1、How To Grow Lychee Trees With The Right Fertilizer

Supplement with Other Nutrients: Lychee trees need other nutrients, such as magnesium, calcium, and sulfur, in addition to nitrogen, phosphorus, and potassium. Look for a fertilizer that contains these additional nutrients, or consider supplementing with an additional fertilizer or soil amendment.

2、Guide to Fertilizing Your Lychee Plant

Like other fruit-bearing trees, lychee plants require a balanced supply of macronutrients (nitrogen, phosphorus, and potassium) as well as micronutrients (iron, manganese, zinc, etc.) for healthy growth and fruit production.

3、Best Fertilizer for Lychee Tree: Homemade, Organic, Liquid, NPK, and

Calcium levels are not essential to apply in soils with high calcium content, but in soils where pH ranges between 5.5 and 6.5, calcium may be required to be added in the form of dolomite lime.

4、When To Fertilize Lychee Tree? (And 7 Signs Your Lychee Tree Needs One)

It’s tempting to think more is better, but too much fertilizer can burn the roots of your lychee tree. This stress can stunt growth, damage foliage, or even kill the lychee tree.

What Is The Best Fertilizer For Lychee Tree? Secrets Revealed

Both organic and inorganic fertilizers can be effective for lychee trees. Organic fertilizers, such as compost and manure, provide a slow and sustained release of nutrients, while inorganic fertilizers offer a quick and concentrated source of nutrients.

FERTILISING LYCHEES

The question of Lychee nutrition is not set in concrete but there are now more areas of agreement than disagreement between people who have studied the fruit. It is hoped that the above may give some guidelines on which to base a fertiliser program.

Should I Fertilize My Lychee Tree?

Which fertilizer is best for lychee tree? Fertilizer mixtures containing 6 to 8% nitrogen, 2 to 4% available phosphorus, 6 to 8% potash, and 3 to 4% magnesium are satisfactory.

How to Fertilize Lychee Trees for Optimal Growth?

A balanced fertilizer with equal parts nitrogen, phosphorus, and potassium (such as a 6-6-6 NPK) is ideal for Lychee trees. This blend supports overall growth and optimizes fruit production.

What Kind Of Fertilizer Is Use For Lychee Tree

Newly planted lychee trees require minimal fertilizer for their first year, with regular watering. Once established, feed them quarterly with an organic fruit tree fertilizer from late winter to summer.

Am I Starving My Lychee? Fertilizing 101

Heavy rains can spell disaster for a freshly fertilized lychee tree, washing away nutrients and potentially harming the roots. In such cases, a time-release fertilizer can be your best friend, releasing nutrients only when needed.

Lychee, also known as Dan Li or Yu Li, is a tropical fruit cherished for its plump flesh, vibrant color, and sweet flavor. In lychee cultivation, fertilization is a critical practice to enhance yield and fruit quality. Calcium fertilizer, as a key nutrient source, plays a vital role in lychee growth and development. This article explores whether lychee requires calcium fertilizer and its specific functions.

1. Lychee’s Requirement for Calcium Fertilizer

(1) Promoting Root Development

Calcium fertilizer improves soil structure and increases calcium availability, boosting the root system’s ability to absorb water and nutrients. A healthy root system is essential for lychee growth, as it ensures efficient uptake of soil nutrients, providing adequate nourishment for normal development.

(2) Enhancing Stress Resistance

Calcium strengthens the plant’s disease resistance and adaptability to adverse conditions. During growth, lychee may face pests, diseases, drought, or temperature extremes. Calcium fertilization reduces pest-related losses by improving disease resistance and enhances tolerance to drought, frost, and other stresses, ensuring stable growth under challenging conditions.

(3) Improving Fruit Quality

Calcium directly impacts fruit quality. As a critical nutrient, calcium promotes sugar accumulation, increasing sweetness. It also supports the synthesis of proteins, fats, and other compounds, elevating the overall nutritional value and market appeal of lychee fruits.

2. Methods and Precautions for Applying Calcium Fertilizer

(1) Selecting Appropriate Calcium Sources

Common calcium fertilizers include lime, gypsum, and calcium phosphate. Lime is rich in calcium but excessive use may raise soil pH, affecting nutrient balance. Gypsum provides sulfur, benefiting soil microbial activity. The choice depends on soil type and lychee needs.

(2) Rational Application

• Dosage: Apply 10–20 kg of lime or gypsum per mu (approx. 0.067 hectares), adjusted based on soil tests and growth stages.
• Frequency: Avoid overapplication to prevent calcium toxicity, which disrupts nutrient absorption.
• Method: Use trench or hole application to avoid direct root contact and potential burning.

(3) Combining with Other Fertilizers

For optimal results:

• Pair calcium with phosphorus fertilizers to enhance phosphorus uptake.
• Combine with potassium to improve stress resistance.
• Add microelements like boron or zinc to support overall tree health.

Lychee cultivation indeed benefits from calcium fertilizer. Proper use strengthens roots, boosts resilience, and improves fruit quality. Farmers should tailor calcium application to soil conditions and growth phases, avoiding excess or deficiency. With scientific fertilization, lychee productivity and profitability can be significantly enhanced.
