2. Choosing a Planting Location

Caladiums prefer partial shade or filtered sunlight. Select a location that receives indirect or dappled light, as direct sunlight can scorch the leaves. They also thrive in well-draining soil with high organic matter content.

3. Preparing the Soil

Prepare the soil by loosening it with a garden fork or tiller. Add compost or well-rotted organic matter to improve soil fertility and drainage. Caladiums prefer slightly acidic to neutral soil with a pH range of 5.5 to 7.0.

5. Watering

After planting, water the caladium bulbs thoroughly to settle the soil. Keep the soil consistently moist throughout the growing season, but avoid overwatering, as it can lead to bulb rot. Water deeply when the top inch of soil feels dry, but allow the soil to drain properly.

6. Mulching

Apply a layer of organic mulch, such as wood chips or straw, around the base of the plants. Mulch helps conserve soil moisture and regulates soil temperature. It also suppresses weed growth.

7. Fertilizing

Caladiums benefit from regular feeding. Apply a balanced, slow-release fertilizer according to the package instructions. Alternatively, you can use a water-soluble fertilizer every two to three weeks during the growing season. Avoid over-fertilizing, as it can burn the foliage.

8. Providing Adequate Humidity

Caladiums thrive in humid conditions. If your climate is dry, you can increase humidity by misting the leaves with water or placing a tray of water near the plants. Grouping caladiums together can also create a microclimate with higher humidity.

9. Maintenance

Remove any yellow or dead leaves as they appear to maintain the plant’s appearance. If any flowers develop, you can pinch them off to direct the plant’s energy into leaf growth.

10. Winter Care

In colder regions, caladiums are usually treated as annuals or lifted and stored indoors during winter. As the foliage starts to die back in autumn, stop watering and allow the leaves to dry out. Carefully dig up the bulbs, remove excess soil, and store them in a cool, dry location (around 50 to 60°F or 10 to 15°C) for the winter. Replant them in spring after the danger of frost has passed.
