In the fall, mineral phosphorus-potassium fertilizers should be used as a top dressing for peonies:
15-20 g of superphosphate, potassium sulfate, potassium magnesium;
potassium monophosphate - 45-50 grams;
phosphorus-potassium mixture - 35-40 grams.
Potassium and phosphorus can be used in different ways.
Method 1. Sprinkle dry on moist soil under the bush. Each plant needs 15-20 g of phosphorus and 10-15 g of potassium.
Method 2. Dissolve an identical amount of the substance in water and spill the bushes with the finished solution.
Scatter bone meal (200 grams per 1 m2) under the plants, and then embed it in the soil.

After the first frost, peonies need to be fed with limited fertilizers.
200 g of ash per bush. After pruning the bushes, powder the sections and trunk circle.
8-10 kg of humus or compost per bush. Spread it on the trunk circle evenly over the soil surface.
