Best Fertilizer For Longan Tree

Longan is a tropical fruit tree with pinnate leaves, white flowers, and edible fruits. It is native to Southern China, Southeast Asia, and Northern Australia. Longan trees are well known for their aromatic fruits that are used to make various desserts and drinks. The fruit of the longan tree has been used as herbal medicine in traditional Chinese medicine for centuries.

Longan trees need a lot of sunlight and well-drained soil to grow well. They also require regular watering during dry periods which can be done by making furrows around the plant or by sprinkling water every few days.

The nutrient requirements of longan trees vary depending on different factors such as age, type of soil, etc but in general, they need high amounts of nitrogen, phosphorus, and potassium (NPK). For best results, you should use a fertilizer that contains all three macronutrients in equal amounts (1:1:1) since this will provide your plants with balanced nutrients that will keep them healthy throughout their life cycle.

Fertilizing a longan tree is essential for enhancing the quality and yield of its fruits. It improves the quality of the fruit, minimizes the size of small and large fruits, and extends the fruiting period. During the material period, fertilizing the tree should be done based on the tree’s age and potential. This process will promote flower bud differentiation while preserving the flowers and strong fruits.

Potassium chlorate

For best results, potassium chlorate is sprayed directly on the ground underneath the canopy of the longan tree. This fertilizer increases the amount of humidity within the canopy. However, it is important to use it in the right amount, as too much will result in yellowing leaves. This is because chlorophyll is essential for leaf and flower growth. Without chlorophyll, plants will abandon yellow leaves. Potassium chlorate is best applied on the ground directly under the canopy, which is washed into the soil.

Another type of fertilizer is potassium chlorate, which contains calcium and magnesium. It is granulated or synthetic and has a particle size of 18 mm. This type of fertilizer is highly recommended for the irregular season in southern China. Using this fertilizer will help the longan tree blossom. The following is a simple method to apply this fertilizer:

In a nutshell, potassium chlorate is the best fertilizer for longan trees. This chemical has 32% K and does not require registration with the Australian Pesticides and Veterinary Medicine Authority. Several studies have indicated that potassium chlorate increases flowering and fruit production in longan trees. However, it has some adverse effects on the plant. It can also be toxic to the plant.


To grow a healthy longan tree, you should feed it with an equal amount of potassium, phosphate, and urea. The ratio of these nutrients should be varied to suit the growth stage of the tree. Young trees are usually given 0.5 to 75 kg farmyard manure and 100 g P2O5 per tree. Fertilizer applications should be spaced out three to four times a year.

After the first fruit is harvested, apply 0.2% urea and magnesium sulfate to the leaves. Make sure that the spray is uniform and that no drips occur. This is to help the tree rejuvenate and stabilize itself. This fertilizer should be applied at least four times, beginning in late February and continuing through the rainy season in May. In addition, foliar sprays containing calcium nitrate are effective at enhancing flower initiation.

When it comes to soil, longan trees grow best on sandy, calcareous, and rocky soils. The best soil for growing a longan tree is well-drained. It can grow well in most types of soil but is not ideal for all. In addition to sandy soil, longan trees can grow in rocky, calcareous, and phosphate-rich soils.


To get good longan fruits, fertilization is essential, especially pre-flowering. Fertilizing the tree before flowering will promote the development of flower spikes and the differentiation of flower buds. Pre-flowering fertilization can also be beneficial for post-harvest trees because it will supplement the tree’s nutrient deficit in late flowering. In addition to fertilization before flowering, fertilization of the tree before the tip of the fruit can enhance the quality of the fruit and prevent premature cropping. Urea-urea is a good fertilizer for longan trees.

In addition to improving fruit quality, proper fertilization of longan trees can also promote the growth of the plant, increase soil fertility, improve the mass structure of the soil, and enhance the overall growth of the plant. Reasonable fertilization can also promote flower bud differentiation and reduce fruit and flower drop. Proper fertilization can also promote the production of fruit and flower, reducing the number of small and large fruits, and extending the tree’s lifespan.

If you wish to plant a longan tree in your backyard, you should make sure to choose a location with adequate drainage. Longan trees grow rapidly, and homeowners should keep a planting distance of at least 25 feet away from other trees and structures. If you plant them too close, they may not grow well and will not produce much fruit. It’s recommended to plant longan trees in a mound of native soil.

