Common Causes of Brown Leaves on Coffee Plants
There can be a multitude of reasons behind the browning of coffee plant leaves. Below are some common culprits.
1. Overwatering
Overwatering is one of the leading causes of brown leaves in coffee plants. The roots need oxygen to thrive, and overly damp soil can suffocate them. When this happens, the plants develop root rot, which often manifests through browning leaves.
Symptoms of Overwatering
- Soil remains soggy for extended periods
- A musty smell from the soil
- Leaves might appear wilting or yellowing before turning brown
Solution
To combat overwatering, ensure that your coffee plant is in well-draining soil. Allow the top inch of soil to dry out before watering again. Consider using pots with drainage holes to prevent water collection.
2. Underwatering
Just as overwatering can be detrimental, underwatering presents its own set of challenges. Coffee plants prefer environments that retain moisture while yet providing a good drainage system.
Symptoms of Underwatering
- Soil appears dry and crusty
- Leaves start to curl and become brittle
- Brown tips develop, and eventually the leaves might fall off
Solution
Ensure that you are providing consistent watering—wetting the soil and allowing it to dry slightly between waterings. Observe your plant closely to establish a routine that meets its needs.
3. Insufficient Humidity
Coffee plants originate from tropical regions, which means they thrive in environments with high humidity. When the air in your home is too dry, particularly in winter, it can cause the leaf tips to brown.
Symptoms of Low Humidity
- Crisp brown leaf tips or edges
- Leaves may curl downwards
- Overall stunted growth
Solution
To increase humidity around your coffee plant, consider the following methods:
- Utilize a humidifier in the room where your plant resides.
- Place a tray filled with water and pebbles beneath the plant to encourage evaporation.

What causes the leaves of my coffee plant to turn brown?
The browning of coffee plant leaves can be attributed to several factors including environmental stress, pests, or diseases. One common reason is improper watering; either too much or too little can cause the leaves to brown. Overwatering can lead to root rot, reducing the plant’s ability to absorb nutrients. Conversely, under-watering can cause dehydration, putting stress on the leaves.
Another factor to consider is light exposure. Coffee plants thrive in bright, indirect sunlight. If they are exposed to direct sunlight for extended periods, the leaves may scorch, leading to browning. Additionally, fungal infections or infestations from pests such as spider mites can also cause leaf discoloration. Identifying the specific cause is crucial for effective treatment.
How can I determine if my coffee plant is overwatered or underwatered?
To determine if your coffee plant is overwatered, check the soil’s moisture level. If the top inch of soil feels consistently wet and the leaves show signs of yellowing or browning, your plant may be getting too much water. You can also inspect the roots by gently lifting the plant from its pot. If the roots appear dark and mushy, it’s a clear sign of overwatering.
On the other hand, if the soil feels dry several inches below the surface and the leaves are curling or turning crispy at the edges, the plant is likely underwatered. A healthy coffee plant should have soil that is moist but well-draining. Monitoring the moisture levels regularly and adjusting your watering routine based on the plant’s needs will help maintain its health.
What should I do if I find pests on my coffee plant?
If you discover pests on your coffee plant, the first step is to isolate the affected plant to prevent the pests from spreading to other plants.
