Although by nature an outdoor plant, the calla lily thrives in an interior environment. Paying attention to a few very fundamental growing conditions will keep this rhizome content indoors.
Southern Africa is the natural habitat of the Zantedeschia aethiopica. Since these conditions are substantially different from those found naturally in other regions of the world, this plant is accustomed to them.
Do calla lilies thrive more indoors or outdoors?
First of all, calla lilies frequently grow on the margins of streams or ponds because they like to thrive as marginal aquatic plants. For those who frequently water their lawns, this is a nice perk! Never let your indoor calla lilies dry out by keeping them consistently moist. Even so, make sure it doesn’t sit in standing water for an extended period of time. You can even keep some water in the saucer it sits in.
Regularly fertilizing your plants with a low nitrogen fertilizer can help them flower throughout the growing season.
While calla lilies grown inside prefer some sunlight, harsh noon sun should be avoided since it might burn the foliage. For this plant, an eastern window with morning sun or a western window with afternoon sun is best.
The best growing range for calla lilies indoors is between 65 and 75 degrees Fahrenheit (18 and 24 degrees Celsius). Except when your plant turns dormant, avoid keeping a growing plant in temperatures below 55 degrees Fahrenheit (13 degrees Celsius).
Your calla lily might benefit from spending the warm seasons outside. When transferring your plants from indoors to the outside, be sure to harden them off to prevent the foliage from burning. When the weather is right to bring your plant outside and gradually add more sun, let it sit in complete shade for at least a week.
If you are in a region with intense sun, moderate shade is advised. As long as you meet the plant’s moisture requirements, you can safely use partial or even full sun in other regions.
Can I grow a calla lily in a pot outside?
- Plant in full sun or moderate shade (some shade is necessary in the South and warm inland areas of the West unless the soil is continually wet) and rich moist soil once the threat of frost has passed.
- The growth points of rhizomes should be planted pointing up and horizontally.
- Container gardening (3 out of 12 “garden or in a pot. Only three rhizomes should be planted in containers “deep.
- Hardy to Zone 9 (20F), although plants in Zone 8 (10F) and even Zone 7 can survive the winter with a thick layer of mulch put in the fall (0).
- When frost approaches in the fall in colder climates, dig the rhizomes and keep them indoors in dry peat moss or sand between 60 and 75 degrees Fahrenheit.
- It is possible to keep calla lilies that have been grown in containers over the winter. Bring the container inside in the fall and fully stop providing water until you wish to restart development in the spring.
How long do calla lilies in pots last?
Beautiful tubular blossoms on calla lily bushes are very gorgeous when they are in full bloom. They can seem to fade too rapidly, too, when purchased already potted from a big-box retailer. Ever wonder how long calla lilies in pots are supposed to last?
Calla lilies in pots can stay in an active stage of growth for around four months. This encompasses the first six weeks of foliage growth and the subsequent six to eight weeks of blooming. Following blooming, the plant’s foliage will start to yellow and fade until it goes dormant. After some dormancy, the Calla Lily rhizome will bloom once more.
Elegant Calla Lilies are also very simple to grow. Since they can usually be grown year-round, we can cultivate them both indoors and outdoors depending on the season.
I always make an effort to maintain a plant growing indoors, especially in the winter to bring some light inside. Inside, calla lilies are the ideal plant to grow. They are a minimal maintenance plant that doesn’t require a lot of sun or general care.
How are calla lilies maintained indoors?
If you recently received a calla lily in a pot as a present, they make lovely houseplants.
Here are some pointers for maintaining callas indoors:
- Keep the ground wet but not drenched.
- Luminous, indirect lighting
- while in flower, monthly liquid fertilizer application
- Avoid the vents for the air conditioning and heating.
- When the plant goes dormant, water less (November)
- Once the leaves have died, trim them off at the soil line.
- During dormancy, let callas rest in a cool, dark location.
- annual repotting before the growing season
Where should calla lilies be planted for optimum results?
Calla lilies are simple to grow and give perennial gardens, cutting gardens, and container plantings a refined appearance. The unusual blossoms are available in a variety of stunning hues, including as traditional white (a favorite for weddings), yellow, orange, pink, rose, lavender, and deep maroon.
