Fall is the time to lift tender tubers and bulbs before any risk of frost can kill them. Because they are cold-sensitive, calacdium tubers will perish in the cold. As a result, they must be taken indoors in northern latitudes, and even in milder areas, they normally die back in the winter. This is great because the tubers, which are the source of the foliage, need time to regenerate. Caladiums are popular indoor plants among gardeners. To maintain the health of the plants and safeguard the tubers, specific procedures must be followed when caring for caladiums inside.
Plants in areas with cold winters may be placed in pots to make transferring them indoors when the weather turns chilly easier. Caladiums are difficult to grow indoors because they demand high humidity, and heated home interiors are typically fairly dry.
In addition, Caladium plants only produce leaves from spring to fall, after which they need to rest for around five months in order to recover and grow again the following spring. By moving containers indoors, you can slightly prolong the foliar display, but eventually the leaves will wither and the tuber will become dormant until mild temperatures arrive.
However, bringing plants indoors in containers will protect the tubers and stop them from being harmed by winter weather.
Can caladiums be grown indoors?
This native to the tropics has heart-shaped leaves that are paper thin and exquisitely adorned, rivaling even the most showy flowering plants.
Magnificent leaves in profusion cover tall, thin stalks. They grow to be around 12 in. (30 cm) length, and they are large. From white with green veins and borders to blushes of rose pink to spotted and marbled red, pink, green, and white leaves, leaf patterns and colors can be very diverse.
Caladium is a South American native that makes a magnificent tropical addition for your home because it thrives indoors in indirect light. The flashy season is likely to continue six months or longer.
Caladiums prefer warm, humid environments. Give them humidity as well as direct, bright light.
Can you grow caladiums indoors or outdoors?
Caladiums are tropical plants with a wide range of hues and patterns. They are indigenous to the South American Amazon River banks. Caladiums look great in landscaping mass plantings, hanging baskets, and pots. The primary colors of caladium are red, pink, and white, and each variety has a special and fascinating color combination made up of two or more of the aforementioned hues.
Where to plant caladiums
Caladiums flourish outdoors in the warmer months and provide your garden or yard a rich, exotic feel. The majority of caladiums prefer shade or partial shade, however certain kinds can also be grown in places with little to no shade (see the caladium catalog page). They are an excellent method to brighten shady regions. They are frequently used in beds, near houses, and as border plants. They make beautiful patio container plants and can also be utilized in window boxes.
When to Plant Caladium Bulbs
Since caladiums are tropical tubers, they NEED warmth to thrive. It is crucial to wait until the soil temperature is at or above 70 degrees Fahrenheit before planting your caladiums. Germination will be greatly delayed by cool weather. On the map on the left, you can see the suggested planting time for your region.
How to Plant Caladium Bulbs
Caladiums are relatively simple to plant. With the eyes up, plant the bulb’s top 1 1/2 to 2 inches below the surface. Peat moss can be added to sandy soil to help it retain moisture. Wrap the planting in mulch and maintain moisture all season long. Use a delayed release fertilizer or a 6-6-6 type fertilizer every six weeks to fertilize. Per bulb, use about a teaspoon.
Storing Caladium Bulbs
Reduce watering, dig up bulbs, and let them air dry for a week when the fall foliage starts to die down. Store at 55 degrees or higher in a dry place. Storage is only relevant for zones 8 and higher. It is not required to dig up caladiums in the deep south during the winter.
Caladiums Indoors
Caladiums make a striking display indoors, and any home will benefit from their warm tones. When summertime comes, you can put them outside because they do well in containers. When cut, caladiums last for two to three weeks and look stunning in a vase or floral arrangement.

How are potted caladiums cared for?
Indirect light that is bright to medium-bright will help your caladium grow the healthiest. It can withstand early morning sunlight, such as that in an eastern or northern window. Stay away from places where it will be in the direct afternoon sun.
When the top 25 percent of the soil is dry, water your caladium. To avoid root rot, moisten the saucer completely and make sure to drain any extra water. Water the plant very sparingly over the winter months when it falls dormant to give it time to recover. in the spring, resuming watering “awaken the plant from its slumber.
Your caladium prefers an environment that is humid. To increase humidity, mist the leaves frequently, put a humidifier nearby, or use a pebble tray.
