What to do if peach tree leaves turn yellow

1. Foliar topdressing

(1) Specific reasons: If the tree is pruned too much, there will be very few branches and leaves left above the ground, and the above-ground and underground parts will lose balance. Furthermore, the death of a large number of roots will lead to overall nutritional imbalance. If this is a period of rapid growth, the leaves may turn yellow.

(2) Solution: Apply 0.3% urea to the leaves once a week for three consecutive times.

2. Spray pesticides to deal with pests and diseases

(1) Specific reasons: Such as "root cancer" and "root-knot nematodes", which can cause the leaves to turn yellow.

(2) Solution: After discovery, cut off the affected parts in time and then spray pesticides, such as Bordeaux liquid.

3. Provide sufficient light

(1) Specific reasons: Insufficient light causes chlorophyll to fail to form, causing the leaves to turn yellow and become thinner.

(2) Solution: Try to allow the plants to receive sufficient sunlight. In addition, attention should be paid to pruning to increase light transmittance.

4. Regulate water balance

(1) Specific reasons: Drought or flooding may cause leaves to turn yellow or even die.

(2) Solution: When rainfall is very small or when the rainy season begins, different measures need to be taken to adjust the water balance by watering in the early stage and draining in the later stage.

5. Thinning flowers and fruits

(1) Specific reasons: If there are too many fruits and the plant bears too much weight, nutrients will be insufficient, resulting in yellow leaves.

(2) Solution: Don’t just pursue yield, but also thin out the flowers and fruits and apply a reasonable load.
