4 Tips for Fertilizing Your Litchi

For post-bloom, fertilize 2-4 weeks after flowering to support fruit set and ensure a bountiful harvest. With these timing tips, your litchi tree will be well-prepared to flourish through each growth stage. Next, let’s explore how to effectively fertilize your tree for optimal results.

Best NPK fertilizer for litchi

Conservation fertilizer usually refers to a fertilizer applied after the litchi is picked, which can effectively prevent the premature aging of fruit trees, thereby increasing the yield of litchi.

Effect of Foliar Feeding with Nutrients and Bioregulators on Yield and

The highest total fruit yield was recorded in plants subjected to foliar feeding with 0.3% Borax (T2) which was found to be statistically similar to plants treated with 0.1% seaweed extract (T10) and 0.5% seaweed extract (T9).

Effect of Foliar Spray of Chemicals on Flowering and Fruiting in Litchi

In this investigation, it is indicated that, foliar spray of different forms of potassium and ethrel improved flowering and final fruit yield in litchi trees. Bihar is known as hub of litchi production not only in India but also in the world due to its quality fruit.

The foliar fertilization showed an increasing trend towards plant height (12.17% with 0.03% Zn two weeks after fruit set), fruit weight (150g with 0.03% B two weeks after fruit...

Applying foliar fertilizers after litchi fruit set is a critical measure to enhance fruit quality and yield. During this stage, foliar spraying effectively promotes fruit growth, improves quality, increases production, and boosts the tree’s disease resistance. Below are key recommendations for optimizing foliar fertilization in litchi after fruit set:

1. Select Appropriate Fertilizers: Choose formulations tailored to litchi’s growth stage and nutritional needs. After fruit set, opt for foliar fertilizers rich in nitrogen (N), phosphorus (P), potassium (K), and microelements, such as urea, potassium dihydrogen phosphate, and magnesium sulfate. These provide essential nutrients to support fruit development.

2. Application Method:

   • Apply on sunny days, avoiding rainy or extremely hot weather.
   • Clean leaves before spraying to ensure optimal absorption.
   • Spray uniformly across leaves, targeting 5–10 kg of solution per hectare. Ensure full coverage without missed spots.

3. Timing: The ideal window is 10–15 days after flowering, when fruits enter rapid expansion. Timely nutrition supplementation during this phase prevents developmental issues and ensures high-quality yields.

4. Concentration: Adjust concentrations based on the fertilizer type:

   • Urea: 0.5–1% solution.
   • Potassium dihydrogen phosphate: 0.2–0.3% solution.
   • Magnesium sulfate: 0.1–0.2% solution. Excessive concentrations may scorch leaves, while diluted solutions risk ineffective results.

5. Frequency: Apply every 7–10 days post-fruit set. For nutrient-poor soils, increase frequency to meet the trees’ demands.

6. Precautions:

   • Avoid direct spraying on fruits to prevent quality damage.
   • Do not apply during heatwaves (risk of leaf burn) or rain (fertilizer wash-off).

Foliar fertilization after litchi fruit set is vital for maximizing yield and quality. By selecting suitable fertilizers, following proper application techniques, and adhering to timing and dosage guidelines, growers can ensure robust nutrient supply, accelerate fruit expansion, and enhance marketability. Always avoid over-fertilization, which may hinder growth.
