What to do if the apple tree is burned by fertilizer roots (remedies for serious root burns caused by fertilizer application)

Too much fertilizer was applied to the apple tree, which burned the tree to death. Since the tree is already dead, there is no way to remedy it. We can only let nature take its course and replant or replant.

No matter how you apply fertilizer, if it's just burns, it's fertilizer damage. Even if it's serious, as long as the plant isn't completely dead, there's a way to save it.

As far as fertilizer damage is concerned, it is usually caused by too much fertilizer or too high a concentration of fertilizer. Different fertilization methods have different remedial methods.

There are several ways to alleviate the situation where the roots of apple trees are burned by fertilizers.

1. Watering and dilution

When you find that root burn has caused the branches and leaves to shrink, do not water immediately according to the soil moisture conditions. If the humidity is high, watering will cause root rot. If the soil moisture is low, you can water appropriately to alleviate the damage, but do not flood the plant with large amounts of water. Water frequently with small amounts of water.

2. Remove fertilizers

If fertilizer damage is discovered, the soil covering the fertilizer should be immediately removed to remove the undissolved fertilizer, reduce the amount of fertilizer, and minimize fertilizer damage.

3. Use conditioners

Spray chitosan + cytokinin + potassium dihydrogen phosphate on the leaves of the plants to supplement leaf nutrition, enhance plant resistance, and promote rapid recovery of plant growth. Never use bacterial fertilizers, which will release a lot of heat in a short period of time, thus aggravating root burn.

4. Root irrigation

Using fertilizers containing chitosan and amino acids can quickly restore the growth of plants and alleviate root burn, such as chitosan fertilizers.

The amino acid fertilizer contained in it can be quickly absorbed and utilized by the roots, alleviating the nutritional deficiency caused by root burn and strengthening the growth of the plant.

5. Wash and dry the roots

For trees with serious fertilizer damage, when digging up the covering soil to take out the fertilizer, you can also dig out several main roots of the tree at the same time and wash them with clean water.

After washing, the roots should be air-dried. Pay attention to the length of time to dry the surface of the roots. After drying, the roots should be buried in the soil immediately to restore to their original state.

【 Summarize 】

Fertilizer damage is very harmful to trees. If it is not handled in time, it is likely to result in tree death. Even if the fertilizer damage is minor, it is very troublesome to deal with, which is time-consuming, labor-intensive, and increases management costs.

Therefore, you must pay attention when applying fertilizer and determine the type, quantity, and method of fertilizer according to the actual situation of the tree to avoid fertilizer damage.
