7 Reasons for Agave Leaves Turning Yellow

Agave plants are amazing, but sometimes their leaves can turn yellow, and it’s not a good sign. But don’t worry, we’re here to help you figure out why it’s happening and what you can do about it!

1. Overwatering

Giving your agave too much water can make its roots sick and cause the leaves to turn yellow. To fix this, make sure the soil is completely dry before watering again. Also, use a pot with good drainage so the extra water can escape.

2. Not Enough Nutrients

Agaves need special plant food to stay healthy. If they don’t get enough, their leaves might turn yellow. You can fix this by giving your agave fertilizer made for succulents. It’ll give them the nutrients they need.

3. Lack of Sunlight

Agaves love the sun, but if they don’t get enough light, their leaves might turn yellow. Make sure your agave gets at least 6 hours of indirect sunlight every day. If it’s inside, move it to a spot with more light. If it’s outside, find a sunny place for it.

4. Temperature and Humidity

Agaves don’t like the cold, and they need the right amount of humidity. If they’re too cold or too dry, their leaves can turn yellow. Keep your agave in a place where the temperature is not below 65°F (18°C). You can also use a humidifier to add moisture to the air if it’s too dry.

5. Moving Stress

Sometimes, when you move your agave from one place to another, it gets stressed and its leaves turn yellow. To avoid this, handle the plant gently when you move it and water it well after transplanting. Also, make sure the temperature and humidity are good while it adjusts to its new home.

6. Soil Type and pH

Agaves like a specific type of soil with the right acidity level. If the soil is not good, the leaves can turn yellow. Use well-draining soil that is slightly acidic, with a pH level between 6.0 and 7.5. You can add compost or peat moss to improve the soil if needed.

7. Pests and Diseases

Pesky bugs and diseases can also make your agave leaves yellow. Watch out for pests like aphids, mealybugs, and scale insects. If you see them, use insecticidal soap or neem oil to get rid of them. Powdery mildew and fungal leaf spots are common diseases that can cause yellow leaves too. Keep the foliage dry, improve airflow, and use fungicides to control the spread.

How to Revive a Dying Agave

If your agave plant is showing signs of distress, there are steps you can take to revive it. First, ensure the environment provides suitable conditions, such as consistent temperatures and adequate humidity. Check the pH of the soil and add compost or peat moss if needed.

Next, inspect the plant for pests and diseases. If you find any, use insecticidal soaps or neem oil to eliminate them. For fungal leaf spots or powdery mildew, apply fungicide or potassium bicarbonate spray.

In severe cases, consider propagating the agave by cutting off a healthy portion and replanting it. Use fresh, well-draining soil for the new plant to have a fresh start.

Should You Trim Damaged Agave Leaves?

Yes, it’s essential to trim damaged agave leaves. Damaged leaves can lead to rot and spread diseases to other parts of the plant. Promptly removing them will prevent further damage and disease transmission.

When trimming, use clean scissors or shears for precise cuts without harming the rest of the plant. Dispose of the removed leaves appropriately, like composting or removing them from your yard. These steps will help maintain the health and vibrancy of your agave plants.


Agave plants are generally easy to care for, but yellow leaves can still occur. Preventing yellowing leaves involves maintaining suitable environmental conditions, using well-draining soil, and being vigilant about pests and diseases.

If your agave is struggling, take steps to revive it by addressing environmental factors, treating pests and diseases, and considering propagation. Trimming damaged leaves is also crucial for the plant’s health. With proper care and attention, your agave will thrive, displaying beautiful, green leaves.
