When to harvest peony seeds
Today, I will introduce to you when to harvest peony seeds and the skills of planting peony seeds, as well as related experience in flower planting. Below, the editor will answer your questions in detail.
I. Propagation Methods
1. Sowing
Peony 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 cultivating new varieties.
2. Division
Dig out the large peony plants that have been growing for more than five years, place them in a shaded area to dry for 2-3 days, and then divide them into small plants of 2-3 branches when the roots become soft, and plant them in the nursery.
3. Grafting
Clip the soil sprouts or one-year-old short branches from large peony plants, cut the lower 2-3 cm into a wedge shape, and insert them into 15-20 cm long peony roots. Tie them tightly with bast and apply mud before planting. The grafting time is from early September to early October. The grafting seedlings should be planted in trenches with a plant spacing of 10-15 cm and a row spacing of 30-40 cm. After planting, heap up soil ridges so that the scion does not expose above the soil.
II. Maintenance Management
1. Fertilization
Fertilize at least three times a year. The first time is before flowering to promote blooming; the second time is half a month after flowering to supplement the nutrients consumed by flowering; the third time is before overwintering to apply winter fertilizer. Use ripe cake fertilizer as the main fertilizer. The appropriate amount of fertilizer is 0.5-1 kg per plant each time, and chemical compound fertilizer can also be mixed.
2. Watering
Peonies are relatively drought-resistant, but watering is still needed during dry seasons to keep the soil moist. Accumulated water should be drained after rain.
3. Disease and Pest Control
Common diseases of peonies include brown spot. The control method is to start spraying Bordeaux mixture or thiophanate-methyl solution every half month 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 cottony scale insect, which attaches to the branches and leaves in white during the summer and autumn seasons. It 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 white grub. The control method is to wash the roots 20-30 cm deep with a 50% phoxim emulsion at a concentration of 1000-1500 times, with an appropriate amount of 0.25 kg per mu.