The ideal temperature range for your caladium is 65–80°F. Steer clear of chilly drafts and abrupt temperature swings. Keep the plant in a place that stays above 60 degrees Fahrenheit during the winter when it is naturally dormant. Warm temperatures of at least 75F in the springtime are beneficial to “Your caladium will awaken more quickly.
Use a liquid houseplant fertilizer once a month during the spring and summer, diluted to half the recommended concentration for optimal results. In order to properly feed your plant, never add fertilizer to dry soil. Instead, wait until the soil is humid. Fall and winter don’t require any fertilizer.
If consumed, your caladium is said to be harmful to both people and animals. can irritate the stomach and mouth.
Your caladium will likely enter a latent stage after growing new leaves, even indoors. This tuberous plant’s typical lifespan looks like this. When the plant’s older leaves begin to fall off in the fall, reduce watering. In the spring, water the caladium, give it a light fertilizer, and maintain it in a warm place to help it emerge from dormancy. As soon as you notice any old, discolored leaves, trim them off.
Where should I put my indoor caladium?
Caladium plants should be kept inside in a room with medium lighting and shade from the midday sun, which will scorch the foliage. Typically, the best exposure is in a window that faces north or east. Caladium houseplant maintenance requires humidity because the tubers are indigenous to tropical jungles in South America and only grow seasonal leaves during the wet, warm season.
The secret to successfully bringing the plant to the inside of the home is to mimic its natural surroundings. Misting and setting a saucer with water and pebbles under the container are two ways to maintain high humidity levels in a warm home. The evaporation will moisten the surrounding air and supply your Caladium with the humidity it needs. Away from heating vents that blow dry air and drafty windows or doors, keep your plant.
You must give your plant plenty of water and attention while it is still in its foliar splendor. Only fertilize a plant when it is actively growing, which is from early spring to late summer. There is no need for special nourishment in the fall and winter. When the soil feels dry to the touch, water it.
Maintain the plant in a room with a minimum temperature of 65 degrees Fahrenheit (18 C.). Allow the leaves to continue to grow until they are completely spent, at which point you should clip them off. The tubers can then be lifted, dried, and stored in peat in a breathable bag, or you can leave them in the ground and stop watering.
Either plant the saved tubers outside in the spring or start watering the potted tubers. Moving the container to a little brighter light will help protect the new shoots from the hot light. Once all of the seeds have fully sprouted, gradually reintroduce the container to the outside until fall, at which point you should start the procedure over.
Does caladium require large pots?
- Start with a sizable planter with drainage holes in the bottom that is at least 18 inches broad and deep.
- Add a layer of tiny rocks that is one inch thick.
- Add a layer of mulch made of pine bark or another filler that drains well, about an inch or two.
- Fill the container with potting mix to within two inches of the rim.
- Remove the caladium plant’s nursery pot with care. Shake the roots free, and if they are too long, cut them. Create a well in the planter’s middle that is a few inches deep, then nestle the caladiums within.
- Include more blooms, like petunias and begonias. Add potting soil, then water the plants in.
Caladiums want four hours or less of filtered sun every day. When choosing kinds, be cautious to check the plant tag since some will tolerate more sun.
A benefit of container gardening is that you may move the pot around until it receives the ideal amount of light.
Where do caladiums thrive in nature?
The large, heart-shaped leaves of caladiums are renowned for their stunning displays of the colors white, pink, red, and green. These are tropical plants that do well in warm, muggy conditions. Caladiums rarely bloom, but their stunning foliage ensures a vibrant display wherever they are planted, including in perennial borders, amid shrubs, under trees, and in containers.
Start with a Better Bulb
Comparing two caladium plants side by side makes it simple to detect differences in quality. Size is used to classify caladium tubers. The largest ones are classified #1 and range in diameter from 1.5 to 2.5. Grade #2 or #3 tubers are smaller ones. Only grade #1 caladium tubers are available from Longfield Gardens. These bigger tubers (as seen on the left) have more “eyes,” or growth points, and develop into bigger, more robust plants.
Plan for Success
Caladiums are great plants for shaded gardens and yards, but the majority of cultivars are surprisingly sun-tolerant. Sun tolerance varies from variation to variety and is influenced by the sun’s intensity as well as how much moisture the plants get.
