How to Care for Caladiums in Pots | Planting To Dormancy

Caladiums in pots thrive with bright filtered light, consistently moist well-drained soil, and warm temperatures above 60°F.

Getting caladiums in pots to look their best comes down to matching their tropical origins: warm air, bright shade, and steady moisture without sogginess. Nail those three, and the colorful arrow-shaped leaves carry a porch or windowsill from late spring through fall. The routine runs from proper planting depth to knowing exactly when to stop watering in autumn, and each step is simple once you know what the plant is asking for.

What Kind Of Pot And Soil Do Caladiums Need?

Choose a container with drainage holes first — that is non-negotiable. A pot wider than it is deep suits caladiums’ spreading root habit, and an 8- to 12-inch pot holds one or several tubers comfortably. Terra cotta and plastic both work; terra cotta dries faster, so plastic is more forgiving if you tend to forget watering.

Fill the pot with a commercial container potting mix rather than garden soil. Heavy, water-retentive soil traps moisture around the tuber and invites rot, which is the fastest way to lose a caladium. UF/IFAS Gardening Solutions puts it plainly: the soil should stay moist to the touch, never bone dry and never saturated.

How Deep Do You Plant Caladium Tubers In A Pot?

Plant tubers 1 to 2 inches deep with the knobby side — the eyes — facing up. Getting the orientation wrong is the most common beginner mistake; upside-down tubers still grow, but they waste weeks finding the surface.

When planting several tubers in one container, space them 6 to 8 inches apart so mature leaves have room to fill out without smothering each other. Plant only after night temperatures stay reliably above 60°F and the soil has warmed; cold soil slows sprouting and can rot the tuber before growth begins. Indoors, that means waiting until the growing season or keeping the pot in a warm, bright spot.

The Daily Care Routine: Light, Water, And Food

Caladiums want bright filtered light — roughly four to six hours of gentle morning or dappled sun daily. Full midday sun scorches the thin leaves, while deep shade turns them leggy and washes out their color. Indoors, a bright east-facing window or a few feet back from a south window works well, especially with added humidity.

Water when the top inch of soil dries, then soak until it runs from the drainage holes. Never let the pot sit in a saucer of standing water. These are tropical plants that also appreciate humidity — around 60% is ideal — so a pebble tray or nearby humidifier helps indoor pots between waterings.

Feed only after new leaves emerge. Classic Caladiums recommends a balanced liquid fertilizer diluted to half strength every other week during active growth. Other growers feed every two to six weeks, so the exact interval matters less than consistency — just don’t fertilize a dormant or freshly planted tuber. If you’re comparing products, our tested roundup of caladium fertilizers covers which formulations actually deliver balanced nutrition without burning tender roots.

Pinch off faded or damaged leaves at the base to keep the plant tidy and redirect energy into new growth. That’s the only pruning caladiums need.

When Do Caladiums Go Dormant And How Do You Store Them?

Caladiums are frost-tender, so the first frost blackens their foliage and triggers dormancy. Let the leaves die back naturally, then cut the plant down and stop watering entirely.

Store the pot dry in a dark, cool, frost-free spot — . The soil should stay completely dry until spring. Some growers lift and divide tubers at this stage, but leaving them in the pot works fine as long as the storage spot stays consistently cool and dark. In spring, bring the pot back into light, resume watering, and the cycle starts again.
