Overwatering
On the other hand, overwatering can also cause corn plant leaves to turn brown. When the roots are consistently soaked in water, they may become waterlogged and struggle to absorb oxygen properly. As a result, the leaves may develop brown spots or turn completely brown. To prevent overwatering, ensure that the plant’s container has proper drainage and only water when the top inch of the soil feels dry.
Improper Light Conditions
Improper light conditions can also contribute to corn plant leaves turning brown. These plants prefer bright, indirect light, but can tolerate lower light levels.

Similarly, if the plant is kept in a dark area with insufficient light, the leaves may also darken. Place your corn plant in a location that receives bright, filtered light to ensure its healthy growth.
Temperature Extremes
Extreme temperatures can cause stress to corn plants and lead to browning leaves. Cold drafts and temperatures below 50°F (10°C) can result in leaf discoloration. On the other hand, excessive warmth, such as being placed near a heat source, can also cause the leaves to brown. Maintain a temperature between 60-75°F (15-24°C) to keep your corn plant thriving.
Nutrient Deficiencies
Nutrient deficiencies can manifest through brown leaves on corn plants. Lack of essential nutrients like nitrogen, potassium, and magnesium can cause leaf discoloration.

Checking The Soil
The condition of the soil can provide valuable insights into the health of your corn plant. Start by ensuring the container or planting area has proper drainage. Stagnant water can lead to root rot, causing the leaves to turn brown. Check the moisture level of the soil:

Examining Environmental Factors
Environmental factors can significantly impact the health of your corn plant. Consider the following aspects:
- Lighting: Is the corn plant getting sufficient natural or artificial light? Inadequate light can cause brown leaves.
- Temperature: Extreme heat or cold can stress the plant and lead to browning.
- Humidity: Corn plants prefer a moderate level of humidity. Low humidity can result in dry leaves.
- Air Circulation: Poor air circulation can contribute to leaf discoloration.
Assess these environmental factors and make any necessary adjustments to create an optimal growing environment for your corn plant.