Caladiums are tropical plants, so unless you grow them in zones 9 to 11, they won’t survive the winter outside. The tubers may be left in the ground all year round in these warm areas. Caladiums are typically cultivated as annuals in zones 3 to 8, and are planted outside in late spring when the soil is warm. Uncertain of your hardness zone? Here is a link to our zone map.
When to Plant: To start growing, caladiums require warm soil and warm overnight temperatures. The tubers won’t grow and might even decay if they are placed in chilly soil. Till the nights are warm and the soil temperature reaches at least 65°F, wait to put the tubers outside. Caladiums can benefit from a head start in milder climes by being sprouted indoors four to six weeks before to planting. Shallowly plant the tubers in seedling flats or pots. To promote sprouting, keep them warm (70F) and barely damp.
How to Plant Caladiums
Caladium tubers should be planted 6″ apart on centers in the northern and central regions. You’ll look lovely and plump as a result of this. They can be planted farther apart in southern regions. You might want to space your plants out more when using pots.
You can plant caladium tubers one at a time or you can prepare a wider space and plant several tubers at once.
Plant tubers about 3″ deep, smooth side down. After planting, the tuber should be covered by 1-2″ of dirt.
Where to Plant Caladiums
Decks, patios, and containers: Add lovely greenery to your outdoor seating places. Caladiums thrive in pots and planters and are the ideal way to liven up a covered deck or shady porch.
Window Boxes: Strap leaf caladiums thrive in hanging planters and window boxes. Use them all summer long to cover your house in vibrant flora.
Entryways and Borders: To soften a path leading to your front door, edge a shaded garden bed, or create a path among shrubs and trees that provide shade, use beautiful leaf caladiums.
Mailbox Gardens: Surrounding your mailbox with lovely plants will improve the curb appeal of your home and turn it into a charming “mini-garden” that everyone may enjoy.
Caladiums can be either cool and understated or brilliant and flamboyant, depending on the variety you choose for your companion plants in the garden. The red-leaved types may compete with hot-colored begonias, coleus, and impatiens, while the pinks, greens, and white flowers look stunning with various delicate hues.
Planting Tips
Wait two to three weeks after the last date of frost before planting your caladiums outdoors. The soil should be between 65 and 70 degrees Fahrenheit throughout the evenings. This will happen in cool climates in early to mid-June.
While most caladium species welcome some shade during the hottest part of the day, certain cultivars are more sun-tolerant than others.
Like the majority of plants, caladiums thrive in rich, well-drained soil. By adding compost or top soil, you can enhance the texture, fertility, and ability of your soil to retain moisture. Caladiums require constant hydration throughout the growing season and benefit from a little bit of liquid fertilizer every now and then.
Usually, large tubers have several eyes (growth points). One dominant eye may be present in small tubers. You can plant two tiny tubers together for a bushier appearance. When planting tubers, seasoned caladium growers occasionally “de-eye” them. It can be challenging to learn this method. To promote the growth of other sprouts, the dominant eye is removed.
Caring for Your Caladium After the Growing Season
Since caladiums are tropical plants, their tubers cannot endure harsh winters. It’s typically better to treat your caladiums as annuals and plant new bulbs each spring if you live in USDA zones 3–7. At the end of the growing season, there is no need to dig the tubers because they will fall apart throughout the winter.
Caladiums are not consistently hardy in USDA hardiness zone 8, but you can try protecting the tubers from the cold with a thick layer of mulch. A different choice is to keep them inside over the winter. Dig up the tubers if you wish to, but don’t wait until the soil temperature dips below 55°F. To make it simpler to identify the different varieties, leave some leaf clinging.
Spread the plants out after digging in a location that is shielded from rain, cold, and harsh sunshine. Cut the foliage from the tubers, keeping like varieties together, after allowing them to dry for at least a week. Pack the tubers loosely in dry peat moss or put them in mesh bags. Keep cold and dark, where the temperature won’t drop below 60 degrees Fahrenheit. In the spring, replant.
In zones 8 through 12, caladium tubers are hardy and do not require any additional care to survive the winter. The leaves will begin to droop and finally wither when the plants go into dormancy in late summer or early fall. Let the tubers remain in the ground and watch for the plants to reappear in the spring. The tubers will put on another fantastic performance for you the following year, provided the soil is well-drained and does not freeze.
