Peacock Plant (Calathea makoyana) care

Light

Picture the indirect light an east-facing window gives mid-morning — that's the brightness peacock plant grows fastest in. Give it bright but filtered or indirect light, ideally near a north or east window. Direct sun bleaches and scorches the patterned leaves, while deep shade dulls the markings and slows growth. It tolerates lower light better than many houseplants but keeps its best colour in moderate, even brightness. You'll know it's right when new leaves come out the same size and colour as the established ones. Smaller, paler new leaves = move closer to the window.

Watering

Aim for when the top 2-3 cm of compost dries; roughly weekly for peacock plant, but treat that as a starting point rather than a rule. A south-facing summer windowsill will dry the pot twice as fast as a north-facing winter room. Lift the pot; if it feels noticeably lighter than it did wet, water it. Keep the compost evenly moist but never soggy, watering when the top few centimetres feel dry and letting excess drain away fully. Use rainwater, distilled or filtered water at room temperature, because fluoride and chlorine in tap water cause leaf-edge browning. Reduce watering in winter and never let the plant sit in standing water, which triggers root rot.

Soil and pot

Peacock Plant grows best in 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. A pot with a working drainage hole is non-negotiable for this species — even free-draining mix will turn soggy in a closed planter. If you love the look of a decorative pot without a hole, use it as a cachepot around an inner nursery pot you can lift out to water.

Humidity and temperature

Peacock Plant sits happiest at around 60-80% humidity and 18-27°C (65-80°F). This is a humidity-hungry rainforest plant; aim for 60% or higher. In dry centrally heated rooms run a humidifier, stand the pot on a pebble-and-water tray, or group it with other plants. Low humidity is the most common cause of crispy, curling or browning leaf edges. If you keep the room above 18 year-round and avoid placing the plant near a cold draught, a hot radiator, or an air-conditioning vent, you have already handled the two biggest indoor stressors.

Fertilising

Feed peacock plant sparingly. Feed every 2-4 weeks during spring and summer with a balanced liquid houseplant fertiliser diluted to roughly half strength. Stop or greatly reduce feeding in autumn and winter when growth slows. This plant is sensitive to fertiliser salt build-up, so flush the compost with clean water occasionally and avoid overfeeding, which scorches leaf tips. Skip fertiliser entirely on a stressed, recently-repotted, or actively wilting plant — fertiliser salts make damage worse, not better. Wait for a round of healthy new growth before resuming a feeding rhythm.

Common problems

Below are the issues we see most often on peacock plant in the Growli community. Each is annotated with the most common cause so you know where to start.

• Brown, crispy leaf edges — Usually caused by low humidity, dry air or fluoride/chlorine in tap water. Raise humidity to 60%+ and switch to rainwater, distilled or filtered water.
• Curling or rolling leaves — A sign of underwatering, very low humidity or cold draughts. Check the compost is evenly moist and move the plant away from radiators, vents and cold windows.
• Faded or scorched markings — Direct sun bleaches and burns the patterned foliage. Move to bright, indirect or filtered light to restore the contrast.
• Spider mites and other sap-suckers — Dry indoor air invites spider mites, plus aphids, scale and mealybugs. Inspect leaf undersides regularly, wipe foliage and treat early with insecticidal soap or neem.

Propagation

Propagate by division in late spring or early summer. Tip the plant from its pot and gently tease the rhizome clump into sections, each with healthy roots and several leaves, then pot each piece into fresh moist compost. Keep divisions warm, humid and out of direct sun while they re-establish. Propagation is the cheapest, most satisfying way to expand a collection — and it doubles as insurance against losing a mature plant to an accident. Take a backup cutting once the parent is established and healthy.

Toxicity to pets

Peacock Plant is pet-safe. The ASPCA lists Calathea (Calathea spp., family Marantaceae) as non-toxic to cats, dogs and horses, and the peacock plant belongs to this group. North Carolina Extension also classes Goeppertia makoyana as non-toxic. As with any houseplant, a pet that eats a large quantity of the fibrous leaves may get a mild, transient stomach upset, but no toxic compounds are involved. If you keep cats, dogs, or curious children in the house, weigh placement carefully — a high shelf or a hanging planter is enough for casual safety. For severe ingestion incidents, call your local vet and the ASPCA Animal Poison Control Center (in the US, 888-426-4435).

Pet-safety status is sourced from the ASPCA Toxic and Non-Toxic Plant List, which catalogues the most-asked-about plants for cats, dogs, and horses.
