How much fertilizer should be used for fruit trees ?

To ensure flourishing health and abundant production of succulent fruits, your fruit trees require adequate nutrition through the judicious use of fertilizers. However, it is important not to exceed the necessary doses, as this could negatively affect their health. The key to success lies in determining the precise amount of fertilizer required, which depends on several factors such as the age, type, size of the tree and the characteristics of the soil. Developing a personalized nutrition plan for each tree is therefore crucial to ensure their sustainable development and optimize their yield. Therefore, understanding the specific fertilizer needs of your fruit trees is essential for their maintenance and productive growth.

Understanding the nutrient needs of fruit trees

Fruit trees need three main nutrients to thrive: nitrogen (N), phosphorus (P), and potassium (K).

Nitrogen (N): Promotes leaf and branch growth.

Phosphorus (P): Stimulates root formation and fruit production.

Potassium (K): Strengthens resistance to diseases and improves fruit quality.

Assessing soil fertility

It is essential to conduct a rigorous assessment of soil fertility before fertilizing fruit trees. A soil test diagnosis reveals nutrient concentrations and thus guides the adjustment of fertilizer inputs, ensuring targeted nutrition and preventing any excess harmful to tree health.

Determining the amount of fertilizer based on free age and species

- Young trees (1 to 3 years): Apply a starter fertilizer rich in phosphorus and potassium to promote root development. A moderate amount of nitrogen can also be added.

- Mature trees (4 years and older): Fertilizer needs vary depending on the species and fruit production. In general, a balanced NPK fertilizer (10-10-10 or similar) can be used. Follow the manufacturer's instructions to determine the appropriate amount to apply based on the size of the tree.

Fertilizer application timing

- For young trees (less than 3 years old): It is recommended to fertilize them once in the spring, just after the frost period.

- For mature trees: Two fertilizations can be beneficial. The first should take place in the spring, after the last frost, and the second in late summer or early autumn.

Fertilizer application methods

- Granular fertilizer: Spread the fertilizer evenly around the base of the tree, following the manufacturer's instructions. Generous watering is necessary to initiate the release of nutrients into the soil.

- Liquid fertilizer: Prepare the liquid fertilizer solution according to the manufacturer's instructions and pour it around the base of the tree. Thorough watering is recommended to facilitate nutrient uptake.

- Foliar fertilizer: Mix the foliar fertilizer with water according to the manufacturer's instructions and spray gently onto the foliage until it is just moist. It is advisable to avoid applying this foliar fertilizer during sunny hours or when the weather is hot and dry to prevent any risk of leaf burn.

Signs of over-fertilization

- Leaf burn
- Excessive leaf growth at the expense of fruit production
- Premature leaf drop
- Weakened tree and increased susceptibility to diseases

To ensure optimal growth and an abundant harvest of delicious fruits, it is essential to fertilize your fruit trees properly. It is important to follow the manufacturer's recommendations and adjust the amount of fertilizer according to the age, variety, and size of the tree, as well as the quality of the soil. Avoid over-fertilizing, as this can damage your trees. Finding the right balance is therefore essential.
