Iron deficiency is a common problem in many plants, leading to yellowing leaves and stunted growth. Foliar feeding offers a quick and effective way to supply iron directly to the plant’s leaves. This method can be especially useful when soil conditions prevent iron absorption.
Understanding Iron Deficiency in Plants
Iron is essential for chlorophyll production and overall plant health. Deficiency symptoms include:
- Yellowing between leaf veins
- New leaves turning yellow first
- Stunted growth
When to Use Foliar Feeding
Foliar feeding is most effective when:
- Plants show early signs of deficiency
- Soil conditions limit iron availability
- Rapid correction is needed
Preparing Iron Solutions for Foliar Feeding
Use chelated iron or iron sulfate for foliar sprays. Mix according to instructions, typically:
- Dissolve 2-3 teaspoons of chelated iron in a gallon of water
- Ensure thorough mixing
Applying the Foliar Spray
Follow these steps for effective application:
- Spray early in the morning or late in the afternoon to avoid leaf burn
- Cover both sides of the leaves evenly
- Use a fine mist spray for uniform coverage
- Repeat every 7-10 days as needed
Precautions and Tips
To ensure safety and effectiveness:
- Test the spray on a small area first
- Avoid spraying during hot, sunny days
- Use protective gear if necessary
- Maintain proper dilution to prevent leaf damage
Conclusion
Foliar feeding is a practical solution for correcting iron deficiency quickly. When combined with proper soil management, it helps restore healthy, green foliage and promotes vigorous growth.
