What fertilizer is good for fruit trees?

Overview of Fruit Tree Fertilization

Fruit trees refer to trees whose fruits are edible, such as apple trees, pear trees, citrus trees, apricot trees, peach trees, etc. Many people think that only apple trees are fruit trees, which is actually a misunderstanding of fruit trees.

Generally speaking, if you want to fertilize fruit trees, you can apply farmyard manure, organic fertilizer, or fermented farmyard manure. These are high-quality base fertilizers for fruit trees. These fertilizers have relatively long fertilizer effects, mild fertilizer effects, and more comprehensive nutrients, which can provide sufficient nutrients for the growth of fruit trees.

What fertilizer is good for fruit trees?

Normally, different fertilizers need to be applied to fruit trees at different times. Organic fertilizer and inorganic fertilizer need to be applied 5-10 days before the beginning of spring. The combination of the two can promote plant germination. The specific fertilizers applied are manure, urea, calcium sulfate, potassium sulfate, zinc sulfate, boric fertilizer and ferrous sulfate.

After the fruit trees sprout, if the branches grow weakly or sprout unevenly, it is necessary to apply urea, calcium sulfate and potassium sulfate to fertilize and strengthen the branches.

How to fertilize fruit trees

The method of fertilizing fruit trees is relatively simple. Just dig a trench on both sides of the grape vine, apply the prepared organic fertilizer, then fill it and water it.

When digging trenches and applying fertilizer to fruit trees, be careful not to dig trenches in the same location every time you apply fertilizer, as this will damage the newly grown roots from the previous year.

1. Fertilization in spring

Spring fertilization is generally carried out around April. At this time, nitrogen is one of the nutrients that fruit trees require in larger quantities, so it is necessary to apply nitrogen-containing fertilizers to the plants in time to promote vigorous growth.

2. Fertilization in summer

In summer, fertilizer is generally applied from June to July. At this time, fruit trees have a relatively high demand for phosphorus, so fertilizers containing phosphorus need to be applied to them to promote fruit enlargement.

3. Fertilize in autumn

It is more appropriate to apply fertilizer in mid-October in autumn. At this time, fruit trees need a certain amount of potassium, so it is necessary to apply fertilizer containing potassium to give the plants sufficient nutrients to resume growth.

4. Fertilize in winter

It is more appropriate to apply fertilizer in winter from November to December, and the fertilizer should mainly be decomposed human feces or urine or quick-acting fertilizers such as urea and wood ash.

Points to note when fertilizing fruit trees

1. When fertilizing fruit trees, in order to prevent fertilizer damage and root burn, you should not use too concentrated fertilizers, and the amount applied should not be too much.

2. To prevent the leaves of fruit trees from turning yellow, it is necessary to use a combination of inorganic fertilizers and organic fertilizers, and a combination of chemical fertilizers and microbial fertilizers to achieve full nutrient fertilization, which can prevent the leaves from turning yellow.

3. Fruit trees are light-loving plants and have high requirements for light, so after fertilizing, it is necessary to ensure sufficient light to promote the growth and development of the grape vines, and to increase yield and quality.
