How to take care of potted caladiums?
Container-grown outdoor Caladiums may need to be watered every day during peak summer temperatures; if they’re in a garden bed, you can water them less often if you spread a layer of mulch across the soil surface. Fertilize monthly from April until September, and when the foliage has died down, cut it off. Caladiums also like Epsom salt, so you can water them in with Epsom salt dissolved in water, or sprinkle a bit over the soil at the time of planting.SOIL: Caladiums grow beautifully in containers and in landscapes that have well-drained soil.

What is the secret to growing caladiums?
When you first plant your caladiums, they’ll enjoy moist—not soggy—soil. The more sun they are growing in, the more quickly the soil will dry out, so you’ll want to keep an eye on them until they are established. Once they are rooted in and flourishing in your garden, they will only need average amounts of water. To keep your caladiums healthy and vibrant, feed them with a balanced, slow-release fertilizer every 4-6 weeks during the growing season. A 10-10-10 ratio fertilizer works well. Be careful not to over-fertilize, as this can lead to excessive leaf growth at the expense of the vibrant foliage colors.Caladiums don’t require pruning, but it can help the plant grow healthy and full. Trimming off dead or wilting leaves encourages new growth and keeps a consistent, vibrant look. It also improves air circulation, which keeps fungus at bay and allows more sunlight to reach the lower leaves.To help caladiums take in the perfect amount of water, try bottom watering—an ideal method for sensitive plants in small or medium-sized pots. Place the pot in a container filled with lukewarm water and let it sit for around 20 minutes. Then drain the water, let the pot drip-dry, then return it to its tray.Common Pests & Plant Diseases Though caladiums are relatively pest- and disease-free, they are susceptible to caterpillars, aphids, and slugs. Maintaining a healthy soil, proper light conditions, and watering balance will help prevent infestations. Aphids chew small holes in the foliage.
What is the lifespan of a caladium?
The average lifespan of Caladium Candidum plants extends from 1-2 years when grown outdoors in zones 9-11 but their tubers survive indefinitely when properly stored during winter months. The indoor container cultivation of Caladium Candidum plants works well for home environments. Caladiums thrive in the hot and humid conditions of summer but will start to droop and lose leaves as temperatures cool. If the tubers are to be kept over the winter in temperate areas, they must be brought in before the first frost (or before soil temperatures drop below 55ºF).For a quicker display of color, caladium tubers can be pre-sprouted indoors. Start them about 4-6 weeks before you will be moving them outdoors. Plant the tubers in barely moist growing mix and keep them warm (70-75°) day and night. Caladium tubers are usually planted approximately 6 apart.Do you have to soak Caladium bulbs before planting? Although this is not necessary, you can soak your corms for about an hour in warm water before planting. This would be beneficial if your corms have dried out too much.If you wish to grow caladiums exclusively as indoor plants, there are certain conditions you can and must create for them.

Caladium tubers are hardy in zones 8-12 and do not need any special care to survive the winter. As the plants enter dormancy in late summer or early fall, the leaves will droop and eventually wither. Simply leave the tubers in the ground where they are and wait for the plants to re-emerge in spring. Fertilizing: Caladiums benefit from regular feeding. Use a balanced, water-soluble fertilizer every 4-6 weeks during the growing season. Pinching: If you want bushier plants, pinch off the center bud when the plants are about 4-6 inches tall.