Ammonium nitrate

Among the many fertilizers for longan trees, ammonium nitrate is the most effective one. This type of fertilizer is known to increase the amount of N, P, and K in the plant’s tissues. It has a 75:25 ratio. It also helps improve the efficiency of nitrogen utilization by pepper. However, studies on urea metabolism and its effects on plant growth are still scarce.

The amount of nitrogen in the soil depends on the type of plant. In general, ammonium nitrate is better for summer applications compared to urea. Other forms of nitrate can leach out during heavy rain. Therefore, it is important to know how much nitrogen is necessary for longan. Adding potassium to the soil helps it absorb nitrogen. Insufficient potassium can reduce fruit quality.

The application of a single N source promoted nitrogen metabolism and reduced ammonia toxicity in the plant. When combined with a double application of NH4+-N, the growth of four plants was significantly restricted. The application of pure NH4+-N decreased the production of glutamate and GDH-3. In addition, ammonia inhibits K+ and Ca2+ absorption.

Ammonium sulfate

Ammonium sulfate is one of the best fertilizers for longan trees because of its ability to promote healthy growth. Longan trees need 21-0-0 ammonium sulfate to grow and yield their highest amount of fruit. The recommended application rate is 1 pound per square foot of soil for second and third-year trees, and 2 pounds per square foot for fourth-year trees. It is important to remember that fertilizing your tree can make or break your harvest.

Ammonium sulfate is inexpensive and widely available. Slow-release fertilizers are also a good option, but make sure to follow label directions. In addition, slow-release fertilizers won’t burn the plants surrounding your target trees. Fertilizer is the tree’s food, so you don’t want to overdo it. Ideally, one pound of 21-0-0 per inch of trunk diameter will be applied in early spring and one pound per inch of root volume in second-year trees.

Longan trees are tolerant of windy conditions. Withstanding water during late summer and early fall can promote fruiting. However, you shouldn’t overwater the tree, as this will cause root rot and reduce fruit production. Avoid overwatering the tree if you have lawn sprinklers on a timer. While the plant tolerates some flooding, excessive watering can damage the tree.

Nitrogen sulfate

If you’re growing a longan tree in your yard, make sure to use a balanced fertilizer, with equal proportions of N, P, and K. You should fertilize your tree every month in spring and autumn. Depending on its size, you may need as little as 1.5 to 2.25 kg of fertilizer, or 3.3 to 5 pounds, per tree. You should avoid using sprinklers on timers because they can lead to root rot. Apply fertilizer to the soil 10 inches from the trunk and one foot from the drip line.

Planting a longan tree is easy, but be sure to keep the soil dry. If you live in a cold climate, withholding water in late summer will prevent it from excessive vegetative growth and will promote flowering in the spring. You should also mulch the area around the trunk with at least 10 cm (4 inches) of mulch, which will protect it from weeds, keep the soil moist, and suppress weeds. Longan trees should be planted in a location that doesn’t flood during the summer, as this will lead to poor pollination and fruit production.

Planting a longan tree is important, and should be done carefully. Nursery longan trees typically come in 3-gallon containers, with a height of two to four feet from the media used for soil. If you are planting a large longan tree in a container, it may be root bound, which will make it difficult for the roots to grow in the ground.

Sulfur sulfate

A good fertilizer for the longan tree is a blend of nitrogen, potassium, and sulfur. It is recommended to use a six-to-six-pack fertilizer, with 20-30% nitrogen coming from organic sources. A single application of fertilizer will cover about 227 grams of the tree, while four to six splits of fertilizer are sufficient to maintain the desired growth rate.

The right amount of fertilizer for longan trees will vary depending on the type of soil they are in. Soil that is too acidic may inhibit growth, while a pH that is too alkaline can cause the plant to not produce flowers or fruit. Soil that is too acidic will not support longan tree growth. To provide the tree with enough nutrients, fertilizer mixes can be used in the soil and the tree’s roots.

Sulfur is an essential nutrient for plants. It helps in the development of chlorophyll, a pigment responsible for absorbing sunlight. The chlorophyll in the leaves improves photosynthesis. It also helps in the development of stronger immune systems. Sulfur also works as a strong fungicide and disinfectant. It inhibits fungi, powdery mildew, and various pests and diseases.
