First, timely shading.
The dead leaves of celery leaf peony are likely to be sunburned by strong light, especially if the strong light in summer afternoon cannot be stopped in time, it will be sunburned in the sun, which will easily wither and even turn yellow slowly, hindering growth. When the light is strong, you must block it. For ground planting and maintenance, it is necessary to build a sunshade net for shading. Potted plants should be moved to a cool and ventilated place in time to make them spend the summer better.
Second, reduce watering.
Qin likes humid environment, but he is not tolerant of waterlogging. If you water too much at a time, or water too often, it will not be absorbed. After a long time, it is easy to leave water, hinder root respiration, make root retch easily, and leaves will wither. In this case, it is necessary to stop water, drain water, ventilate more and evaporate water. Pay attention to reduce water accumulation in the later period, it can be slightly wet in the growing season, and water should be controlled in winter.
Third, supplement nutrition.
Ye Mudan consumes a lot of nutrients during its growth, especially during flowering. If fertilizer cannot be replenished in time, the soil is barren and lacks nutrition, which will easily lead to leaf wilting. Before flowering, it is necessary to replenish fertilizer in time and apply phosphorus and potassium fertilizer frequently, so that branches and leaves and flowers can grow better. Pay attention to applying thin fertilizer, not too much at a time and not too high concentration.
Fourthly, proper temperature control.
The cold tolerance of celery leaf peony is limited, so it needs to be controlled after cooling in winter. If the temperature provided is too low, it is easy to frostbite the plant and the whole plant will wither. To move indoors in time, it is best to ensure that the temperature is above 5 degrees.
Qin is afraid of wet soil, so it should be cultivated in dry soil, but it should not be too dry, especially in the late growth stage. Too dry soil will make it dormant and affect the quality of flower heads.
