After the seeds of Paeonia lactiflora are ripe, they need to be picked and sowed in the soil. The survival rate of autumn sowing is high, while spring sowing is not easy to germinate.Soak the seeds in warm water for a day before sowing to promote rooting.Prepare loose and fertile soil, scatter seeds on the surface of the soil, water them with appropriate amount of water, and cover them with plastic film until the next spring.
Paeonia lactiflora is propagated by ramets.The time of division is usually in autumn, if the time is too early, it will easily lead to autumn growth of plants, affecting the growth of the second year, too late will also affect development.Before dividing, the plant needs to be taken out of the pot first, taking care not to hurt the root, and then 3-5 sub-plants are separated, the sub-plants need to bring 2-3 buds, and the separated sub-plants can be directly planted in the soil.
Cutting is usually carried out in mid-July, cutting branches 10-15 cm long as cuttings, with two nodes on the top, and compound leaves on the top.Dip the bottom of the cuttings with indoleacetic acid to promote rooting.Prepare loose and fertile soil, insert cuttings about 5 centimeters, then water thoroughly, keep the soil moist, usually 20-30 days will take root.
Peony layering needs to select a healthy plant, find a branch without pests and diseases from the top, and then girdle it, taking care not to break the branch.Wrap the girdling area with wet soil and wrap it with plastic tape, which can prevent the soil from falling off and also moisturize it.After rooting, they can be separated and planted.
