The best fertilizers for fruit trees to promote optimal growth.

Besides meticulous plant care, choosing the right fertilizer plays a crucial role. Selecting the appropriate fertilizer at the right time and in the right dosage helps plants grow healthily and produce plump, juicy fruits. Viet Nga Fertilizer would like to share some of the most popular and widely used fertilizers for fruit trees among orchard owners.

The best types of fertilizers for fruit trees.

Currently, the market offers many different types of fertilizers for fruit trees, suitable for each stage of plant growth. Growers should equip themselves with knowledge about these fertilizers to ensure better fruit tree development.

Fertilizing fruit trees with earthworms.

Vermicompost is rich in macronutrients and micronutrients. It’s a natural fertilizer, safe and beneficial for plants, helping to improve soil quality. Applying vermicompost will not negatively impact plants.

Fertilizers for fruit trees contain high levels of potassium, which helps improve fruit quality and flavor during the fruiting stage. Bat guano or chicken manure are organic fertilizers that meet this requirement. These types of fertilizers are good for fruit trees, helping to produce abundant and larger fruits with richer and more fragrant flavors.

Composite fertilizer

Compound fertilizers, or NPK compound fertilizers, contain many essential components for fruit trees. Many compound fertilizers are available on the market with varying nutrient ratios and are used at different stages of plant growth.

The right dosage of compound fertilizer will yield quick results. However, prolonged use can compact the soil, and excessive amounts can cause root burn and plant shock. Therefore, growers should use it alternately with or in combination with other organic fertilizers for better results.

Fish protein fertilizer for fruit trees.

This type of fertilizer stimulates healthy plant growth and rapid development, helping plants produce branches and leaves faster. The rich minerals and high nitrogen content in fish fertilizer provide essential nutrients for vigorous fruit tree growth. It’s also a safe source of nutrients that doesn’t degrade the soil. Therefore, adding this fertilizer helps fruit trees produce more fruit.

The scientifically correct and effective way to fertilize fruit trees.

Choosing the wrong fertilizer for fruit trees will hinder their growth, even in fertile soil. Below, we share with farmers the scientifically correct way to apply fertilizer:

• After harvesting: This is the stage where nitrogen fertilizer is needed to replenish the plant’s nutrients, as fruit trees lose nutrients during this period.
• During the flowering preparation stage: Growers should increase the proportion of potassium and phosphorus fertilizers and decrease the proportion of nitrogen to encourage the plant to produce more leaves.
• Post-fruiting stage: For about the first month, the fruit grows slowly, so it’s not necessary to provide a lot of nutrients, but the plant must not be deficient in nutrients. At this time, a combination of foliar and root fertilizers in a 1:1:1 ratio can be used.
• Rapid fruit development stage: This stage requires accelerated growth to promote faster fruit development. For trees like rambutan, mango, or longan, the NPK fertilizer ratio should be 1:1:1; for citrus trees like durian, jackfruit, or pomelo, the NPK ratio should be 2:2:3. Short-growing trees should be fertilized once, while long-growing trees should be fertilized 2-3 times.
• Stage of larger and ripening fruit: This is the stage when the fruit has fully grown. To ensure good quality and a more attractive appearance, the appropriate NPK fertilizer ratio is 1:1:2.

Some important notes when fertilizing fruit trees.

Tree growers should note that when fertilizing fruit trees, apply the fertilizer around the tree’s canopy. Because the tree’s root absorption capacity is no longer as efficient, when fertilizing, maintain a distance of 1m – 1.5m from the base of the tree.

Fertilizers are easily washed away by water, so dig trenches or holes beforehand before applying fertilizer to fruit trees. Once fertilizer has been applied, water is needed to dissolve it and allow it to penetrate the roots, ensuring the plant receives more nutrients. If fertilizer lacks water, it will not be able to fully exert its effect on the plant.

Choosing the right fertilizer for fruit trees is crucial for healthy growth and maximum yield. The appropriate fertilizer should be applied according to the tree’s growth stage, and the fertilization method must be correct.
