When flowering, the temperature can be appropriately reduced, the humidity can be increased, and sunburn can be avoided, thus prolonging the viewing period. Too short sunshine time in spring, such as 8-9 hours, will lead to delayed bud development, accelerated leaf growth, poor flowering, or even failure to bloom; In spring and summer, if the sun is strong, shading can be appropriate, and never over-shade, otherwise the plants will grow white, grow weak, and cannot bloom or bloom sparsely. After the first frost, cut off the dead leaves to prevent the breeding of pests and diseases;
It needs pruning three times a year. The first time was in early March, after the second flower withered, if you don't plan to sow and propagate, you should cut off the pedicel at any time to avoid sowing and consuming nutrients. For the third time, from the end of June 65438+ 10 to the beginning of June 165438+ 10, all kinds of pests and diseases, dead branches, overlapping branches, inward branches, cross branches and long branches were pruned. For the development space of bare branches, appropriate length can be reserved and shortened to fill. For weak branches and aged branches, they can be cut off to stimulate the germination of dominant buds and recessive buds. Pruning is to keep the tree in balance and grow vigorously. In autumn and winter, due to the spread of diseases through leaves, the residual leaves of Paeonia lactiflora were removed.
Because peony is cold-resistant, it doesn't need to be moved indoors, just put it in a place where light is scattered. But if it is in the northeast of Inner Mongolia, the situation is different, because the local temperature is too low. In this case, we will protect it by burying it, so that we can bury the roots with completely wet soil at a certain height, so that it will not freeze.
Paeonia lactiflora is cold-tolerant and drought-tolerant. It likes the sunshine and cool climate in summer. Potted peony is easy to burn leaves in the hot summer sun, so attention should be paid to shading in summer.
Paeonia lactiflora is drought-tolerant and does not need to be watered frequently. However, the water demand is the largest before and after flowering, and the watering times can be appropriately increased when the weather is relatively dry in spring. Because peony is a fleshy root, we must pay attention to the frequency of watering, and don't water it too much, otherwise it will cause root rot and lead to plant death.
Topdressing is usually applied three times a year. The first time is when new buds are quickly drawn out in spring, and the other two times when leaf buds are elongated, quick-acting fertilizer is mainly applied, also called flower-promoting fertilizer. Pay attention to the amount of fat can not be too much, too much will cause root burns.
