Perfume lemon is a kind of lemon cultivated in Taiwan Province Province, Baodao. It is different from other lemons in bitterness. This kind of lemon fruit is slender in shape and seedless in size, so it can be directly sliced and soaked in water, so it is called "perfume lemon" or "seedless lemon" and is a sacred product in lemon! I often meet flower friends and ask what to do if the lemon leaves of perfume turn yellow. Here's Uncle Gardener's introduction to the causes and solutions of yellowing of lemon leaves in perfume!

1. Iron deficiency and yellow flowers lead to the yellowing of lemon leaves.

Symptoms: yellow flowers lacking elements, such as yellow leaves with nitrogen deficiency and yellow veins with iron deficiency.

Solution: targeted supplementation of yellow flowers or iron-containing fertilizers.

2. Malnutrition causes lemon leaves to turn yellow.

Symptoms: After flowering, the leaves turn yellow and fall off.

Solution: When the leaves become Huang Shi due to malnutrition, potassium dihydrogen phosphate can be sprayed. This fertilizer contains a lot of trace elements besides nitrogen, phosphorus and potassium. Usage: Spray 0.3% on the leaf surface and apply it to the soil in the basin, once every half month in the growing season.

3. Root rot causes lemon leaves to turn yellow.

Symptoms: the bark is rotten and smells of distiller's grains.

Solution: Root rot is often caused by too much water in the basin or too much fertilization. The diseased part and a small amount of healthy tissue can be scraped clean with a sharp knife, and 65,438+000 times of red copper and 200-300 times of topaz are applied to the scraped mouth, and the wound can be covered with soil after healing.

Insects cause the leaves of lemon trees to turn yellow.

Symptoms: visible pests.

Solution: Manually exterminate insects or spray corresponding chemicals.

5. Normal metabolism

Symptoms: Leaves turn yellow and continue to sprout after falling.

Solution: just follow the daily maintenance method.

6. Other unknown symptoms

Reason: It may be that there is too much watering or the soil can't keep moisture.

Solution: reduce the amount of water in the rice basin or loosen the soil.

In a word, the yellow leaves of perfume lemon are caused by iron deficiency, malnutrition, root rot, insect pests, normal plant metabolism, waterlogging or drought.
