While general nutrient deficiency leads to a decline in 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.
Why does my cherry tree have yellow leaves?
Yellow leaves on the cherry tree can be due to a magnesium deficiency, an insufficient supply of minerals such as iron and nitrogen or chlorosis. Magnesium-containing fertilizer, soil improvement and a consistent supply of water can help. In stubborn cases, a soil analysis may be necessary.
Magnesium deficiency causes yellow leaves
Magnesium is needed for the plant's functioning photosynthesis, 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 can be seen 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 replanting have been used up and not replenished, this can contribute to deficiency symptoms. Excessive fertilizing with complex complete fertilizers can also lead to the cherry tree not receiving enough magnesium.
Chlorosis occurs due to a lack of minerals
Basic deficiency of minerals, such as: B. Iron and nitrogen, but also too high a s alt content in the soil promote the development of chlorosis, which is also called “jaundice” in plants. If the yellowing of the individual leaves is not paid attention to, the disease will continue to progress.
Prolonged drought can also lead to the progression of chlorophile deficiency. Not only older but also younger leaves increasingly turn yellow, which are eventually shed if magnesium and iron deficiency persists. The cherry tree no longer looks he althy and is aging prematurely.
Remedy
The solution to the problem is obvious: a fertilizer containing magnesium (€10.00 on Amazon) should be administered specifically. In conjunction with soil improvement and an even supply of water, the leaves of the cherry tree regain their he althy green color. In particularly stubborn cases, a soil analysis should be carried out to determine which nutrients are missing or in excess. The resulting fertilization recommendation helps to keep the cherry tree he althy.
Tips & Tricks
Magnesium or iron can be added by spraying the leaves directly. This process works faster than dissolving in irrigation water or spreading and incorporating it into the soil.
