Cultivation Instructions

Indoor Planting: They are frost tender so cannot be grown outdoors until all danger of frost has passed. Start growth indoors in February to April in a rich soil with plenty of grit to aid drainage. Plant the rhizomes 5cms below the soil surface and keep soils moist but not wet until they are growing. Once established in a pot they can be left for a few years as long as they are protected from frost over winter. If you are growing caladiums indoors keep them in a well ventilated room that remains warm and has plenty of light but not direct sun light.

Outdoor Planting:  Caladium like to be grown in a rich soil in the shade. Soil temperature is an important consideration, as planting too early outdoors can cause tubers to rot. Plant from April on wards outside, these plants thrive in moist, well-drained soil and are generally happier in partial shade. When you plant caladiums, you should plant them 5-8cms deep and 20-25cms apart. Plant Caladium tubers with the eye buds, facing up. This may sometimes be difficult to distinguish in some varieties but those that are planted upside down will still perform.

Feed with bone meal or similar during the growing period to ensure they remain health for years to come. Plant in areas that are not exposed to the worst of the elements and in soils that have not been freshly manured. Regularly feed during the growing season with foods such as well rotted manures, Tomato feed and bone meal.

Care tips:

Growing caladiums is easy with proper caladium care. These tropical-like plants are commonly grown for their multi-colored foliage, which may be green, white, red, or pink. Caladiums can be grown in containers or clumped together within beds and borders

Keep well fed during the growing season and if possible mulch borders with well rotted manure or compost over the winter. Not hardy so in cold gardens they may need to be overwintered indoors.
