About Colocasia Burgundy Stem

Colocasia esculenta 'Burgundy Stem' · also called Burgundy Stem taro, burgundy elephant ear · tropical

Colocasia esculenta 'Burgundy Stem' is a bold elephant ear with large heart-shaped green leaves on deep wine-red petioles. Unlike alocasias, it is a thirsty bog plant that loves constant moisture, full sun to part shade, rich soil and heat. Vigorous in summer, it dies back in cold. Toxic to cats and dogs like all Colocasia.

Mature size: Reaches 1-1.5 m tall with leaves 40-60 cm long in a good season.

How to tell colocasia burgundy stem needs repotting

Repotting on a calendar is less reliable than reading the plant. For colocasia burgundy stem, 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 colocasia burgundy stem 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 colocasia burgundy stem

Lift and divide every 3–4 years once clumps congest. Rather than a true repot, colocasia burgundy stem is lifted and divided once the clump congests and flowering drops off. Vigorous clumping tuberous perennial sending up large heart-shaped leaves on tall coloured petioles from a central corm..

What size pot to step colocasia burgundy stem up to

Pot size matters less than depth and spacing here. When you replant colocasia burgundy stem, 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 colocasia burgundy stem

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 colocasia burgundy stem in full growth or flower sets it back badly.

Step-by-step: repotting colocasia burgundy stem

Wait for dormancy. Let colocasia burgundy stem 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, heavy, moisture-retentive soil 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 colocasia burgundy stem, 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 colocasia burgundy stem

Colocasia Burgundy Stem wants rich, heavy, moisture-retentive soil. Unlike airy aroid mixes, Colocasia wants a fertile, water-holding loam high in organic matter. Heavy soil that stays wet is ideal; it tolerates poor drainage far better than any Alocasia. Always use fresh mix when you repot — reusing old, broken-down soil reintroduces the compaction and poor drainage you are repotting to fix.

Repotting colocasia burgundy stem — frequently asked questions

How often should you repot colocasia burgundy stem?

Lift and divide every 3–4 years once clumps congest for colocasia burgundy stem. Colocasia Burgundy Stem 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, heavy, moisture-retentive soil. Crowding, not pot size, is what reduces flowering over time.

What size pot does colocasia burgundy stem need?

When is the best time of year to repot colocasia burgundy stem?

Do you "repot" colocasia burgundy stem, or lift and divide it?

You lift and divide it. Colocasia Burgundy Stem 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 colocasia burgundy stem after repotting?

Hold off feeding colocasia burgundy stem 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.
