What Snake plant’s sources say that bears on this

Humidity
ASHRAE recommends indoor relative humidity between 30% and 60%

Soil moisture

RHS · read 11 September 2026
Cold tolerance
H1C — 5–10°C
RHS · read 11 September 2026
Watering
It needs soil that drains well and careful watering; avoid overwatering, which rots the roots. From spring to autumn, let the soil dry between waterings.

How this shows up on a Snake plant

Brown brittle margins with a green centre

On a snake plant the browning starts furthest from the midrib and works inward, and it crumbles rather than smears. The centre of each blade is untouched.

Leaf margins are the end of the water supply, so they are the first tissue to run short when the air takes more than the roots can send. Penn State Extension cites 30% to 60% as the recommended indoor range, and a heated room in winter sits below it.

Telling it apart: Whether the soil is dry too. Crisp edges with damp soil point at the air; with dry soil, at the watering.

Possible causes, likeliest first for a Snake plant

  1. Most likely cold

    Ranked higher because Snake plant's recorded problems point this way.

    • H1C — 5–10°C RHS · read 11 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 snake plant.
    • Leave damaged leaves until new growth appears, then remove the worst of them.

    What would settle it: Where the snake 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.

    Check this with the questions

  2. Most likely a build-up of salts in the soil

    • Loam, Sand; pH Alkaline or Neutral RHS · read 11 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.

    Check this with the questions

  3. Most likely too little water

    Ranked lower for Snake plant because of what its sources say.

    Its source describes well-drained soil for this plant, so soil that dries between waterings is expected. The concern is soil left dry long enough for the plant to go limp or wrinkle.

    • Well-drained RHS · read 11 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.

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.
