Caladiums are a little difficult to care for. To ensure their proper growth, meeting the various light, water, soil, and temperature or humidity requirements is key. 

Caladiums Light Requirement

Caladiums are shade plants that do well when grown under full shade or bright indirect sunlight. Newer varieties or cultivars can grow under full direct sunlight, but prolonged exposure can be bad for the potted plant as it can leave its foliage scorched. 

When grown outdoors, you would want to pick a shaded area, over time, as the plant matures, it should be able to withstand some high degree of sunlight. 

For Caladium indoor plants, you would want to place them in a room with adequate protection from the harsh rays of the sun. If you can’t regulate the intensity of sunlight the plant gets, you can make use of a light curtain to shield the plant. 

Caladium Water Requirement

The watering done on caladium plants should be done according to their growth stage. When it first develops leaves(which is in the summer ), ensure you water the plant once a week. Keep the soil moist not soggy and never let it dry out,

During the winter season, the plant falls into dormancy so stop watering at this point and resume during the springtime when the plant should be active again. 

Avoid using cold water when watering the exotic plant and ensure that only dechlorinated water is used. 

Caladium Soil Requirement

Caladium Soil Requirement

When planting caladiums, you should ensure that whatever soil type is being used is both well-draining and rich. 

To achieve this, mix one part potting soil, one part peat, and a little organic compost. Test the soil draining ability by pouring a little water into the mix, if it ends up muddy then more peat would be required. 

Keep the pH level of the soil between a little acidic and neutral and the pH value should be between 5.5 and 6. 1 

Caladium Humidity and Temperature Requirement

Humidity is an important aspect of Caladium plant care. The Caladium loves proper exposure to high humidity levels, so do ensure you meet such requirements indoors.
