The Guiana Chestnut, commonly known as the Money Tree, is a tropical wetland tree native to Central and South America. It thrives in humid environments with indirect sunlight. Yellowing leaves often indicate stress, which can stem from several factors, including water, light, nutrients, or pests. Identifying the root cause is essential for effective treatment.
Several factors can lead to yellow leaves on a Guiana Chestnut:
Water the Guiana Chestnut only when the top 1-2 inches of soil are dry. Ensure the pot has drainage holes to prevent waterlogging. If root rot is suspected, repot the plant in fresh, well-draining soil and trim any blackened roots.
Place the plant in bright, indirect light. Avoid prolonged exposure to direct sun, which can scorch leaves. If natural light is insufficient, consider using a grow light to supplement.
Use a balanced, water-soluble fertilizer every 4-6 weeks during the growing season. For iron or magnesium deficiencies, apply a chelated iron supplement or Epsom salts (magnesium sulfate) diluted in water.
Check the undersides of leaves for pests like spider mites or aphids. Treat infestations with insecticidal soap or neem oil. For fungal issues, improve air circulation and avoid wetting foliage when watering.
To prevent future yellowing:
Guiana Chestnuts may naturally shed older leaves during seasonal transitions. However, sudden or widespread yellowing outside of autumn likely indicates a problem. Adjust care routines seasonally—reduce watering in winter and increase fertilization in spring and summer.
