How to deal with the apple tree being burnt by chemical fertilizer

First, spray clean water on the plant affected by the chemical fertilizer to reduce the residue of the pesticide on the plant surface and prevent further damage. When spraying water, you can add white sugar in a ratio of 100:1 because the sugar water can further dilute the pesticide and reduce the damage. Next, use a pesticide to spray the plant, which can include certain cytokinins and brassinolide.

If too much chemical fertilizer is applied to the apple tree, it can cause fertilizer damage and burn the tree. Since the tree is already dead, there's no way to save it, and you can only let it be and consider planting a new one.

No matter how the fertilizer is applied, if only the burn occurs, it indicates fertilizer damage. Even if it is severe, as long as the tree is not completely dead, there are ways to save it.

In general, fertilizer damage is usually caused by excessive fertilizer application or too high concentration of chemical fertilizer. Different fertilization methods require different remedies.

There are several methods to alleviate the situation when the apple tree is burnt by chemical fertilizer.

1. Water dilution

When the roots are burnt and the branches and leaves start to shrink, you should consider the soil moisture level and not water immediately. If the soil moisture is high, watering can cause root rot. If the soil moisture is low, you can water moderately to alleviate the damage, but avoid excessive watering and instead water frequently with small amounts.

2. Remove chemical fertilizer

If fertilizer damage is detected, immediately remove the topsoil covering the fertilizer and remove the undissolved fertilizer to reduce the amount and the damage.

3. Use regulators

Apply chitin, cytokinins, and potassium dihydrogen phosphate to the plant leaves to supplement foliar nutrition, enhance plant resistance, and promote rapid recovery. Never use bacterial fertilizer, as it will release a large amount of heat in a short time, further exacerbating the root burn.

4. Root irrigation treatment

Using fertilizers containing chitin and amino acids can quickly restore the plant's growth and alleviate the root burn, such as chitin fertilizers.

The amino acid fertilizers can be quickly absorbed and utilized by the roots, alleviating the nutritional deficiency caused by root burn and strengthening the plant's growth.

5. Water washing and drying root treatment

For severe fertilizer damage, when removing the fertilizer, you can also dig out several main roots of the tree and wash them with clean water.

After washing, dry the roots and then immediately cover them with soil to restore their original condition.

【Summary】

Fertilizer damage can cause significant harm to the tree, and if not treated in time, it may lead to tree death. Even if the fertilizer damage is mild, it can be troublesome and time-consuming to handle, increasing management costs.

Therefore, special attention should be paid to fertilization, determining the type, amount, and method of fertilization according to the actual condition of the tree to avoid fertilizer damage.
