What to do after the peony flowers fade

Strengthen water and fertilizer maintenance

Peony itself has poor drought resistance. After flowering, it is the peak growth season for peony and needs more water, so watering should be increased. Pay attention to two points when watering: first, the amount should be appropriate and not too much, and water should not accumulate. When watering, the soil must not be wet enough to avoid affecting the growth of the roots. The second is to loosen the soil in time 5 days after watering. This method can enhance the water retention capacity of the soil, reduce the number of watering, and is also very beneficial to the growth of the plants.

Peony likes fertilizer very much. Adequate fertilizer can ensure vigorous growth of the plant and enhance its disease resistance. Because peony consumes a lot of nutrients when it blooms, it is necessary to apply fertilizer in time after flowering. You can choose composted animal manure or sesame paste residue as fertilizer. When applying fertilizer, you can use the method of hole application or spraying fertilizer and water. Be sure to water thoroughly after fertilizing.

Timely pruning

Although peony is a herbaceous flower and does not have strong old roots or branches, pruning after flowering is equally important. First, remove the withered flowers in time to prevent excessive nutrient consumption due to fruiting, which will affect flowering next year. In addition, the overly dense branches should be thinned out to enhance light transmittance and provide sufficient space for their growth. The general principle is: the branches should not be too dense, the leaves should not overlap, the light transmittance of all parts of the plant should be guaranteed, the branches should be healthy, and there should be no diseased or insect-infested branches.

Pest control

After the peony flowers bloom, it will be summer. The hot and humid environment is the peak season for diseases and insect pests. This period is sometimes the peak growth season for peonies, and timely prevention and control of diseases and pests can ensure the healthy growth of peonies. At this time, prevention of diseases and insect pests should be the main focus, and fungicides should be sprayed once every 10 days. If diseases and insect pests occur, the dosage can be increased or the corresponding agent can be replaced.
