Peony has nine colors such as red, purple, pink, blue, white, green, yellow, black and multicolor and six flower types.
In addition to common varieties such as Luoyang Red and Hu Hong, mung bean green, yellow, blue Zhan Lu, Black Qinglongwo, Guanshi Moyu, Red Sun and Kao are all rare and rare varieties.
Peony can be cultivated in the open field or potted for viewing. The best planting season is September -65438+ 10. Potted peony should choose varieties with strong adaptability, early flowering and good flower pattern, such as Luoyanghong, Hong Hu and Zhao Fen. Plants should choose peony as rootstock, 3-4-year-old peony or 3-5 branch seedlings.
When potted, the bottom of the basin can be covered with 3-5 cm thick coarse sand or pebbles to facilitate drainage. Potted soil should be a mixture of yellow sand and cake fertilizer, or a culture soil mixed with fully decomposed manure, garden soil and coarse sand at the ratio of1:1. Filling makes the roots stretch, not curl; After covering the soil, it should be compacted by hand, so that the roots are in close contact with the soil and easy to survive. After the pot is put on, water it once and put it in the shade to slow down the seedlings. After it is transferred to normal management, it can be placed in a sunny place to ensure sufficient sunshine. Always loosen the soil during the growing period and apply compound fertilizer every half a month or so. Peony in the new pot should not be fertilized, especially avoid applying thick fertilizer, otherwise the fleshy roots will rot and die. After half a year, you can gradually apply some thin fertilizer, such as decomposed chicken manure water or bean water, with a ratio of fertilizer to water of 20%-30%. The peony in the new pot may not bloom well in the first year, but it can bloom every year after 1-2 years. Peony blooms in the middle and late April of a year, and liquid fertilizer can be applied 1-2 times before flowering; Topdressing liquid fertilizer 1-2 times half a month after flowering; In dog days, sesame sauce residue (about 40-50g per pot) can be applied with 1 times dry fertilizer, which is beneficial to flower bud differentiation.
Peony is a fleshy root, slightly resistant to drought and most afraid of water accumulation. Therefore, proper watering is the key to the success or failure of potted peony. Peony leaving the house in early spring should be watered and fertilized first, then watered, and then loosened after the water is slightly dry. In the future, it is necessary to water the soil timely and properly according to the weather and soil conditions, and keep the soil moist frequently, which is beneficial to the growth and flowering of peony. Reasonable watering should be dry but not wet, and should not be watered to prevent water accumulation, so as to avoid rotten roots and fallen leaves.
When peony blossoms, it can be covered in the shed or temporarily placed indoors to avoid direct sunlight and prolong the flowering period. The terminal bud of the main branch is a leaf bud, so it should be picked to avoid unnecessary growth and affect flowering. In order to make peony bloom brightly, it can be sprayed on leaves with 0.5%- 1% dihydrogen phosphate solution for 2-3 times during flowering. After the peony flower withers, it should be pruned once, and the residual flowers and pedicels should be cut off in time to prevent fruiting, and the 1-2 lateral buds in the stem should be reserved to make the plant grow vigorously and ensure the next year's flowering.
Peony is cold-resistant, but in cold areas such as North China and around beginning of winter, it should be moved indoors and placed in the sunny place indoors, and the room temperature can be kept at about 0 degrees. It is not advisable to leave the house early in the following year, and it is necessary to leave the house before and after Qingming. In the not-too-cold area, the flowerpot can be buried in the soil in the hidden wind, so that the surface of the flowerpot is flush with the ground, thus maintaining the humidity and temperature of the flowerpot soil and ensuring the peony to survive the winter safely. After the peony blooms in the next spring, the peony is dug out of the ground with a flowerpot for normal management.
