Breeding method:

1. Sowing: In early August, peony seeds will be harvested in time after they mature, and sowed immediately. If seeds are sown too late, they should not germinate in spring. Peony does not bloom until 5-6 years after sowing, so this method is generally only used when cultivating new varieties.

2. Plant division: Dig out the big peony plants that have grown for more than five years, put them in the shade for 2-3 days, divide them into 2-3 branched seedlings when the roots become soft, and plant them in the nursery.

3. Grafting: Cut soil buds or annual short branches from big peony, cut them into wedges of 2-3cm, embed them in peony roots with a length of 15-20cm, wrap them tightly with hemp skin, spread mud and plant them. Grafting time is 10 from the first ten days of September to the first ten days of 10, and grafted seedlings should be dug and planted well.
