Calathea Lancifolia (Goeppertia lancifolia) is the tall, wavy calathea: long, narrow leaves with rippled edges, patterned with dark green spots on a lighter green background, and a deep purple underside. It grows upright and full, and it is one of the faster-growing calatheas — a young plant fills out into a lush clump within a season or two.

This guide covers everything Calathea Lancifolia needs: light, water, humidity, temperature, soil, repotting, feeding and the problems that show up when something is off. The care facts come from our plant database. It is a vigorous grower by calathea standards, but it still wants the family's essentials: gentle indirect light, soil that stays lightly moist, soft water and humid air. Keep it out of direct sun and draughts and it will reward you with a steady stream of new wavy leaves.

Light

Medium indirect light is what a calathea lancifolia wants — the soft, filtered light of a rainforest floor, not the direct sun of a windowsill. A spot near an east-facing window, which gives gentle morning light, usually suits it perfectly. A south- or west-facing window works too, as long as the plant sits well back from the glass or behind a sheer curtain; a few hours of direct sun will fade the pattern and crisp the leaf edges.

The leaves will tell you if the light is wrong. Washed-out, faded patterns point to too much sun, while leggy stems and dull, greenish leaves point to too little. Rotate the pot a quarter turn every couple of weeks so the plant grows evenly towards the light. If your only spot is dim, a grow light helps — our grow-light calculator can work out how many hours your plant needs.

Watering

Water weekly and keep the soil lightly moist — never soggy, never bone dry. Push a finger into the soil: if the top feels dry, water thoroughly until it runs from the drainage holes; if it still feels damp, wait. A calathea that dries out completely will curl its leaves and crisp at the edges, and it recovers slowly, so small, regular waterings beat occasional drenchings followed by drought.

Use soft water if you can. This plant is famously sensitive to tap-water salts, and brown leaf edges are often a water-quality problem rather than a watering-frequency problem. Rainwater is ideal, distilled or filtered water is a good substitute, and tap water left standing overnight is better than straight from the tap. Our watering calculator gives a starting amount for your pot size, and the watering schedule generator can turn it into a routine.

Humidity and temperature

This plant prefers high humidity and temperatures of 65–80°F (18–27°C). In practice that means two things to manage: warmth and moisture. Keep it away from cold draughts, cold windows and doors that open onto winter air, and away from radiators and heating vents that blast hot, dry air. A stable, warm room suits it far better than a spot that swings between hot and cold.

High humidity is not optional for a calathea — it is the difference between flawless leaves and brown, crispy edges. Aim for the humid end of household air: a small humidifier beside the plant is the most effective option, grouping plants together helps, and a pebble tray under the pot adds a little. Our humidity and temperature checker can tell you whether your room is humid enough, or whether a humidifier is the answer.

Soil and potting

A calathea lancifolia needs a mix that stays moist without staying wet: potting soil lightened with perlite and bark, with some coir or peat for moisture retention, in a pot with drainage holes. The balance matters — too dense and the roots suffocate, too airy and the soil dries out between your weekly waterings. Water should run through the pot when you water, but the mix should still feel lightly damp a few days later. Our potting-mix calculator can work out the proportions for your pot size.

Repotting

Repot every 1–2 years. The signs are roots circling out of the drainage holes, water running straight through without wetting the soil, or growth that has slowed even though light, water and humidity are right. Repot in spring, move up only one pot size, and settle the plant at the same depth in fresh mix. Repotting is also the moment to divide a large plant — see propagation below — and a good time to trim away any dead or damaged roots. Our repotting calculator can help you work out the next pot size.

Feeding

Feed lightly and only in the growing season: a balanced liquid houseplant fertiliser at half strength, once a month in spring and summer, and nothing in autumn and winter. More fertiliser is not better for a calathea — excess salts build up in the soil and burn the leaf edges, which is the last thing this plant needs. If the leaf tips brown even though humidity and water are right, flush the pot with plain soft water until it runs clear from the drainage holes.

Propagation

The reliable way to propagate a calathea lancifolia is division in spring. When you repot, look for natural separations in the root ball and gently pull or cut the plant into sections, making sure every section has healthy roots and a few leaves of its own. Pot each one in fresh, moisture-retentive mix, water well, and keep it warm and humid while it settles — a clear plastic bag over the pot for the first week or two helps. Leaf cuttings will not work for this plant; only division gives a new plant.

Common problems and fixes

Problem Likely cause Fix
Curling leaves Underwatering or low humidity See below
Fading patterns Too much direct sun See below
Yellow leaves Overwatering See below

Curling leaves

Likely cause: underwatering or low humidity. Curling is the plant's way of conserving moisture — it usually means the soil is dry or the air is too dry. Water if the soil needs it and raise the humidity around the plant; the leaves should uncurl once moisture returns.

Fading patterns

Likely cause: too much direct sun. Move the plant out of direct sun into bright indirect light. The faded leaves will not regain their pattern, but new leaves grown in gentler light should come through boldly patterned.

Yellow leaves

Likely cause: overwatering. Overwatering is the most common cause of yellow leaves. Let the top soil dry before watering again, make sure the pot has drainage holes and is not sitting in water, and trim away leaves that are fully yellow.

Frequently asked questions

How often should I water calathea lancifolia?

Weekly; keep soil lightly moist, never soggy. Always check the soil with a finger first rather than watering on a fixed day, because the interval changes with the season and pot size. Water thoroughly when the soil is dry and let the excess drain away.

How much light does calathea lancifolia need?

It needs medium indirect light. A spot near an east-facing window usually suits it well. Too little light gives slow, stretched growth and dull leaves; harsh direct sun can scorch the leaves.

Is calathea lancifolia safe for cats and dogs?

According to the data used for this guide, calathea lancifolia is non-toxic to cats and dogs.

When should I repot calathea lancifolia?

Repot every 1–2 years, or sooner if roots circle out of the drainage holes. Move up only one pot size, use fresh free-draining mix, and repot in spring.

Why are the tips of my calathea lancifolia browning?

Browning tips on a calathea lancifolia are usually caused by low humidity or by salts and minerals in tap water collecting at the leaf tips. Raise the humidity with a humidifier and water with rainwater, distilled water or tap water left out overnight. Flush the soil with plain soft water occasionally to wash out built-up salts, and trim brown tips with clean scissors if they bother you.
