Organic options promise a slow and steady nutrient release, nurturing soil health over time. Synthetic fertilizers offer a quick nutrient hit, potentially leading to rapid blooming. But beware, the latter can also lead to over-fertilization if not used with caution.

3、What Fertilizer to Use for Longan Tree? Choosing The Best

In this article, we will discuss the different types of fertilizers available, their benefits and drawbacks, and provide expert insights on how to choose the best fertilizer for your longan tree.

The latest course of fertilization techniques and methods for Young

Longan young tree management is mainly to promote branch growth and expand the crown, so in order to meet its growth needs, fertilizer must be fully applied, so how to apply fertilizer to longan young trees?

What is the best fertilizer for longan tree?

The longan tree requires equal ratio N:P:K fertilizer (i.e. 6:6:6 or 15:15:15, etc.). First year of planting: After one month of planting, fertilize with about 110 g (1/4 pound) of 5-5-5 NPK fertilizer every 2 months.

The Fertilizing Method of Longan bearing Tree

Spreading postharvest fertilizer for 5 ~ 10 days after longan fruit picking should give preference to instant and available nitrogen fertilizer and potash fertilizer, each of them should be applied with 0.75 ~ 1.00 kg urea and 0.50 ~ 0.75 kg potassium sulphate, with uniform broadcast on the topsoil under the canopy after the rain.

How To Put Fertilizer Into The Longan

Young longan trees require more consistent nutrition, while mature trees need around 1. 5 to 2. 25 kg (3. 3 - 5 lbs) of fertilizer before blooming and during harvest.

What Is Foliar Spray: Learn About Different Types Of Foliar Spraying

Usually water-soluble powder or liquid fertilizers are used. If you purchase a fertilizer, be sure that there are directions for foliar application. Foliar sprays are generally less concentrated than fertilizers that are placed on the soil.

For ground applications I use a combination of Gro-Power premium 8-6-8 Citrus and Avocado combined with controlled release Nutricote 18-6-8. I only recently started using the Nutricote but have seen excellent growth ever since I started. I like the Nutricote because I only need to apply once a year.

Application of plant growth regulators on fruit trees

When the main axis of the longan flower stalk is 5-6cm long, spraying 300-400 mg/L of cytokinin can promote the rapid development of the flower stalk and reduce the chance of shoot flushing.

Longan trees (Dimocarpus longan), also known as dragon eyes, are an important tropical fruit. In the cultivation of longan, rational fertilization is one of the key measures to improve yield and quality. Below is a detailed introduction to the methods, precautions, and recommended fertilizer types for foliar spraying on longan trees.

Importance of Foliar Fertilization for Longan Trees

Foliar fertilizers can be directly sprayed onto the leaves of longan trees. Once absorbed by the leaves, nutrients such as nitrogen (N), phosphorus (P), potassium (K), and trace elements like iron (Fe), zinc (Zn), and copper (Cu) are transported to various parts of the plant. This process rapidly replenishes essential nutrients, enhancing fruit quality and yield.

Steps for Foliar Fertilization on Longan Trees

1. Prepare Equipment: Use a sprayer or high-pressure water gun to ensure even distribution without damaging the plant.

2. Select Appropriate Fertilizers: Choose foliar fertilizers based on the growth stage of the tree and soil conditions. Common options include potassium dihydrogen phosphate, urea, and ammonium sulfate.

3. Dilute the Fertilizer: Mix the fertilizer with water according to the recommended ratio on the package (e.g., dilute 500-fold, adding 1-2 grams of fertilizer per liter of water).

4. Optimal Spraying Time: Conduct spraying in the morning or evening when temperatures are cooler and wind speeds are lower to minimize evaporation and improve nutrient absorption.

5. Spraying Method: Apply the diluted solution evenly onto the leaves, avoiding direct contact with the trunk or fruits to prevent scorching.

6. Precautions:

   • Avoid over-fertilizing, which may cause excessive growth or other issues.
   • Do not apply fertilizers during hot periods to prevent rapid evaporation.
   • Monitor the plant’s response and address abnormalities promptly.

Recommended Fertilizer Types and Application Methods

1. Potassium Dihydrogen Phosphate: Suitable for various fruit trees, it promotes flowering and fruiting while improving fruit quality. Application: Dilute and spray.

2. Urea: Provides nitrogen to support plant growth. Application: Dilute and spray, but avoid excessive use, as it may affect fruit quality.

3. Ammonium Sulfate: Contains nitrogen, phosphorus, and potassium, making it versatile for fruit trees. Application: Dilute and spray.

4. Trace Element Fertilizers: Such as iron, zinc, and copper, which enhance disease resistance by supplementing micronutrients. Application: Dilute and spray.

Proper foliar fertilization management can significantly boost longan tree yields and fruit quality. When selecting fertilizers, consider the tree’s growth stage, soil conditions, and market demands to choose appropriate types and dosages. Regularly observe plant responses and adjust strategies to ensure healthy growth and optimal fruit quality.
