While general nutrient deficiencies lead to reduced growth, fertility and resistance, the lack of individual nutrients results in characteristic deficiency symptoms. It is therefore important to supply the cherry tree with the missing nutrients in sufficient quantities at a suitable time.
Magnesium deficiency causes yellow leaves
Magnesium is required for the functioning photosynthesis of the plant, which in turn is essential for the survival of all plants. If the green leaves of the cherry tree begin to turn yellow prematurely and partially, this indicates a magnesium deficiency in the soil. The typical leaf discoloration shows between the leaf veins, which remain green.
Overly compacted, wet soils and light, acidic sandy soils often have insufficient magnesium content. If the nutrients from the compost added when planting new plants have been used up and not replenished, this can contribute to deficiencies. Excessive fertilization with complex complete fertilizers can also lead to the cherry tree not being adequately supplied with magnesium.
Chlorosis arises from a lack of minerals
Basic lack of minerals, e.g. B. Iron and nitrogen, but also too high a salt content in the soil favor the development of chlorosis, which is also called "jaundice" in plants. If no attention is paid to the yellowing of the individual leaves, the disease will progress further.
The persistent drought can also lead to the progression of the chlorophile deficiency. Not only older, but also younger leaves are increasingly turning yellow, which are eventually shed if there is a persistent magnesium and iron deficiency. The cherry tree no longer looks healthy and ages prematurely.
remedy
The solution to the problem is obvious: a fertilizer containing magnesium should be administered in a targeted manner. In conjunction with soil improvement and an even supply of water, the leaves of the cherry tree regain their healthy green color. In particularly stubborn cases, a soil analysis should be carried out to determine which nutrients are missing or in abundance. The resulting fertilization recommendation helps to keep the cherry tree healthy.
tips and tricks
Magnesium or iron can be added by spraying the leaves directly. This method works faster than dissolving it in irrigation water or spreading it out and working it into the ground.
