How to plant peonies, peony cultivation techniques and management.

How to plant peoniesA brief introduction to the main text: This article explains the methods of planting peonies, the cultivation techniques, and management of green plants and flowers. Let's get to know more about it together.I. Propagation Methods1. SowingPeony seeds should be harvested in early August when they are mature and sown immediately. Sowing too late is not conducive to germination in the spring. It takes 5-6 years for peonies to bloom after sowing, so this method is generally only used for breeding new varieties.2. DivisionDig out large peony plants that have been growing for more than five years, place them in a shady place for 2-3 days to soften the roots, and then divide them into small plants of 2-3 branches each to be planted in the nursery.3. GraftingCut the soil sprouts or one-year-old short branches from large peony plants, shape them into a wedge 2-3 cm long, and graft them onto 15-20 cm long peony roots. Tie them tightly with hemp skin, apply mud, and plant them. The grafting time is from early September to early October. The grafting seedlings should be planted in trenches with a spacing of 10-15 cm between plants and 30-40 cm between rows. After planting, cover with soil ridges so that the scion does not expose to the soil.II. Maintenance Management1. FertilizationFertilize at least three times a year. The first application is before flowering to promote blooming; the second is half a month after flowering to replenish the nutrients consumed by flowering; and the third is before winter. Use ripe cake fertilizer as the main fertilizer. The amount should be 0.5-1 kilogram per plant each time, and it can also be mixed with chemical compound fertilizer.2. WateringPeonies are drought-tolerant but still require watering during dry seasons to keep the soil moist. Accumulated water should be drained after rain.3. Disease and Pest ControlCommon diseases of peonies include brown spot. The control method is to spray Bordeaux mixture or carbendazim solution every half month starting after flowering each year. Before winter, cut and burn the diseased leaves in time, and spray lime sulfur solution before spring germination.The main pest of peonies is the吹绵介壳虫 (unknown translation for "吹绵介壳虫"), which附着 (attaches) on the branches and leaves during the summer and autumn seasons. This can be controlled by spraying 500 times the concentration of fluoroacetamide or 1000 times the concentration of dimethoate solution, or by applying lime sulfur solution to the branches after winter.The main underground pest is the grub. The control method is to wash the roots 20-30 cm deep with a 50% phoxim emulsifiable oil solution diluted 1000-1500 times, with an appropriate amount of 0.25 kilograms per mu.The above information on how to plant peonies and the cultivation techniques and management of peony flowers introduced by the Green Plant Enthusiast website is complete.
