How to Fix Tangerine Tree Leaf Curl

Fixing Nutrient Deficiencies in Tangerine Trees

Nutrient deficiencies are one of the main causes of leaf curl in tangerine trees. When your tree isn’t getting the right balance of nutrients, it will show signs such as yellowing leaves, poor fruit production, and distorted growth. Here’s a guide on how to fix nutrient deficiencies and keep your tangerine tree healthy:

Common Nutrient Deficiencies in Tangerine Trees

Each nutrient plays a specific role in the tree’s health. If any of these are deficient, the tree will struggle to grow and fruit effectively:

• Nitrogen (N) Deficiency: Nitrogen is essential for healthy leaf and stem growth. If there’s not enough nitrogen, older leaves will turn yellow, and the tree will produce less fruit. Solution: Apply a balanced fertiliser like CompleteGrow Citrus Fertiliser, which is rich in nitrogen.
• Potassium (K) Deficiency: Potassium helps the tree develop strong fruit and improves resistance to disease. Low potassium results in smaller, less flavorful fruit and poor fruit retention. Solution: Use a potassium-rich fertiliser like CompleteGrow Citrus Fertiliser to provide the right amount of potassium.
• Magnesium (Mg) Deficiency: Magnesium is crucial for photosynthesis and overall health. Deficiency symptoms include interveinal chlorosis (yellowing between leaf veins). Solution: Add magnesium with a supplement like CompleteGrow CalMag.
• Iron Deficiency: Iron is necessary for chlorophyll production. Without it, young leaves turn yellow while veins remain green. Solution: Apply iron chelates or use a fertiliser designed to correct iron deficiencies.

How to Correct Nutrient Deficiencies in Tangerine Trees

To address nutrient deficiencies, you’ll need to adjust both your fertilisation practices and watering habits:

• Use the Right Fertiliser: Apply a complete fertiliser like CompleteGrow Citrus Fertiliser, which provides the correct balance of nitrogen, phosphorus, potassium, and trace elements for healthy tangerine trees.
• Adjust pH Levels: Ensure that your soil has a pH level between 5.5 and 6.5 for optimal nutrient uptake. If the pH is too high or too low, nutrients won’t be absorbed properly. Use soil amendments like sulfur to lower pH or lime to raise it.
• Monitor Regularly: Check your tree for signs of nutrient deficiencies and adjust your fertilisation schedule accordingly. Don’t wait for problems to get worse—early intervention can prevent long-term damage.
• Feed Regularly: Tangerine trees need consistent, balanced feeding during the growing season. Fertilise every 4–6 weeks during spring and summer with a liquid or soluble fertiliser, and reduce feeding during fall and winter.

With the right care and fertilisation schedule, your tangerine tree will thrive, producing healthy, vibrant fruit. Regular monitoring of nutrient levels and adjusting your care routine ensures long-term success.
