Growing and Caring for Caladium: Essential Tips

A Caladium, or Elephant Ear plant, a member of the the Araceae family, is a tuberous, rooted perennial that originally came from South America. It is closely related to an Alocasia, whose common name is also Elephant Ear plant. All plants in the Araceae family, including the diffenbachia and philodendron, contain calcium oxalate crystals and are extremely poisonous. Caladium plants, whether indoors or outdoors, look beautiful from late spring until early fall and then die back and become dorɱaпt until early spring.

 

Description

Caladiums are bulb plants grown for their large, paper-thin, arrow-shaped, colorful leaves that are often more spectacular than ɱaпy flowers. The most popular indoor varieties are the “fancy-leafed” and “lance-leafed” types. The leaves, some as long as 24 inches, have marbled, spotted, or veined patterns in red, pink, white, and green.

How to care for Caladium?

Light

A caladium plant requires very bright indirect light. Keep a caladium plant out of the direct sun to prevent leaf burn.

Water

The soil of a caladium plant should be moist but never soggy during the growing season. As the leaves start to die in the early fall and the caladium plant goes into its resting/dorɱaпt period, gradually reduce the water to about once every 4-6 weeks.

Fertilizer

Fertilize a caladium plant every two weeks when it is actively growing with a water-soluble plant food, high in nitrogen, diluted to at 1/2 the recommended strength. Always dilute the plant food you are giving a caladium plant or the salt in the fertilizer will burn the leaves.

Temperature

A caladium plant likes warm temperatures between 70°-85°F (21.1°-29.4°C) with as little fluctuation in temperature as possible. During the five or so months when a caladium plant is dorɱaпt, the temperature should be cooler but never below 55°F (12.8°C).

Humidity

The main reason a caladium plant gets brown or curling leaves, is lack of sufficient humidity. There are several ways to increase the humidity around your caladium plant. You can set the plant on a bed of wet gravel or pebbles. Be sure the caladium plant is sitting on the pebbles and not in the water. Place a small humidifier in the room near your caladium plant. Group several houseplants near each other to create a mini greenhouse effect which increases the humidity in the room.

Flowering

The flowers on a caladium plant are inconspicuous. The leaves are the beautiful part of a caladium plant.

Pests

The colorful leaves of a caladium plants attract mealy bugs, spider mites, and aphids. Gently wash off any pests you see on the delicate leaves with warm soapy water. If the problem persists, spray the caladium plant with Neem Oil.

Diseases

The high humidity a caladium plant requires can encourage fungal diseases such as fusarium and pythium and bacterial diseases such as leaf spot. Providing good air circulation and keeping the leaves of a caladium plant dry, helps prevent diseases. Use Neem Oil or a commercial fungicide that can be mixed with the soil to treat these fungal and bacterial diseases.

Soil

A caladium plant likes a slightly acidic, fast-draining soil. Once a month water your caladium plant with leftover tea or a very dilute solution of water and vinegar.

Pot Size

Plant caladium plant tubers in a 4″-6″ pot that has drip holes in the bottom. Cover the tubers with 1″-2″ of soil.

Propagation

Caladiums do best when propagated in the spring after the plant has had a 5-month “rest.” Digging up and dividing the calathea plant tubers, and planting the tubers in a small pot of loose soil, is the best propagation method.

Resting Period

Caladium plants, whether indoors or outdoors, look beautiful from late spring until early fall and then die back and become dorɱaпt until early spring. In the fall, when the caladium plant leaves die, move the plant to a dry, dark, cool location. Water sparingly every six weeks. A caladium plant must “rest” and be dorɱaпt for about 5 months each year before it starts to grow again.

Poisonous Plant Info

A Caladium plant is a very poisonous plant with a #3 toxicity level.

Can I Store My Caladium Plant Bulbs in the Garage During the Winter?

You can store your caladium plant tubers (bulbs) in the garage as long as the temperature stays above 55°F (12.8°C).

I Moved My Caladium Plant Outside for the Summer, Now It Has Big Brown Spots on the Leaves. Were These Spots Caused by an Insect or a Disease?

The brown spots on your caladium plant are probably leaf burn from the sun. These plants love bright light, but never put them in direct sun.
