About Remusatia vivipara

Remusatia vivipara · also called viviparous elephant ear, sky taro · tropical

Remusatia vivipara is a tuberous tropical aroid famous for the hooked bulbils it produces on whip-like stalks, which catch onto passing animals to disperse. It grows as an epiphyte or lithophyte across Asia and Africa, pushing out heart-shaped leaves in the wet season then dying back to a dormant tuber in the dry season.

Mature size: Leaves on stalks roughly 30-60 cm tall; overall clump up to about 60 cm in active growth.

Watch for — Sudden leaf die-back: Often natural seasonal dormancy rather than disease. Don't discard the pot; reduce water and resume care when new growth appears.

How to tell remusatia vivipara needs repotting

Repotting on a calendar is less reliable than reading the plant. For remusatia vivipara, 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 remusatia vivipara 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 remusatia vivipara

Lift and divide every 3–4 years once clumps congest. Rather than a true repot, remusatia vivipara is lifted and divided once the clump congests and flowering drops off. Seasonally dormant tuberous perennial herb; epiphytic or lithophytic, producing heart-shaped leaves and distinctive bulbil-bearing stalks before dying back to the tuber..

What size pot to step remusatia vivipara up to

Pot size matters less than depth and spacing here. When you replant remusatia vivipara, 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.

Not sure of the exact diameter? Our pot size calculator takes the current pot and root spread and tells you the right next size — it deliberately recommends a single step up, never a big jump.

The best time of year to repot remusatia vivipara

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 remusatia vivipara in full growth or flower sets it back badly.

Step-by-step: repotting remusatia vivipara

Wait for dormancy. Let remusatia vivipara 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 free-draining, humus-rich aroid or epiphyte 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 remusatia vivipara, 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 remusatia vivipara

Remusatia vivipara wants free-draining, humus-rich aroid or epiphyte mix. Use a chunky, airy blend of orchid bark, perlite, coir and a little compost. Good drainage is essential because the tuber rots in dense, soggy soil. As an epiphyte it also grows mounted on bark or in a coarse, well-aerated container. Always use fresh mix when you repot — reusing old, broken-down soil reintroduces the compaction and poor drainage you are repotting to fix.

Repotting remusatia vivipara — frequently asked questions

How often should you repot remusatia vivipara?

Lift and divide every 3–4 years once clumps congest for remusatia vivipara. Remusatia vivipara 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 free-draining, humus-rich aroid or epiphyte mix. Crowding, not pot size, is what reduces flowering over time.

What size pot does remusatia vivipara need?

When is the best time of year to repot remusatia vivipara?

Do you "repot" remusatia vivipara, or lift and divide it?

You lift and divide it. Remusatia vivipara 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 remusatia vivipara after repotting?

Hold off feeding remusatia vivipara 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.
