter. A calla lily plant should bloom again after 60 to 90 days, so be sure to care for it well!
A good idea is to harvest the rhizome from your potted calla lilies when the leaves die off. Remove the rhizome from the pot and store it in a cool place until spring. If temperatures are below freezing, cut back the stems and foliage.
Make sure that you label your rhizome as you do with other plants. If you don’t do that, your calla lily is not likely to grow again.
Calla Lilies are easy to care for
A potted calla lily is a perfect plant to bring indoors during winter months. You can plant them in potting soil with well-drained pH levels or in the ground after the last frost.
Care for a calla lily in a pot is similar to that for its plant-grown counterpart.
During the first two weeks, water them sparingly, but gradually increase watering rates. The plants should be spaced at least 30 cm apart.
If you plan to plant a calla lily in a pot, make sure the pot is at least 6 inches deep. The soil should be a high organic content and good at retaining water.
The soil should have a hole in the bottom to allow water to drain thoroughly. Water calla lilies as needed, but wait until new green leaves appear to avoid overwatering.
A calla lily is a hardy plant that prefers moist, well-drained soil. In colder climates, you must move it indoors during the winter.
If you’d like to enjoy a stunning calla lily year-round, you can grow it in a water garden. It will thrive in a pond or water garden. Just make sure you place it in an area where the soil is not too shallow as it can cause root rot.
Takeaway
A potted calla lily is a versatile plant that is easy to care for and looks great in a vase. The foliage is sword-like and is covered in white freckles.
Despite being an easy plant to care for, calla lilies perform best in a pot and last for several weeks.
A potted calla lily can be kept in a vase or a terrarium for extra beauty.
For best results, water your potted calla lily regularly. Water it thoroughly when the first inch of the soil is dry. Do not overwater.
You can apply a general-purpose fertilizer to your calla lily in a pot. It is best to apply it in the spring and again in the summer.
Water it less often once it has finished blooming. A balanced liquid fertilizer every two to three weeks is recommended.
