Why Are My Plant’s Leaves Turning Brown?
Brown Leaf Tips - What’s Actually Causing Them?
Brown, crispy leaves are incredibly common on houseplants. That doesn’t mean we like them, though!
So, what do you do if your plants are starting to turn brown at the edges? First of all, don’t panic. A little browning doesn’t mean something is seriously wrong, but it likely means your plant is under some kind of stress. The trick is figuring out what kind of stress they’re experiencing. There are a few main culprits when it comes to brown tips.
Not Enough Water
One of the most common reasons your plant is getting crispy tips is because it isn’t getting enough water. This is especially true for plants that like consistently moist soil, like ferns, calathea, and alocasia. If the soil is dry and pulling away from the edge of the pot, consistent under-watering may be the culprit.

Too Much Water
I know, I know. I just said it could be not enough water, but surprisingly, too much water can also cause brown tips on your leaves! Constantly wet soil can damage roots, which means that the leaves cannot take up water properly, leading to brown tips. Often, you will have other signs too, like yellowing leaves, mushy stems, or soggy soil. To help prevent this, make sure your pot has proper drainage and that you are checking the soil before watering.
Because, of course, plants have decided that both too much water AND too little water can make them unhappy. Very helpful.
Low Humidity
At least in Southern Oregon, low humidity is a constant battle we are fighting when we have houseplants that are native to the tropics. If you know your watering and lighting are on point, there is a chance your brown tips are coming from the air being too dry. This is especially noticeable when heaters are running. Consider adding a humidifier or grouping plants together to help increase their humidity.
Too Much Sun
Strong, direct sunlight can cause leaf edges to burn. If your leaves are only browning where they are closest to the sun, that’s a good indicator that it is too bright for your plant. Remember that most plants prefer bright, indirect light. This is very different from direct afternoon sun!
Fertilizer or Mineral Buildup
Over-fertilizing can cause brown, crispy leaves as well. This is why we recommend slowing down with fertilizer during the winter months. Also, make sure that you are following the directions provided. Minerals from tap water can also build up over time and cause similar damage to your plant. If you suspect one of these issues, a repot is probably in order.
Temperature and Environmental Stress
Sudden changes in temperature or environment can also cause brown tips. Cold drafts, hot air from heaters, or being too close to an AC vent can all affect your plants. Consider what is happening around your plant to help diagnose the problem.
So…what should I do?
Brown + crispy? → Check watering and humidity.
Brown + yellowing? → Check for overwatering/root issues.
Brown on the side facing the window? → Check for sunburn.
Brown tips after fertilizing? → Consider fertilizer or mineral buildup.
Sudden browning after a temperature change? → Check for environmental stress.
Brown leaves are your plant’s way of saying, “Something is wrong over here.” The goal is to look at the whole picture—watering, light, humidity, temperature, soil, and fertilizer—to figure out what your plant is trying to tell you. And remember: a few brown tips are not a plant-care failure. Sometimes your plant is just being a little dramatic.
An important note is that even after you solve the problem, those tips are never turning green again. If you prefer, you can trim off the damaged portions, but it isn’t necessary. The most important thing you can do is to fix the root cause rather than just cutting off the evidence.
