Peony growth not done after harvest of flowers

After flowering fertilization needs to be aimed on the vegetative growth of the plant, the leaves need to grow and fully mature. The leaves that are forming the plants now will be the basis of the flower production the following year. The formation of the flowers will be in July and August. Take soil samples/leave samples regularly and in fixed time periods, so that you will get a better view of the needs of the plant.

Normal applications of fertilization kg/ha for peonies on a year basis:
  • (at normal soil values)N-needs, 150 kg/ha
  • Phosphate, kg P2O5, 100 kg/ha
  • Kali, kg K2O, 225 kg/ha
  • Magnesium, kg MgO, 100 kg/ha
After flowering, fertilize for flower bud formation next season:
  • Calcium apply halve (for example Patent kali)
  • Nitrogen minimal 50 kg
  • Magnesium (bitter salt)
Be alert that enough water will be available for the plant to take up the fertilizers. Drought in this period will damage the flower harvest for the next year.

An active soil life is very important; moist soil and a correct organic matter level are very important to improve the taking of the above mentioned fertilizers.
