Perfume lemon is a kind of lemon that grows in Bao Dao. It blooms all year round and keeps the fruit, which is different from the bitter taste of other lemons. This kind of lemon has a slender fruit shape, a sweet skin, and is big and seedless. It can be sliced directly and soaked in water for drinking, with rich aroma. So it is called "perfume lemon", also called "seedless lemon", which is the holy product of lemon! I often meet flower friends and ask what to do if the lemon leaves of perfume turn yellow. Here's Uncle Gardener to introduce the reasons and solutions for the yellowing of lemon leaves in perfume! 1. Yellow flowers lack iron and elements to cause yellowing symptoms of lemon leaves: yellow flowers lack elements, such as yellow leaves with nitrogen deficiency symptoms and yellow veins with iron deficiency symptoms. Solution: supplement fertilizer containing yellow flowers or iron. 2. Malnutrition causes the leaves of lemon trees to turn yellow. Symptoms: After flowering, the leaves turn yellow and fall off. Solution: If the leaves turn yellow due to malnutrition, you can spray potassium dihydrogen phosphate. This fertilizer contains a lot of trace elements besides nitrogen, phosphorus and potassium. Usage: Spray 0.3% on the leaf surface every half month in the growing season, and smear it in the basin once. 3. Root rot causes the leaves of lemon trees 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 the scraped part is coated with copper 100 times and thiophanate-200-300 times, and the wound is covered with soil after healing. 4. Symptoms of yellow leaves of lemon trees caused by pests: visible pests. Solution: Control insects by hand or spray corresponding chemicals. 5. Normal metabolic symptoms: the leaves turn yellow and continue to grow new buds after falling. Solution: Maintain according to the daily maintenance method. 6. Other unexplained symptoms: excessive watering or soil moisture loss. Solution: reduce the amount of water in the rice basin or loosen the soil. In short, the yellow leaves of perfume lemon are caused by iron deficiency, malnutrition, root rot, insect pests, normal plant metabolism, waterlogging or drought.
