What fertilizer is best for fruit trees?

At all stages of fruit tree growth, reasonable fertilization is the key to improving the healthy growth and yield of fruit trees. Only by mastering the principles of fertilizing fruit trees can we reduce the occurrence of more problems. Let’s learn together what is the best fertilizer for fruit trees?

1. Basic principles of fertilization

Autumn fertilization: Autumn, one month before leaf fall, is the best time to apply basal fertilizer. In addition, the time from leaf fall to freezing or from spring thaw to germination is also an appropriate time to apply fertilizer.

Organic fertilizer : It is recommended to increase the use of microbial organic fertilizer to promote tree recovery, flower bud differentiation, and reserve nutrients for next year's flowering and fruiting.

2. The importance of potash fertilizer

Potassium: As an essential element for plant growth, potassium helps activate enzymes in plants, enhances photosynthesis, promotes the metabolism of sugar and protein, improves plant resistance to stress, and improves product quality.

3. Application of slow -release fertilizer

Slow-release fertilizer: With the development of technology, slow-release fertilizer has gradually been widely used in fruit tree fertilization due to its advantages such as high efficiency and environmental protection. Proper use can promote tree vigor, improve fruit quality and yield.

4. The role of trace elements

Trace Elements: Although required in small quantities, trace elements such as boron, zinc, calcium and silicon have a significant impact on fruit tree growth and fruit quality. Reasonable application of these elements can increase fruit coloring, firmness and storage stability, and improve the disease resistance of fruit trees.

5. The best time to fertilize

Before flowering: During the budding and flowering period of fruit trees, apply quick-acting fertilizer appropriately to supplement nutrients and increase the fruit setting rate.

After flowering: apply fruit-stabilizing fertilizer to promote new shoot growth and photosynthesis and reduce physiological fruit drop.

Before flower bud differentiation: apply appropriate amounts of nitrogen, phosphorus and potassium fertilizers to improve photosynthetic efficiency and promote flower bud differentiation.

In the later stage of growth: apply fruit-enhancing fertilizer to increase yield and fruit quality and promote flower bud differentiation.

Before and after fruit picking: Apply tree-protecting fertilizer to restore tree vigor and enhance the ability to resist frost damage.

To sum up, these are the points that need to be paid attention to when fertilizing fruit trees. Different fruit tree varieties have different emphases at different growth stages.
