LIGHTA Caladium requires very bright indirect light. Keep your plant out of the direct sun to prevent leaf burn. WATER The soil of a Caladium houseplant should be moist but never soggy during the growing season. As the leaves of the Caladium start to die in the early fall and the plant goes into its resting/dormant period, gradually reduce the watering until the soil has thoroughly dried out. FERTILIZER Fertilize your Caladium every two weeks when it is actively growing with a water-soluble plant food high in nitrogen at 1/2 the recommended strength. TEMPERATUREA Caladium Plant likes warm temperatures between 70-85 degrees with as little fluctuation in temperature as possible. During the five or so months when a Caladium is dormant, the temperature should be cooler but never below 55 degrees. HUMIDITY Your Caladium Plants need a great deal of humidity. There are several ways to increase the humidity in a dry home or office: Set Caladiums on a bed of wet gravel or pebbles. Be sure the plant is sitting on the pebbles and not in the water. Place a small humidifier in the room with your Caladiums. Group several houseplants near each other to create a mini greenhouse effect. FLOWERING Caladium flowers are inconspicuous. The leaves are the beautiful part of this plant. PESTS The colorful leaves of Caladium houseplants attract Mealy Bugs, spider mites, and Aphids. Gently wash any pests off the leaves with warm soapy water. DISEASES The high humidity that Caladium Plants require may cause fungal diseases such as Fusarium and Pythium and bacterial diseases such as Leaf Spot Disease. Providing good air circulation and keeping Caladium leaves dry, helps prevent these problems.SOILCaladium houseplants really like a slightly acidic fast-draining soil. Once a month water your Caladium with leftover tea or a very dilute solution of water and vinegar.POT SIZEPlant Caladium 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 tubers is the best propagation method RESTING PERIOD In the fall, when the Caladium leaves die, move your plant to a dry, dark, cool location. Water sparingly every six weeks. A Caladium must "rest" and be dormant for about 5 months each year before it starts to grow again.
