How this shows up on a Olive
Brown, papery patches on the leaves nearest the glass
Scorched leaves on the olive turn from pale to brown and brittle, and the damage stops where the shade of another leaf fell across it.
Even a plant described as full sun can take more through glass than it would outdoors, because glass removes the breeze that carried the heat away.
Telling it apart: Whether the patches grow. Scorch is done once it happens; a leaf spot keeps spreading.
RHS · read 13 September 2026Leaves bruised and browned along the edges after a gale
After a windy spell the olive shows dry brown edges and torn leaves on its exposed side. New growth that follows is undamaged if the weather settles.
RHS describes it as needing shelter. Moving air dries leaf surfaces quickly and bruises soft tissue, so a canopy in a windy spot is marked on the side the wind reaches.
Telling it apart: Timing. Damage that appeared after one windy day is weather; damage that builds slowly is water or roots.
RHS · read 13 September 2026Possible causes, likeliest first for a Olive
Most likely too little water
Ranked higher because Olive's recorded problems point this way.
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 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.
Most likely cold
Ranked lower for Olive because of what its sources say.
Its RHS hardiness rating puts this plant's cold floor at or below freezing, so cold damage in a heated room is unlikely. A frost outdoors, or a night in a cold car, is another matter.
- H4 — -10 to -5°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 olive.
- Leave damaged leaves until new growth appears, then remove the worst of them.
What would settle it: Where the olive 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.
Less likely for a Olive, 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.
