Why Do Indoor Plant Leaves Turn Brown?

Brown leaves on indoor plants can be caused by a variety of factors, including:

Overwatering: Too much water can cause roots to rot, leading to a decrease in oxygen and nutrients, which can cause leaves to turn brown.

Underwatering: On the other hand, not enough water can also cause leaves to turn brown, especially if the plant is exposed to dry air or high temperatures.

Nutrient Deficiency: Lack of essential nutrients like nitrogen, iron, or magnesium can cause leaves to turn brown or yellow.

Air Pollution: Indoor air pollution can cause leaves to turn brown, especially if the plant is exposed to chemicals or pollutants.

Lighting Issues: Too little or too much light can cause leaves to turn brown, especially if the plant is not adapted to the lighting conditions.

How to Identify the Cause of Brown Leaves

To identify the cause of brown leaves, it's essential to observe your plant closely and look for other signs of stress or disease. Here are some tips to help you identify the cause:

Check the soil moisture: Stick your finger into the soil up to the first knuckle. If the soil feels dry, it may be underwatered. If it's waterlogged, it may be overwatered.

Inspect the leaves: Look for signs of pests, diseases, or nutrient deficiencies. Check for tiny eggs, webs, or actual pests on the leaves.

Check the temperature: Make sure the temperature is within the recommended range for your plant species.

Check the lighting: Ensure the plant is receiving the right amount of light. If it's too low, consider moving it to a brighter location.
