How to fertilize peony flowers

Before planting peony, base fertilizer is very important, such as manure, cake fertilizer and compost.

Pre-flowering fertilizer is generally applied in the first half of 10. The fertilizer applied at this time has a great influence on the flowering of peony this year. Many experienced gardeners call it "promoting flower fertilizer". The fertilizer can be mainly decomposed cake fertilizer or phosphate fertilizer.

Post-flowering fertilizer is generally applied half a month after peony blossoms. Fertilization can increase the number of flowers at this time. Especially for the next year's flowering, there is a direct connection, such as the number, color and size of flowers. The fertilizer can be mainly decomposed cake fertilizer or compound fertilizer.

Overwintering fertilizer should be applied before winter. It is usually accompanied by watering. This kind of fertilization can also raise the soil temperature, which is of great help to peony in winter. Fertilizer is still mainly organic fertilizer.
