Caladium

The Caladium gives you a decorative choice in air purifying plants. Its large colorful leaves naturally absorb toxins and release oxygen into the atmosphere, making this tropical perennial a healthy addition to your indoor space. While Caladium care may be fairly easy if growing it outdoors, it requires a bit more love and attention as an indoor plant.

How to care for your Caladium

Use these instructions to care for a Caladium. This guide will tell you how to water a Caladium; its light, temperature, humidity preferences and any additional care it might need to help it grow.

Caladium

LIGHT

Caladiums flourish in indirect light. Full sun exposure scorches the leaves, so keeping the plant close to a window but away from the intense noon and afternoon sunlight works best. 

WATER

Your Caladium thrives in moist soil, but be careful not to overwater since this causes root rotting. To find out if your plant is thirsty, check to see if 25% of the soil’s surface is dry. If so, you can water the Caladium while ensuring proper drainage and emptying out any excess liquid. During the winter, you’ll water your plant sparingly or not at all until the leaves start sprouting again in the spring.

HUMIDITY

Caladium care also requires a moist atmosphere. Ideally, the Caladium grows best when the humidity level reaches 60-75%. So if needed, you can place a small humidifier close by or use a pebble tray filled with water. Grouping your Caladium with other moisture-loving plants also helps. Plus, you can mist the leaves on a regular basis. Just be careful that the soil doesn’t become water-logged. 

TEMPERATURE

Keeping a warm environment between 60℉-80℉ is vital to your Caladium’s health. Hence, you’ll need to place your plant away from drafty windows and doors and air vents. Also, try to avoid sudden changes in room temperature.

FOOD

Monthly feedings during the spring and summer provide optimal nutrition for your plant. As part of your Caladium care regimen, dilute a liquid fertilizer at half the strength. Before feeding your plant, check the soil’s dryness because you should never apply the fertilizer on a dry surface. During the fall and winter, you stop fertilizing the plant.

TOXICITY

The Caladium is toxic for humans and pets. Ingesting causes mouth and stomach irritation.

ADDITIONAL CARE

Even indoors, your caladium will most likely go into a dormant stage after producing new leaves. This is the normal lifecycle of this tuberous plant. Cut back on watering when old leaves start to die back in the fall, and to encourage the plant to come out of dormancy in the spring, you’ll want to water, apply a weak fertilizer, and keep the caladium in a warm location. Prune off the old discoloring leaves as they appear.

What's a Caladium?

Botanical Classification: Caladium spp.

About

Caladiums are a large genus of tropical perennial plants with over 1000 vibrant cultivars. Traditionally used in outdoor gardening in warmer climates, these broadleaf plants can bring a dramatic or subtle splash of color to any indoor space. While these plants require a little extra care when grown indoors, their lush showy growth makes it well worth the effort.

Most caladiums are native to the warm tropical rainforests of Central and South America. When grown indoors, they need ample bright, but indirect sunlight to grow. If grown outdoors they prefer shade to dappled sunlight. Too much light will cause the vibrant colors to fade. During their growing season, these plants like their rich well-draining soil to be kept evenly moist but never soggy. Provide this plant with ample humidity and keep away from cold drafts, as they do not tolerate colder temperatures.

Fun Fact

While these plants rarely flower, especially indoors, they can produce a spadix surrounded by a yellow-green spathe. You can prune off these flowers to help the plant focus on leaf growth.
