Caladium plants should be grown in a medium-light environment with protection from the midday sun, which can scorch the foliage. The best exposure is usually from a northern or eastern window. Caladium tubers are native to South American tropical forests and grow seasonal foliage during the rainy, warm season, therefore humidity is essential for Caladium houseplant care.
The key to successfully introducing the plant to the home interior is to mimic the plant’s native environment. Misting and placing a saucer filled with stones and water under the container might help keep the humidity high in a warm home. The evaporation will moisten the surrounding air and supply the humidity that your Caladium requires. Keep your plant away from drafty windows or doors, as well as heating vents that blast dry air.
You’ll need to maintain your plant watered and happy while it’s still in its foliar splendor. Fertilize the plant only when it is actively growing, which is from spring to late summer. No extra meal is required in the fall and winter. When the soil feels dry to the touch, water it.
Maintain a temperature of at least 65 degrees Fahrenheit for the plant (18 C.). Allow the leaves to die back until they are completely wasted before cutting them off. After that, you can either take the tubers, dry them, and store them in peat in a breathable bag, or leave them in the soil and stop watering them.
In the spring, either plant the tubers that have been stored or start watering the tubers that have been potted. Move the container to a slightly stronger light, being cautious not to burn the new shoots. Once the container has blossomed completely, slowly reintroduce it to the outdoors until fall, then repeat the process.
How do you take care of potted caladiums?
Ensure that the soil is kept evenly moist during the growing season. Allowing the soil to dry out will cause the leaves to yellow and drop. To assist your plants retain moisture, apply a layer of mulch around them.
Fertilizing:
Caladiums don’t require much fertilizer, and too much can cause the leaves to burn. Proven Winners horticulturists recommend applying a controlled-release fertilizer at 1/4 strength of what you would use for blooming plants. It’s also possible to utilize liquid fertilizer.
Overwintering:
Tubers will fall dormant and the foliage will die back in warmer regions (Zone 9 or higher). Leave the tubers in the ground and cut the leaves to the ground. If you want to replant them the following spring in a colder environment (Zone 8 or below), you must dig them up in the fall before frost. Allow the soil to dry out when the leaves have fallen naturally in the fall, then dig up the tubers and store them in a dry spot no cooler than 65° F.
Propagation:
After bringing tubers out of winter storage in the spring, divide them. Each tuber should be cut into smaller pieces with at least one “eye” or knob from which new growth will emerge. Allow a day for the cut pieces to dry before planting.
How often should I water a caladium?
Moisture and feeding are the most critical aspects of caladium care. Fertilizer will help the plants grow stronger so that they can produce enough tubers for the following growing season.
Caladiums require constant watering, especially during periods of drought. Watering them on a weekly basis is actually suggested. Container-grown caladiums should be examined every day and watered as needed. Mulch around caladium plants, especially in pots, will aid to conserve and maintain moisture.
Caladiums must be dug up in the fall and preserved indoors throughout the winter in cold locations because they are considered sensitive perennials. Caladiums can be carefully plucked from the ground once their foliage turns yellow and begins to fall apart. Place the plants in a warm, dry place for at least two weeks to allow them to dry out. After that, remove the foliage and place the tubers in a netted bag or box with dry peat moss on top. Put the tubers away in a cold, dry place. You may transplant outside once spring arrives. Caladiums can be overwintered inside if they are grown in containers.
You may add these lovely plants to your landscape now that you know how to plant caladiums. Caladium bulb planting is simple, and with good caladium maintenance, they can last for years.
Do caladiums like sun or shade?
Caladiums thrive in shaded areas of the yard and garden. They thrive in full to partial shade in southern climates. Most caladiums can be grown in the sun in northern climates if they are given enough water and their leaves are shaded during the warmest portion of the day.
Is caladium a good indoor plant?
They thrive in high heat, strong but indirect light, and plenty of humidity when cultivated inside. Caladium foliage lasts only a few months even in ideal conditions before the leaves fall back and the plant stays dormant, which is typical.
How do you keep caladiums alive?
Caladiums prefer bright, indirect light to thrive (full sun would fry them in a heartbeat). Keep the soil evenly moist don’t allow it get too dry, but don’t let it get too wet, or the tubers will rot. Group pots together, even with other houseplants, to enhance humidity.
What do I feed caladiums?
