Spider plant brown tips usually come from dry winter air, tap water or fertilizer salts. Find your cause in the table and stop new tips fast.
Short answer: brown tips on a spider plant are almost always caused by water and air, not disease. The usual culprits are dry indoor air from heating, minerals and fluoride in tap water, fertilizer salt build-up, or uneven watering. Brown tips will not turn green again, but you can trim them off and stop new ones from forming within a few weeks.

Spider plants (Chlorophytum comosum) have long, thin leaves, and the tip is the part furthest from the roots. When water is short, the air is dry or salts build up in the leaf, the tip is the first place cells die. Match what you see in the table below.
| What you see | Most likely cause | First thing to do |
|---|---|---|
| Light brown, papery tips on many leaves, worse in winter | Dry air from heating | Raise humidity, move away from radiators and vents |
| Brown tips even though watering and humidity seem fine | Fluoride, chlorine or hard tap water | Switch to rainwater, distilled or filtered water |
| White crust on the soil or pot rim, brown tips after feeding | Fertilizer salt build-up | Flush the soil, cut back on fertilizer |
| Crispy tips plus limp, pale leaves and bone-dry soil | Underwatering | Water deeply, then check the soil more often |
| Dark brown or black tips, yellow leaves, soggy soil | Overwatering or root rot | Let the soil dry, check the roots |
| Brown patches or tips on leaves touching the window | Cold glass, drafts or direct sun scorch | Move the plant a little away from the window |
| Water runs straight through, roots poking out of the drainage holes | Rootbound plant | Repot into a pot 1–2 inches (2–5 cm) wider |
This is the most common reason spider plants get brown tips in the colder months. Furnaces, radiators and baseboard heaters dry the air in a room, and indoor humidity can drop well below what most houseplants like. The long leaf tips lose moisture faster than the roots can replace it, so they turn crispy and light brown.
How to fix it:
Spider plants are well known for being sensitive to fluoride, and they also react to chlorine and to the dissolved minerals in hard water. If your humidity and watering are fine but new brown tips keep appearing, your water is a strong suspect. The same thing happens with other fussy plants, as explained in our guide to calathea leaves curling.
How to fix it:
Spider plants need very little feeding. Too much fertilizer, or feeding through the winter when the plant is barely growing, leaves salts in the soil. You may see a white or yellowish crust on the soil surface or around the rim of the pot. These salts burn the leaf tips.
How to fix it:
If the soil also grows white fuzz after flushing, see how to deal with white fungus on plant soil.
Spider plants store water in thick, fleshy roots, so they forgive a missed watering. But if the soil goes completely dry again and again, the plant protects itself by letting the tips die. You will usually see crispy tips together with leaves that look pale, limp or folded.
How to fix it: water when the top 1 inch (2.5 cm) of soil feels dry. Water slowly until it runs out of the drainage holes, then empty the saucer. Check with your finger rather than watering on a fixed schedule.
Too much water causes brown tips too, but they look different: darker brown or almost black, often with yellowing leaves and soil that stays wet for days. Soggy soil also attracts tiny flies; if you see them, read how to get rid of fungus gnats in houseplants.
How to fix it:
Spider plants grow best in bright, indirect light at about 60–80°F (15–27°C). In winter, leaves pressed against a cold window or sitting next to a drafty door can be damaged where they touch. Temperatures below about 50°F (10°C) can harm them. In summer, hot direct sun through glass can scorch leaves instead.
How to fix it: keep the plant close to a bright window but not touching the glass, and away from outside doors and AC vents. In summer, pull it back from a hot south- or west-facing window or filter the light with a sheer curtain.
Spider plants grow fast and fill their pots with thick white roots. Once the pot is packed, there is very little soil left to hold water, so it runs straight through and the plant dries out quickly, which shows up as brown tips. Roots growing out of the drainage holes or pushing the plant up out of the pot are clear signs.
How to fix it: repot in spring into a pot only 1–2 inches (2–5 cm) wider, with drainage holes and fresh all-purpose potting mix. Most spider plants need this every one to two years.
Repot if roots fill the pot, water runs straight through, or you found root rot. Spider plants are very hard to kill: even if most of the leaves are brown, a plant with firm white roots or a healthy center will usually grow back. If the whole root ball is mushy and the center of the plant pulls away easily, the mother plant is unlikely to recover. In that case, cut off any healthy baby plantlets (spiderettes), root them in water or moist potting mix, and start again. For other emergency steps, see how to save a dying plant.
Yes. Spider plants are listed as non-toxic to cats and dogs by the ASPCA. Cats do love to chew the leaves, and eating a lot can cause a mild upset stomach, so hang the plant or put it on a high shelf if your cat treats it as a snack. Chewed tips can turn brown too, so check for bite marks.
If the brown areas are spreading as spots or rings rather than staying at the tips, or you see webbing or tiny insects, it may be a pest or a leaf disease rather than a care issue. Take a clear photo of the leaves and upload it to our free AI plant diagnosis for a likely cause and treatment. Not 100% sure your plant is a spider plant? Use the plant identifier first.
Yes, if you don't like the look. Trimming does not harm the plant. Use clean, sharp scissors, cut at an angle that copies the natural pointed tip, and leave a thin sliver of brown so you don't cut into healthy tissue.
No. The brown part is dead tissue and will not recover. The goal is to fix the cause so new leaves stay green, then trim the old tips for looks.
Not always, but spider plants are sensitive to fluoride, chlorine and hard-water minerals. If brown tips keep appearing even with good watering and humidity, switch to rainwater, distilled water or a filter that removes fluoride.
There is no fixed schedule. Water when the top 1 inch (2.5 cm) of soil is dry, which may be every 1–2 weeks in a cool room and more often near a heater. Always let extra water drain away.
Brown tips with yellowing leaves and wet soil usually mean overwatering or root rot. Let the soil dry out and check the roots. Our guide to yellow leaves on indoor plants covers the other causes.
