Spider Plant: salt and fluoride buildup — what does it look like?

Sharp brown tips on otherwise healthy green leaves. White crust on the soil surface or pot rim. Flush the pot thoroughly with distilled water. Trim tips to a point. Cosmetic, not terminal.

Spider Plant: root rot — what does it look like?

Whole leaves yellowing from the base, crown going soft, water sitting in the pot. Spider plants have thick water-storing roots and genuinely resent constant wet. This is what kills them.

Spider Plant: severe pot binding — what does it look like?

Roots visibly filling the pot and lifting the plant. Dries out within a day of watering. Not fatal quickly, but it makes drought damage inevitable. Divide it.

What went wrong

Spider Plant

Chlorophytum comosum

Hard to kill, easy to make ugly.

Spider plants rarely die outright. What usually happens is that they develop brown crispy tips, their owner concludes something is seriously wrong, and a cascade of corrections follows — more water, then fertilizer, then a repot — until something actually does go wrong.

Brown tips on a spider plant are almost always fluoride and salt accumulation from tap water and fertilizer, not a disease. The plant is fine. It is just no longer pretty.

Usually one of these

3 Likely Causes

Ranked by how often it is actually this.

01
Salt and fluoride buildup
Nearly universal, rarely fatal
What you saw
Sharp brown tips on otherwise healthy green leaves. White crust on the soil surface or pot rim.
What it means
Flush the pot thoroughly with distilled water. Trim tips to a point. Cosmetic, not terminal.
02
Root rot
The actual killer
What you saw
Whole leaves yellowing from the base, crown going soft, water sitting in the pot.
What it means
Spider plants have thick water-storing roots and genuinely resent constant wet. This is what kills them.
03
Severe pot binding
Common in old plants
What you saw
Roots visibly filling the pot and lifting the plant. Dries out within a day of watering.
What it means
Not fatal quickly, but it makes drought damage inevitable. Divide it.

The question you actually have

Dead or dormant?

Look at the crown where the leaves meet the roots. Firm and white means alive even if every leaf is brown. Spider plants regrow readily from thick tuberous roots. And check for plantlets on any runner — those root easily and are functionally a backup copy of the plant.
