Plant Care
-
Light
Caladiums grow best in bright, indirect light or partial shade. Most varieties thrive with gentle morning sun but should be protected from intense afternoon sunlight, which can scorch their colourful leaves. Indoors, place them near a bright window with filtered light for the best foliage colour.
-
Temperature
Caladiums are tropical plants that prefer temperatures between 18–30°C (65–86°F). They are highly sensitive to cold and should be protected from temperatures below 15°C (59°F). Warm, stable conditions encourage vigorous growth throughout the growing season.
-
Water
Keep the soil consistently moist but not soggy during active growth. Water when the top 2–3 cm (about 1 inch) of soil begins to dry, ensuring excess water drains away. Reduce watering once the foliage naturally dies back as the plant enters dormancy.
-
Humidity
Caladiums prefer high humidity of 60% or more, although they can adapt to average household humidity. Higher humidity helps maintain vibrant foliage and reduces the risk of crispy leaf edges. Indoor plants benefit from humidifiers or grouping with other tropical plants.
-
Potting Mix
Plant Caladiums in a light, rich, well-draining potting mix that retains moisture without becoming waterlogged. A blend containing quality potting mix, coco coir or peat moss, and perlite provides the ideal balance of drainage and water retention.
-
Fertilizer
Feed Caladiums with a balanced liquid fertiliser every 2–4 weeks during the growing season, or apply a slow-release fertiliser in spring. Stop fertilising when the plant begins to enter dormancy, as it will not actively use the nutrients until new growth resumes.
