Prayer plant brown leaf tips and edges: causes and what to do
6 results in the diagnosis tree begin with brown tips and edges, 3 of them marked likely when the answers fit. They are ordered here for Prayer plant (Maranta leuconeura), using what its sources say about humidity, soil moisture, cold tolerance, watering and feeding and one problem recorded for it.

Maranta leuconeura, widely known as the prayer plant due to its daily sunlight-dependent movements, is a species of flowering plant in the family Marantaceae native to the Brazilian tropical forests. It is a variable, rhizomatous perennial, growing to 30 cm (12 in) tall and broad, with crowded clumps of evergreen, strikingly-marked oval leaves, each up to 12 cm (5 in) long.

How this shows up on a Prayer plant
Leaf tips go crisp and brown
A narrow dry border on the prayer plant, often with a faint yellow line against the healthy tissue. It appears on several leaves at once rather than spreading from one.
Heated air holds less water than the plant loses into it, so moisture leaves the leaf faster than it arrives. Penn State Extension cites ASHRAE's indoor range of 30% to 60% relative humidity, and winter heating often takes a room below it.
Telling it apart: When it started. Edges that browned as the heating came on point at air; edges that browned through a wet summer do not.
Penn State Extension · read 13 September 2026Possible causes, likeliest first for a Prayer plant
Most likely cold
Ranked higher because Prayer plant's recorded problems point this way.
Its RHS hardiness rating puts this plant's cold floor at 10°C or above, so a cold windowsill at night is a strong explanation.
- H1B — 10–15°C RHS · read 13 September 2026
Why: Soft, dark patches rather than crisp ones are damaged tissue rather than dried tissue.
What to try:
- Move it away from the glass at night, or keep the curtain on the room side of the prayer plant.
- Leave damaged leaves until new growth appears, then remove the worst of them.
What would settle it: Where the prayer plant sits at night, and what the glass feels like at that hour. Damage that appeared after one cold night, on the side facing the window, is the pattern.
Most likely too little water
Ranked higher because Prayer plant's recorded problems point this way.
- Moist but well-drained or Well-drained RHS · read 13 September 2026
Why: Soil dry two inches down leaves the roots nothing to send up, and the leaf edges are the last tissue in line.
What to try:
- Water thoroughly, until it runs from the drainage hole.Useful: pot with drainage holes
- Check the soil with a finger every few days rather than watering on a fixed day.Useful: moisture meter
What would settle it: Water it thoroughly and watch the next new leaves. If they come in with clean edges under steadier watering, the edges were thirst.
Most likely a build-up of salts in the soil
- Chalk, Clay, Loam, Sand; pH Acid or Alkaline or Neutral RHS · read 13 September 2026
Why: Minerals from tap water and fertiliser are left behind as water evaporates, and a white crust on the compost or the pot rim is where they show.
What to try:
- Water slowly and heavily until several times the pot's volume has run through the drainage hole, to wash the salts out.Useful: pot with drainage holes
- Scrape off the top layer of crusted compost and replace it.
What would settle it: Scrape the crust. If it is gritty and dissolves in water it is mineral; if it is fluffy it is mould, which is a different problem.
Less likely for a Prayer plant, still possible

What this does not cover
This page orders a decision tree's results using a plant's sourced care. It has not seen your plant, its pot or its window, and two problems at once are common: that is the usual reason a confident answer turns out wrong. The questions in the diagnosis tool narrow it further than a list can.
