Lady palm: brown crispy edges
Why are the leaf edges brown and crisp?
On lady palm, the likeliest cause is too much direct sun. Browning on the leaves nearest the glass, and on the sun-facing half of individual leaves, rather than uniformly round the margin.
- 1Too much direct sun
Ranked here because its ceiling is bright-indirect light, so direct afternoon sun through glass will scorch it.
How to tell. Browning on the leaves nearest the glass, and on the sun-facing half of individual leaves, rather than uniformly round the margin.
What to do. Move it back from the window or filter the light. Scorched tissue does not recover; you are protecting new growth.
- 2Air too dry
Ranked here because indoor air in winter is drier than most houseplants prefer.
How to tell. Browning follows the leaf margin evenly all the way round, with a thin yellow band between brown and green. Worst in winter when heating is on.
What to do. Group plants together, or run a humidifier nearby. Misting raises humidity for about ten minutes and is not a fix.
- 3Watering too little, or too erratically
How to tell. The pot is light, the soil has shrunk from the sides, and the browning is worst on the leaves furthest from the stem.
What to do. Water thoroughly rather than often. A small splash wets the top inch and never reaches the roots doing the work.
- 4Minerals in tap water
How to tell. Tips brown first and the edge follows, on a plant that is otherwise healthy and correctly watered. A white crust on the soil surface or pot rim confirms it.
What to do. Switch to filtered or rainwater, or leave tap water standing overnight. Flush the pot thoroughly every few months to wash salts out.
- 5Fertiliser salts
How to tell. Brown tips plus a visible white crust on the soil or pot rim, on a plant fed more than monthly.
What to do. Flush the pot with several pot-volumes of water and feed at half strength, at most monthly in growth.
Why that order, for this plant
The ranking above is not a generic list. It is computed from this species' own record — a watering interval of 8–14 days, a tropical understory origin, a humidity floor of 40%, and a light range from low to bright-indirect. Change those figures and the order changes with them.
That is the whole point of a per-species page. Brown crispy edges on a plant watered every three days and brown crispy edges on one watered every three weeks almost never have the same cause, and a list that ranks them identically is worth nothing to either owner. You can check the reasoning against the care fields on the species entry, which is where these numbers come from.
No percentages appear on this page. We have not run a grower survey, and a confident-sounding figure with no dataset behind it is worse than none. Order and distinguishing tests are what we can honestly give.
