What Is Chlorosis?
Chlorosis is a condition that affects trees and plants, causing their leaves to turn yellow while the veins remain green. This discoloration is often a sign that the plant cannot produce enough chlorophyll, the pigment responsible for its green color and essential for photosynthesis. Chlorosis can weaken trees and reduce their vitality, making timely management crucial.
What Causes Chlorosis?
Chlorosis can result from several underlying issues, including:
Nutrient Deficiencies: A lack of essential nutrients like iron, manganese, or zinc can prevent the tree from producing enough chlorophyll.
Poor Soil Conditions: Compacted soil, improper pH levels, or inadequate drainage can interfere with nutrient absorption.
Root Damage: Injuries to the roots from construction, pests, or disease can restrict nutrient uptake.
Overwatering or Drought: Both excess water and insufficient moisture can contribute to chlorosis by affecting root function.
Is Chlorosis Harmful to Trees?
Yes, if left untreated, chlorosis can significantly weaken trees. A lack of chlorophyll limits photosynthesis, reducing the tree’s ability to produce energy. Over time, this can lead to poor growth, increased vulnerability to pests and diseases, and even tree death.
How is Chlorosis Treated?
Effective treatment starts with identifying and addressing the underlying cause. Here are some common solutions:

1. Soil Testing: Conduct a soil analysis to determine nutrient deficiencies or pH imbalances.
2. Nutrient Supplements: Apply fertilizers or chelated iron products to restore essential nutrients.
3. Adjust Soil pH: If the soil is too alkaline, adding sulfur or organic matter can help lower the pH to an optimal range.
4. Improve Drainage: Aerate compacted soil or install drainage systems to prevent waterlogging.
5. Proper Watering Practices: Ensure the tree receives water without overwatering.
6. Prune and Mulch: Remove damaged branches and apply mulch to retain soil moisture and regulate temperature.
