Why Are My Plant Leaves Turning Brown?

The natural color of a photosynthetic plant is green. Photosynthetic plants are plants that derive nutrition from the sun through the chlorophyll pigment contained in their leaves. So, apart from plants that produce their own food (which is rare), the leaves of plants are green.

An evenly green leaf is a sign of a leaf filled with chlorophyll, and that means it is a healthy plant. However, in autumn or fall, the leaves of plants naturally change from green to a variety of colors, such as red, yellow, orange, or purple. This is due to the change in weather conditions and the fact that plants stop making food during this time.



This tells you that it is natural for the leaves of a plant to change color in autumn. However, if your plant’s leaves suddenly start turning brown, it is not normal and requires attention.

Below are the reasons for the browning of leaves. 

Aging of plants

Some houseplants have leaves that turn brown as they mature. One such plant is the fern. All you have to do in this case is carefully prune the brown leaves, then remove the leaves that have fallen, and you are good to go.


This means the process a plant undergoes to adjust to a change in the environment. When a plant’s environment is changed, the plant goes through a series of processes while trying to adjust to the new environment. One of them is browning its leaves.

The wrong quantity of resources

The leaves of a plant tend to become brown when the plant is not getting the optimal amount of resources. For instance, if it is getting

  1. Not Enough Water;
  2. Hard water;
  3. Too much water (Overwatering);
  4. Improper watering;
  5. Low humidity;
  6. Lack of light;
  7. Too much fertilizer;
  8. Air that’s too dry; or
  9. Too many sun rays.


The only way to prevent your plant from turning brown is to ensure they get the exact amount of resources they need.
