What is the best fertilizer for apple trees?

When to fertilize apple trees

Generally speaking, there are five main periods for applying fertilizer to apple trees, namely the budding period, after the flowers fall, the second fruit swelling period, the fruit nutrient conversion period and autumn basal fertilizer application.

What fertilizer to use for apple trees

When fertilizing apple trees, it is generally more appropriate to apply nitrogen fertilizer. Appropriate application of nitrogen fertilizer within a certain range can increase the number of branches and leaves of the plant, enhance tree vigor and increase yield.

In addition, it is necessary to supplement apples with appropriate phosphorus and potassium fertilizers, which can not only increase the yield of apples, but also promote the growth and development of the plant's root system and promote the root system to extend deep into the soil, thereby improving the fruit tree's drought resistance.

How to fertilize apple trees

When fertilizing apple trees, you can fertilize through the roots, because the roots of fruit trees are the main organs for absorbing nutrients. Applying fertilizer to the roots can increase fertilizer.

In addition, you can also spray fertilizer on the leaves of the apple tree. If the plant grows weakly and the leaves are turning yellow or light yellow, this indicates that the plant is lacking in oxygen and iron. You should mainly spray nitrogen fertilizer to alleviate the symptoms.

Apple tree fertilization precautions

When fertilizing apple trees, you need to be careful not to apply too much fertilizer to avoid fertilizer damage. In addition, the plant has many large stomata on the back of its leaves, and fertilizer is easily absorbed. Therefore, when spraying fertilizer, you should focus on the back of the leaves from top to bottom, so that the fertilizer liquid will slide down to the bottom of the leaves.
