Agave Pest Control & Common Causes of Dying Plants

Agave are tough and easy-to-grow plants, but improper management or environmental changes can lead to problems. With many high-value rare varieties, early detection and appropriate treatment are especially important.

Common Diseases and Problems

Root Rot - **Symptoms**: Base becomes soft and darkens with a rotting smell - **Cause**: Overwatering, poorly draining soil, winter overwatering - **Treatment**: Remove all rotted roots, apply fungicide to cuts, let dry, then repot in well-draining soil

Leaf Burn - **Symptoms**: White to brown discolored patches appear on leaf centers or tips - **Cause**: Sudden exposure to strong direct sunlight. Common when moving from indoors to outdoors - **Treatment**: Use shade cloth (30-50%) and gradually acclimate to sunlight

Scale Insects - **Symptoms**: Brown or white hard granules attached to leaf surfaces - **Cause**: Poor air circulation - **Treatment**: Physically remove with a toothbrush and apply insecticide

Mealybugs - **Symptoms**: White powdery or cotton-like clusters at leaf bases. Some species infest roots - **Cause**: Hot, dry conditions with poor ventilation - **Treatment**: Remove with alcohol-soaked cotton swabs and apply insecticide. For root infestations, wash off and repot

Frost Damage - **Symptoms**: Leaves become water-soaked and transparent, then darken and rot - **Cause**: Temperatures below the variety's cold tolerance, frost exposure - **Treatment**: Remove frost-damaged portions and treat with fungicide. Recovery is difficult if fully frozen

Prevention Tips

Water only "several days after soil is completely dry," and reduce to minimal or no watering in winter. When moving outdoors, gradually acclimate to sunlight over 1-2 weeks.