The foliage of the plants is sleek and sword-like and frequently has white freckles. All through the season, both before and after the blooms bloom, calla lily foliage is tidy and appealing. Fresh calla lilies are always attractive, whether they are in a vase or a garden.
Start with a Better Plant
Comparing two calla lily rhizomes side by side makes it simple to spot changes in quality. Rhizomes that have just been harvested are ranked by circumference. A huge, 14–16 cm rhizome (shown at far left) will develop into a larger plant with a more striking flower display.
Plan for Success
Calla lilies do well in either full sun or moderate shade in warm areas. In cooler climates, they thrive in direct sunlight.
In zones 8 to 10, calla lilies can withstand the winter. They can either be cultivated as annuals in colder climates or dug out in the fall and brought indoors to be replanted in the spring. See the USDA Hardiness zone map for more information.
When to Plant: After all threat of frost has gone, calla lilies should be planted in the spring. It is advisable to wait until the soil has warmed to at least 65F in chilly areas. The rhizomes can be planted in indoor pots approximately a month before being planted outdoors to give them a head start.
Where to Plant Calla Lilies
In flowerbeds and borders, calla lilies can reach heights of one to two feet, depending on the cultivar. They are therefore a fantastic choice for the center or front of a flowerbed. The season-long aesthetic of the spotted foliage.
Cut flower gardens: Calla lilies make excellent bouquets. They are simple to arrange and can stay fresh in a vase for up to two weeks. You may cultivate a broad variety of different hues and have plenty of flowers for bouquets by planting callas in a cutting garden.
Containers: Calla lilies thrive in planters and containers. Although they can be combined with other annuals, they typically thrive on their own in a pot. Weeks pass before the blossoms fade.
Planting Tips for Calla Lilies
Calla lilies should be planted in well-drained soil, just like most other plants. Use a high-quality growing mix as opposed to garden soil if you’re growing them in containers.
It’s crucial to use minimal water when planting the rhizomes. Watering can be increased after the plants develop a few leaves.
What to Expect
The first calla shoots may not emerge for up to two weeks after planting. The plants then grow swiftly after that.
Calla lilies are perennial perennials that bloom in warm areas in the early summer. Calla lilies typically don’t bloom until the end of the summer if they are planted in the spring.
Calla lilies benefit from a monthly dosage of liquid fertilizer during the growing season. Particularly when they are cultivated in containers, this is crucial.
Caring for Calla Lilies After They Bloom
The rhizomes of calla lilies can be left in the ground to bloom once more the following summer in warm locations where they are winter hardy (zones 8–10). To keep the plants blooming well, the plants might need to be divided every few years.
Calla lilies are often managed as annuals in milder climates (zones 3-7), with fresh bulbs being sown each spring. Even if the bulbs are dug out and overwintered indoors, the results might not be the same the following year.
Here’s what to do if you want to try storing your calla lilies for the next year. Throughout the entire growth season, fertilize the plants. As soon as the blossoms start to fade, cut the flower stalks off. Keeping the plants from going to seed can help save energy for the flowers the following year. Feed the plants regularly until the foliage starts to turn yellow.
Dig up the rhizomes and clip off the foliage, keeping an inch or two of stem attached, once the leaves have fallen back or after the first frost. The rhizomes should be placed in a box with just damp peat moss to cure for a few days in a warm, dry area. Keep the box at 50–60°F in a dark, dry location. Make sure the rhizomes are not too dry or too damp during the winter by checking them once or twice (shriveling). In the spring, replant.
What is the lifespan of calla lilies?
What is the lifespan of calla lilies? The addition of calla lilies to a bouquet or other floral design is always a good idea. Calla lily blossoms can endure up to two weeks after being cut.
How should a calla lily be cared for outside?
- Calla lilies may thrive in either full or partial sunlight. In cold summer climates, full sun is ideal; in hot climates, partial shade is desirable.
- Calla lilies thrive on soils that are rich in organic matter, wet, and well-drained. Consistent moisture is necessary, but to stop rot, don’t overwater.
