The difference between dry and wet is too largeIf the plant is not watered for a long time, the leaves will first wilt and then turn yellow; or if it is not watered for a long time and then suddenly watered with a large amount of water, the plant will not be able to adapt and will turn yellow. Correct approach: Water strawberries only when the soil is dry and water them moderately. Changes in ambient temperatureIf strawberries are suddenly moved from the greenhouse to a windy place, they will turn yellow and drop leaves. The lack of sunlight will be detrimental to the photosynthesis of strawberries, and will also reduce leaf evaporation, leading to circulatory disorders in the plants. The correct way: plant strawberries in a place that is sheltered from the wind and has plenty of sunlight. Lack of trace elements or excessive fertilizationCorrect approach: If the lighting and watering are normal, the yellow leaves are caused by lack of fertilizer. You need to apply some fermented rice water under the soil beside the pot or apply 20 grains of compound fertilizer evenly every month. Metabolism and DiseaseCorrect approach: If strawberries are planted on a large scale, weeds and pests should be cleared first. You can spray 1000 times diluted 50% chlorpyrifos emulsifiable concentrate to prevent and control mole crickets, grubs and cutworms. If you grow it at home, remember to trim the dead leaves regularly or use pesticides appropriately. |
