Last Updated: 2024/11/06, There are five reasons why peach leaves turn yellow. The first is that the pruning is too heavy and urea foliar topdressing is needed. If the second disease and insect pest is caused, it is necessary to spray the corresponding chemical. The third is the lack of light, it is necessary to provide sufficient light as far as possible, and appropriate pruning to ensure light transmission. The fourth is drought and waterlogging, which needs to ensure water balance. Fifth, if you hang too many fruits, you need to sparse flowers and fruits.

1. Foliar topdressing

(1) the specific reason: if the pruning is too much, there are few branches and leaves left in the aboveground part, then the aboveground and underground parts will lose balance. In turn, the decline of a large number of roots will lead to overall malnutrition. If this is the time to grow rapidly, it may cause the leaves to turn yellow.

(2) solution: foliar topdressing with 0.3% concentration of urea once a week, three times in a row.

2. Spraying to deal with diseases and insect pests

(1) specific reasons: such as "root cancer", "root knot nematode" and so on, can lead to yellowing of leaves.

(2) solution: after discovery, cut off the parts affected by diseases and insect pests in time, and then spray chemicals, such as Bordeaux liquid.

3. Provide sufficient light

(1) specific reasons: lack of light, chlorophyll can not be formed, leaves may turn yellow, but also may become thinner.

(2) solution: let the plant receive enough sunlight as much as possible. In addition, attention should be paid to pruning to increase the transmittance.

4. Adjust the water balance

(1) specific causes: drought and waterlogging may cause leaves to turn yellow, or even die.

(2) solution: when the rainfall is very small, or when entering the rainy season, different measures need to be taken, watering in the early stage and drainage in the later stage, in order to adjust the water balance.

5. Thinning flowers and fruits

(1) specific reasons: if there is too much and too much weight, there will be insufficient nutrients and yellow leaves will appear.

(2) solution: do not only pursue output, but also need to thinning flowers and fruits and bearing a reasonable load.
