About Peacock Plant

Goeppertia makoyana · also called Peacock plant, Calathea makoyana · houseplant

The peacock plant (Goeppertia makoyana, formerly Calathea makoyana) is a tropical foliage houseplant prized for its translucent, paint-stroked leaves that fold up at night. Its defining care need is consistently high humidity paired with warm, draught-free conditions and soft water, as fluoride in tap water and dry air both scorch the foliage.

Mature size: Typically 30-60 cm (1-2 ft) tall and around 20-30 cm (8-12 in) wide as a houseplant.

How to tell peacock plant needs repotting

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

Roots spiralling thickly out of the drainage holes or pushing the whole plant up out of the pot.
The pot is so packed that water runs straight through in seconds and barely wets the soil.
It has split a plastic pot, or the rootball is a solid mass with almost no soil left when you slide it out.
Growth and (for peacock plant) flowering have clearly stalled despite good light and feeding — but remember this plant likes being snug, so a little crowding alone is not a reason to repot.

For the underlying biology of a pot-bound root system and why it stalls a plant, see our guide to spotting and fixing a root-bound plant.

How often to repot peacock plant

Only every 2–4 years, when genuinely crowded. Peacock Plant is one of the plants that genuinely prefers a snug pot — it grows and flowers better with its roots a little restricted, so resist the urge to repot it on schedule. A clumping, evergreen perennial with an upright, bushy habit that spreads slowly from underground rhizomes. New leaves emerge rolled and unfurl from the centre, and the foliage performs nyctinasty, rising and folding upward at night to reveal the purple-red undersides..

What size pot to step peacock plant up to

Go up only one pot size — roughly 2–3 cm (about an inch) wider in diameter, no more. Peacock Plant positively prefers a snug pot: it flowers and grows better when the roots are a little restricted. The single biggest repotting mistake here is over-potting — dropping peacock plant into a pot two or three sizes up. All that surplus soil holds water the small root system cannot use, stays cold and wet, and rots the roots within weeks. When in doubt, choose the smaller pot.

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 peacock plant

Early spring, just as new growth restarts, is the ideal window for peacock plant. The plant is moving into its strongest growth phase and re-roots into fresh soil quickly. Avoid repotting in winter dormancy or, for flowering plants, while it is in bud or bloom — recovery is slowest then and you risk dropping the flowers.

Step-by-step: repotting peacock plant

Confirm it actually needs it. Slide peacock plant out and check the roots. Only continue if it is genuinely packed — this plant prefers a snug pot, so if there is still soil and room, put it straight back.
Pick a pot only one size up. Choose a pot just 2–3 cm wider with good drainage. Resist anything bigger; over-potting is the main killer here.
Ease it out gently. Water lightly the day before, then tip peacock plant out, supporting the base. Tease the outer roots free only enough to stop them circling.
Repot at the same depth. Add a layer of fresh peat-free, free-draining houseplant mix high in organic matter, set the plant so the soil line sits exactly where it did before, and backfill around the sides, firming lightly.
Settle it in. Water once to settle the soil, then let it sit. Hold off on more water until the top of the soil dries — fresh soil around a small root system stays wet for a while.

Aftercare

Because the new soil holds more water than the old crammed rootball did, ease right back on watering — let the top of the soil dry before you water peacock plant again, or you will rot the roots in the very pot you just moved it to. Keep it out of harsh direct sun for a fortnight. Do not fertilise for about 4 weeks — fresh mix already carries nutrients and feeding freshly disturbed roots scorches them.

The right soil mix for peacock plant

Peacock Plant wants peat-free, free-draining houseplant mix high in organic matter. Use a light, moisture-retentive but well-aerated mix, such as two parts peat-free houseplant compost to one part perlite, with a little orchid bark or coir to keep it open. The roots need air and must never sit waterlogged. A pot with drainage holes is essential. Always use fresh mix when you repot — reusing old, broken-down soil reintroduces the compaction and poor drainage you are repotting to fix.

Repotting peacock plant — frequently asked questions

How often should you repot peacock plant?

Only every 2–4 years, when genuinely crowded for peacock plant. Only repot peacock plant every 2–4 years, and only when it is genuinely root-bound — it flowers and grows best slightly crowded. Step up just one pot size in spring using peat-free, free-draining houseplant mix high in organic matter. The key mistake is over-potting: a too-big pot stays wet and rots the roots.

What size pot does peacock plant need?

When is the best time of year to repot peacock plant?

Does peacock plant like to be root-bound?

Yes — peacock plant genuinely flowers and grows best when slightly pot-bound, so do not rush to repot it. The mistake to avoid is over-potting into a much larger pot: the excess soil stays wet, the roots cannot use it, and the plant rots. Only repot every few years and only one snug size up.

Should you fertilise peacock plant after repotting?

Not immediately. Wait about 4 weeks after repotting peacock plant. Fresh mix already contains nutrients, and feeding freshly cut or disturbed roots burns them. Resume your normal feeding routine once you see new growth.
