Spider plant brown tips are a common issue that frustrate both beginner and seasoned plant lovers. You might have a thriving spider plant with arching green leaves and those charming baby “spiderettes”—yet the edges of the leaves are turning dry, crispy, and brown. What gives?
According to Justin Hancock, a horticulturist at Costa Farms, brown tips are typically a signal that something in the plant’s environment is out of balance. Whether it’s dry soil, low humidity, or even a sneaky draft, these stressors can all show up as browning leaf tips.
The good news? Most causes of brown tips are easy to fix with a few simple adjustments to your plant care routine. Let’s break down the most likely culprits and how to get your spider plant looking lush and healthy again.

Your Plant Has Gotten Too Dry
One of the most common reasons for spider plant brown tips is underwatering. When a spider plant’s soil gets too dry, especially for prolonged periods, the plant struggles to absorb the moisture it needs to support healthy leaf growth. The result? Crispy, brown tips that won’t go away on their own.
Spider plants prefer consistently moist—not soggy—soil. A good rule of thumb is to water when the top 1 to 2 inches of soil feel dry to the touch. Avoid letting the soil dry out completely between waterings, as this can stress the plant and damage its delicate roots.
“Rather than sticking to a strict schedule, observe your plant’s needs,” says Justin Hancock. “You’ll often find a rhythm by checking the soil weekly and adjusting based on humidity, light, and temperature.”
Tips to Prevent Underwatering:
- Use your finger to check soil moisture weekly.
- Water thoroughly until water drains from the bottom of the pot.
- Use a potting mix that retains some moisture but drains well.
- Adjust watering frequency during hot or dry weather.
If your spider plant has already developed brown tips from dryness, trimming them won’t hurt the plant—but prevention is the key to keeping new tips from turning brown.
Your Plant Is Exposed to Drafts
Another often-overlooked reason for spider plant brown tips is exposure to drafts. Spider plants are sensitive to sudden changes in temperature or constant airflow—especially from heating vents, air conditioners, or drafty windows.
Cold or hot drafts can dry out the leaf edges, leading to that classic browning effect. Even if you’re watering correctly, a plant sitting too close to a vent or window that leaks air can still struggle.
“When diagnosing brown tips, I always check if the plant is sitting near a draft,” says Hancock. “Relocating it to a more stable environment can make a big difference.”
How to Protect Your Spider Plant from Drafts:
- Keep your plant away from direct airflow sources (vents, fans, open windows).
- Avoid placing it near exterior doors or drafty corners.
- If your home has central heating or air conditioning, monitor temperature shifts near your plant’s location.
- Consider using a thermometer to ensure the temperature stays in the 65–75°F (18–24°C) range.
Once a leaf tip has browned due to draft damage, it won’t turn green again. However, removing the source of the stress will prevent new tips from browning in the future.
Humidity Levels Are Low
Low humidity is another key culprit behind spider plant brown tips. Native to tropical and subtropical regions, spider plants naturally thrive in environments with humidity levels around 50–60%. When indoor air is too dry—especially in winter or in homes with central heating—the leaf tips can quickly turn brown and brittle.
Dry air pulls moisture from the plant’s leaves faster than the roots can replace it, leading to dehydration at the edges. This is especially noticeable if the brown tips appear even though your watering routine is on point.
Easy Ways to Boost Humidity:
- Mist your plant lightly every few days (but avoid misting too much, which can lead to fungal issues).
- Group plants together—they release moisture through transpiration and benefit from shared humidity.
- Place the pot on a pebble tray filled with water (keep the pot above the waterline).
- Use a room humidifier, especially during dry winter months.
- Relocate to a naturally humid room, like the bathroom or kitchen.
Avoid placing your spider plant near heating vents or radiators, which dry the air even further. Consistent humidity is one of the best defenses against those pesky brown tips.
You’ve Overfertilized Your Plant
Overfertilization is another sneaky reason for spider plant brown tips, especially if you’ve been generously feeding your plant in hopes of boosting growth. While spider plants do appreciate nutrients, too much fertilizer—particularly chemical salts—can accumulate in the soil and damage the roots. This stress often shows up first as brown leaf tips.
You might also notice a white, crusty buildup on the surface of the soil. That’s a telltale sign of salt accumulation, and it means your plant’s root system is likely overwhelmed.
Smart Fertilizing Tips:
- Fertilize only during active growth seasons—typically spring and summer.
- Use a diluted, all-purpose liquid fertilizer once a month.
- Avoid feeding your plant during fall and winter when growth slows.
- Always follow the fertilizer label’s instructions—less is more with spider plants.
If you suspect overfertilization, pause feeding immediately. Giving your plant time to recover and flushing the soil (which we’ll cover next) can help restore balance and stop further browning.
Fix by Flushing the Soil
If overfertilization is contributing to spider plant brown tips, the most effective remedy is flushing the soil. This simple process washes away built-up salts and minerals that may be stressing your plant’s roots and burning the leaf tips.
Over time, fertilizer salts and minerals from tap water accumulate in the soil, especially if you’re using a non-draining container or rarely repotting. Flushing gives your plant a clean slate—literally.
How to Flush Your Spider Plant’s Soil:
- Place the plant in the sink or tub.
- Slowly pour room-temperature water through the soil until it drains freely from the bottom.
- Continue watering gently for a few minutes—use about 3–4 times the pot’s volume in water.
- Allow the plant to drain completely before returning it to its usual spot.
You may need to repeat this every few months, especially if you fertilize regularly. Also, if you notice a white crust on the soil or brown tips that persist despite correct watering, flushing is your best first step.
After flushing, give your spider plant a break from fertilizer for at least a month to let the roots recover.
FAQ
Should I Cut Off the Brown Tips?
Yes, you can safely trim brown tips without harming the plant. Use clean, sharp scissors and snip just the browned portion of the leaf—avoid cutting into the healthy green tissue. While trimming is purely cosmetic (it won’t make the leaf turn green again), it keeps your plant looking neat and tidy.
What Are the Signs of Overwatering?
An overwatered spider plant may show several symptoms beyond just spider plant brown tips, including:
- Pale or yellowing leaves
- Mushy or soft stems
- Drooping or curling leaves
- Persistent soil dampness
- Fungus gnats hovering near the soil
Let the soil dry out between waterings and ensure your pot has proper drainage to avoid root rot.
How Often Should I Water My Spider Plant?
Water your spider plant when the top 1–2 inches of soil feel dry. For most indoor environments, this typically means watering once every 7–10 days. However, frequency can vary based on:
- Indoor temperature
- Humidity levels
- Pot size and material
- Light exposure
Always feel the soil before watering—avoid sticking to a strict schedule.
How Much Light Does a Spider Plant Need?
Spider plants thrive in bright, indirect light. They should get at least 8 hours of filtered sunlight per day. Morning sun is ideal, but avoid harsh afternoon rays which can scorch the leaves and worsen browning.
If your plant isn’t getting enough light, it may become leggy, limp, or dull in color. Conversely, too much direct sun can cause more brown tips and dry patches.
Conclusion
Spider plant brown tips are a common, yet manageable issue. Whether it’s due to underwatering, exposure to drafts, low humidity, or overfertilization, your spider plant is simply signaling that something needs adjusting. By paying attention to your plant’s environment and care routine—and using tricks like soil flushing and humidity boosting—you can restore your spider plant’s vibrant, healthy appearance.
With the right balance of water, light, nutrients, and air quality, those lush green leaves will thrive without the telltale brown edges. And remember, trimming brown tips is perfectly safe—just keep an eye on what your plant is telling you for future prevention.
