In order for fruit trees to bear plenty of fruit, the right care in spring is crucial. This also includes fertilization. As early as February, the trees can be supplied with the necessary nutrients.
Fertilizing fruit trees: In February the right time for young trees is
The temperatures begin to rise in February and theRest phase of the fruit treesSlowly comes to the end. Now the growth phase and the time of new shoot begins. For this purpose, the fruit trees use nutrients that they have saved in their tribes, roots and branches before winter.
These reserves are usually consumed until the beginning of flowering. Now the trees begin to absorb nutrients over the ground.
Accordingly, young plants have less storage capacity, consume the reserves faster and then need new nutrient sources in mid -March.
But old and large fruit trees can also benefit from an early fertilizer - for example if they were sick last year or if they were affected by pests. You will strengthen these additional nutrients.
In February the right time for fertilizer is, since the fertilizer needs between 4 and 6 weeks until it is decomposed and can be absorbed via the root system. Anyone who fertilizes the soil in February ensures that the fruit trees in March and April have enough nutrients for leaf and flower formation.
The trees need these important nutrients
There are a total of 16 micro and macronutrients that need fruit trees to grow healthy and strongly and to wear plenty of fruits. These are carbon, hydrogen, oxygen, phosphorus, potassium, nitrogen, sulfur, calcium, iron, magnesium, chlorine, boron, copper, manganese, zinc and molybdenum.
In spring, fruit trees mainly need nitrogen, phosphorus, potassium and maybe some calcium - especially the macronutrients. A good idea is to test the pH of the soil and have the soil structure checked in a laboratory. In this way, deficiencies can be determined at an early stage and covered by fertilizers.
Defects can also be determined later due to the growth image - but then it is already too late to cover them by fertilizing.
If you want to do without fertilizers completely, you can supply the soil with ripe compost instead. This should be incorporated into the earth at least 6 to 8 weeks before the flowering period of the trees. Because compost is decomposed over a longer period of time.
Fertilize stone fruit really
In the case of fruit like cherries and peaches, the flowers open first and only then does the growth period begin. NPK fertilizer is well suited, which are a mixture of 10 parts of nitrogen, 10 parts phosphorus and 10 parts of potassium.
If you choose organic fertilizers, you can mix the stable manure, compost, rock flour or horn shavings. Proceed as follows:
1. First work a thin layer of tire compost into the ground.
2. Add 120 g per tree horn flour.
3. Place a thick layer of bark around the root area.
Care fruit with nutrients
Unlike stone fruit, core fruit trees such as apples and pears first drive out vigorously and then form their flowers. A combination of leaf fertilizers and natural fertilizers proves to be optimal for you. The leaf fertilizer delivers important calcium and can significantly improve the fruit quality and durability of the fruits. The natural fertilizer can also be made. Simply for this purpose:
- 70 liters of mature garden compost
- 80 g – 90 g Hornmehl
Mix well and incorporate into the root area of the trees.
- Add rock flour only if necessary to regulate the pH of the soil. Diaba flour is used when the pH is below the recommended 6.5-7. If the floor in the orchard is alkaline (over 7), the basalt flour is ideal.
In addition, a leaf fertilizer can supply the fruit trees with calcium. Duments that have grown in a low -calcium floor carry fruits with a bitter taste. The leaves are sprayed with the leaf fertilizer every 10 days. The first application can take place immediately after the end of the flowering period.
Find nutrient deficiency in good time
A lack of nutrients can be determined in spring the fastest and easiest. Measure the shoot - fruit trees should increase between 30 cm and 60 cm per year.
If this is not the case, it is worth oneTo remove soil sampleand to be analyzed. In this way, defects can be remedied in late summer and autumn.