Caladiums thrive in the shady understory of open, high-branched trees. In full shade, they will do pretty well, but the color may not be as vibrant. Caladiums have traditionally required shelter from direct sunlight for optimal development and color, but some of the newer cultivars may tolerate a few hours of direct sunlight every day. When cultivated in the sun, most pink-leaved caladiums turn brownish and burned.
Caladiums prefer damp, warm soil. It is preferable to have a minimum soil temperature of 70°F. Cool soil temperatures cause tubers to decay before sprouting if they are planted too early in the spring. Some gardeners choose to start tubers inside in a shallow flat or flower pot with damp peat moss or potting soil. Cover the tubers with just enough soil and place the container in a warm, well-lit area. Tubers should be started indoors four weeks before being planted outside.
Caladiums should be planted in well-drained soil with a pH of 6.0 to 6.5 for optimal growth. To improve soil aeration, drainage, and organic matter content, add a 2- to 3-inch layer of pine bark mulch or compost to the soil. Unless the soil is thoroughly aerated, root and leaf growth will be limited. Add a complete fertilizer, such as 8-8-8, at a rate of 1 to 2 pound per 100 square feet of bed area (2 tablespoons per square foot). Small tubers should be planted 2 inches deep and 8 inches apart, while giant tubers should be planted 12 inches apart. From the top of the tuber, both roots and shoots emerge; place the knobby side up.
To conserve moisture and keep the soil cool, mulch with a 2- to 3-inch layer of organic material. Leaves with more green color and less of the highly sought, vivid colors may result from soil temperatures above 85°F. Nitrogen fertilization at high amounts can have the same effect. Caladiums are heavy feeders of potash and phosphate, and they require enough of moisture and fertilizer throughout the summer to produce healthy tubers for the following growing season. During the growing season, use 1 tablespoon of 5-10-10 fertilizer per square foot every 4 to 6 weeks. Use a heaping tablespoonful for individual plants; a level teaspoon per pot for plants grown in containers. Allow no fertilizer to come into contact with the leaves. To avoid fertilizer burn, water properly after fertilizing. Caladiums are drought-resistant and need to be watered frequently.
Plants will occasionally produce a bloom that resembles that of a Jack-in-the-Pulpit or a calla lily. The flower pulls energy away from the leaves and reduces tuber size, thus most home gardeners choose to remove it.
Are caladiums hard to care for?
Tender tubers and bulbs must be lifted in the fall to avoid being killed by frost. Caladium tubers are frost fragile, and if exposed to cold, they will perish. As a result, they must be taken indoors in northern latitudes, and even in milder climates, they will normally die back in the winter. This is all well and good, but the tubers that produce the foliage require some rest. Caladiums are popular indoor plants among gardeners. Caladium care indoors requires some additional guidelines to keep the plants healthy and the tubers safe.
Plants that grow in areas with cold winters could be grown in containers to make it easier to bring them inside when the weather turns chilly. Caladiums are difficult to grow as indoor plants because they require high humidity, which is difficult to provide in warm home interiors.
Caladium plants also only produce leaves from spring to fall, and then require a five-month rest time to recharge and sprout again in spring. You can prolong the foliar display by putting containers indoors, but the leaves will eventually die back and the tuber will become dormant until the weather warms again.
Bringing plants indoors in containers will maintain the tubers and protect them from damage during the winter months when they are exposed to the elements.
Do caladiums like rain?
Wet soil is more likely to harm tubers than cold. Tubers may rot if the bed is not well-drained and is damp during the winter. Caladiums need a lot of water when they’re growing, but they like to be dry when they’re dormant. This can be an issue if the location where the caladiums are growing stays damp for long periods of time during rainy winter weather, therefore it’s better to dig and store them.
Do caladiums like water?
Caladium is a heat-loving, moisture-loving greenhouse plant. Watering should be done on a regular basis, but in a moderate amount. Spray water on the leaves all year, but especially during the summer, to reproduce the moisture levels of its native habitat. Maintain a slight moisture level in the soil mix and ensure that water drains adequately.
Can caladiums be in full sun?
Caladiums that are sun tolerant can be planted in full sun, however additional watering may be required. Sun-loving caladiums include Red Ruffles, a dwarf caladium, and Gingerland, a lance leaf caladium. Caladiums prefer the shade or filtered sunlight.
