The basin soil requirement of peony flower is relatively simple. Generally, the sand soil with good drainage, fertility and looseness can be selected. The soil mixing methods are: rotten leaf soil, garden soil and fine river sand.
Before planting, use it after disinfecting with carbendazim or thiophanate methyl solution.
Proper watering is the key to cultivating peony. In spring, after moving out of the room, water once, loosen the soil after watering, and then keep the soil moist.
According to the size of the pot soil, the frequency of watering should be increased after the flowerpot leaves the room. In rainy summer, the water in the basin should be poured out in time to avoid root rot.
Peony is a fertilizer loving plant. If you want to make peony flowers big and colorful, avoid the phenomenon of flowering next year, you should pay attention to the timing of fertilization. It is forbidden to apply fertilizer to the newly planted peony within half a year, and start to apply fertilizer half a year later.
Generally, it needs to be applied three times a year. For the first time, the fertilizer was applied when the soil was thawed and the leaves were stretched out; for the second time, the fertilizer was applied within half a month after the flower withered, which promoted the plant recovery and flower bud differentiation. The third time is winter fertilizer, which is applied before winter to promote spring growth.
In order to promote the growth and beauty of peony, it is necessary to trim it in time. The pruning of peony can be divided into winter and spring and summer.
In spring, we should choose to keep branches and buds, wipe off the redundant branches and buds, cut off the branches that grow thin and weak, infected by diseases and insect pests, and grow in vain, so as to ensure the beautiful plant type, ventilation and light transmission.
Cut off the flowers after they fall in summer. At the end of autumn, cut off the diseased branches, dead branches and long branches.
Sufficient light is very beneficial to the growth of peony, but it can not be exposed to the sun for a long time.
The suitable growth temperature was 15 ~ 25 ℃, and the plants were dormant above 25 ℃. During the period before flowering, the plant should be ventilated in time to avoid over high temperature and affecting the growth of the plant.