- Select a protected area.
- In hardiness zones 8 through 10, calla lilies are winter-hardy. The tubers are typically handled as annuals in cooler regions (zones 3-7) and planted in the spring after the risk of frost has passed. However, you can dig up your bulbs before the first frost and preserve them over the winter before planting them again in the spring if you want to save them for that season. Uncertain of your growing zone? Look here.
- For beds and borders, cutting gardens, pots, planters, and containers, calla lilies are excellent choices. They make excellent houseplants and can even be cultivated indoors.
- Calla lilies are among the cut flower varieties with the longest vase lifetimes, making them superb cut flowers (up to 2 weeks). They look stunning in fresh floral arrangements and bridal bouquets. If you want to pluck a flower to put in a vase, keep in mind that cutting it with a knife will harm both the flower and the rhizome. As an alternative, carefully remove the bloom stalk from the plant. Harvesting should be done in the cool of the morning or evening when the flowers are fully open and the stamens are visible.
How are exterior calla lilies cared for in pots?
Rhizomes from calla lilies grow best when they are planted one inch (2.5 cm) deep and one to two (2.5–5 cm) apart. Calla lilies require well-draining pots that are at least 10 to 12 inches (25–31 cm) in diameter. Despite the fact that calla lilies require continually moist soil, poor drainage can result in rots and fungus infections. The planting medium should be able to hold onto moisture without becoming overly damp.
Typically, calla plants planted in containers are watered when the top inch or two (2.5–5 cm) of the soil feels dry to the touch. After that, water them completely and deeply. Overwatering may be indicated by brown foliage tips. Every three to four weeks in the spring and summer, calla lilies in pots will also benefit from a general-purpose 10-10-10 or 5-10-10 fertilizer. Stop fertilizing as soon as the blossoming is finished.
In full sun to partial shade, calla lilies thrive. Calla lilies should ideally be grown in containers where they can get around six hours of direct sunlight each day. The recommended temperature range for calla lilies grown in containers is 60 to 75 degrees Fahrenheit (15 to 23 degrees Celsius) during the day and no lower than 55 degrees Fahrenheit at night (12 C.). These optimal temperatures should be maintained if potted calla lilies are brought indoors and nurtured as houseplants during the winter.
Are calla lilies recurrent each year?
Calla lilies sent as gifts are frequently treated as annuals. They discard a potted flower after its flowers have faded whether they received it or purchased it for spring décor. However, calla lilies are actually perennials, so you may keep your potted plant and watch it bloom again the following year.
Do calla lilies bloom again? How you care for your plant and where you store it during the winter will determine how it does.
Watering in Spring
Calla lilies require frequent watering during the spring because of their brilliant green leaves and colorful blossoms. They should be watered every 4-5 days during the growing season.
Watering in Summer
The calla lilies require extra water because it is so hot outside and water evaporates quickly in the summer. Water them every other day, keep an eye on how moist the potting soil is occasionally, and make sure the water doesn’t stand still.
Watering in Autumn
You still need to water more frequently in the early autumn, perhaps once every three days. You can limit watering as needed as the temperature drops to prevent water from wrongly evaporating in the soil from the low temperature.
Watering in Winter
Pay close attention to calla lily water management in the winter, understand the dry-wet concept, water once every 10 days, and wipe the foliage with a rag once a week to not only eliminate dust but also to make the leaves of calla lilies greener.
Watering during the growing season
When the plant is at its best in the spring and fall, it should be watered once daily to maintain the soil moist, and when the weather is dry, it is necessary to constantly mist the plant to raise the air humidity.
Watering during dormancy
When the temperature is between 25°C (77°F) and 5°C (41°F), the calla lily enters a period of dormancy when its water needs are relatively low. During this time, watering must be strictly regulated, and you must always check the soil’s dryness before watering. Generally, watering should occur every 7–10 days for the best results.
Caution
However, the location, temperature, and climate all affect how frequently to water the calla lily. Water it less if it is kept inside.
Spray the area around the calla lily when the weather is extremely dry to raise the air’s humidity and promote greater growth. On days when it’s raining, stop watering and quickly empty the pot of water.
