About Caladium Florida Cardinal

Caladium 'Florida Cardinal' · also called Florida Cardinal caladium · tropical

A fancy-leaved caladium grown for dramatic heart-shaped leaves with deep cardinal-red centres and contrasting green margins. This tuberous tropical thrives in warmth, humidity and bright filtered light, going dormant in cool months. As a Caladium and member of the Araceae, it is toxic to cats and dogs through insoluble calcium oxalates.

Mature size: Typically 30-60 cm tall and 30-45 cm wide, with showy leaves reaching 15-30 cm long depending on growing conditions.

Watch for — Slow or no sprouting: Usually soil that is too cool; caladiums need warmth around 21°C or more to break dormancy. Start tubers in a warm spot and be patient.

How to tell caladium florida cardinal needs repotting

Repotting on a calendar is less reliable than reading the plant. For caladium florida cardinal, watch for these signs:

Flowering has tailed off year on year and the clump has become congested and overcrowded.
Lots of leaf and few flowers — a classic sign that caladium florida cardinal bulbs or tubers need lifting and dividing.
Bulbs visibly bursting the pot or pushing each other to the surface.
It is the natural dormancy window (foliage yellowed and died back) — the only safe time to lift and split.

How often to repot caladium florida cardinal

Lift and divide every 3–4 years once clumps congest. Rather than a true repot, caladium florida cardinal is lifted and divided once the clump congests and flowering drops off. Tuberous, clump-forming deciduous perennial that pushes up long-stalked, paper-thin heart-shaped leaves in spring and summer, then dies back to a dormant tuber in cooler months. It does not climb or trail; foliage emerges directly from the tuber..

What size pot to step caladium florida cardinal up to

Pot size matters less than depth and spacing here. When you replant caladium florida cardinal, set the bulbs or tubers at the correct depth (a rough guide: two to three times their own height of soil over the top) and space them so they are not touching. A wide, shallow pot suits a clump better than a tall narrow one.

The best time of year to repot caladium florida cardinal

The only safe window is dormancy: wait until the foliage has yellowed and died back naturally, lift and divide then, and replant before or at the start of the next growing season. Disturbing caladium florida cardinal in full growth or flower sets it back badly.

Step-by-step: repotting caladium florida cardinal

Wait for dormancy. Let caladium florida cardinal foliage yellow and die back completely. Lifting while it is in growth wastes the energy it is storing for next year.
Lift carefully. Loosen the soil well away from the bulbs/tubers with a fork and ease the whole clump out without spearing them.
Separate the offsets. Gently pull the clump apart into individual bulbs or tubers. Keep only firm, healthy, blemish-free ones.
Replant at the right depth. Reset them in fresh rich, moisture-retentive yet well-draining mix at the correct depth and spacing — not touching — so each has room to bulk up.
Water in and rest. Water once to settle them, then keep on the dry side until growth resumes. Do not feed until leaves are actively growing.

Aftercare

After replanting caladium florida cardinal, keep the soil barely moist — not wet — until shoots appear; bulbs and tubers rot in cold, saturated soil. Once leaves are growing strongly, resume normal watering. Hold off feeding until the plant is in active growth again.

The right soil mix for caladium florida cardinal

Caladium Florida Cardinal wants rich, moisture-retentive yet well-draining mix. Use a fertile, organic-rich potting mix with added perlite or coarse sand for drainage, ideally slightly acidic. The medium should hold moisture during growth but never stay sodden, which rots the tuber. Plant tubers a few centimetres deep, knobbly side up. Always use fresh mix when you repot — reusing old, broken-down soil reintroduces the compaction and poor drainage you are repotting to fix.

Repotting caladium florida cardinal — frequently asked questions

How often should you repot caladium florida cardinal?

Lift and divide every 3–4 years once clumps congest for caladium florida cardinal. Caladium Florida Cardinal is lifted and divided, not "repotted". Every 3–4 years, once the foliage has died back and it is dormant, lift the clump, separate the offsets, and replant at the correct depth in rich, moisture-retentive yet well-draining mix. Crowding, not pot size, is what reduces flowering over time.

What size pot does caladium florida cardinal need?

When is the best time of year to repot caladium florida cardinal?

Do you "repot" caladium florida cardinal, or lift and divide it?

You lift and divide it. Caladium Florida Cardinal grows from bulbs or tubers, so instead of repotting you wait for dormancy, lift the congested clump, separate the healthy offsets, and replant them at the right depth and spacing. Doing this every 3–4 years restores flowering.

Should you fertilise caladium florida cardinal after repotting?

Hold off feeding caladium florida cardinal until it is in active growth again. Fresh soil already carries enough nutrients to get it re-established, and feeding disturbed roots too soon does more harm than good.
