Prunus mume is one of the four gentlemen in China. It has been cultivated for more than 3000 years in China. It originated in the south of China and was later introduced to Korea and Japan. It has important ornamental and medicinal value. Many types are not only cultivated in the open field for ornamental purposes, but also can be used as potted flowers. Many people think that plum blossom has a strong ability of cold tolerance, thus ignoring the preparation before winter, leading to poor plum state after winter. So, what kind of maintenance should be done for plum blossom before winter? Let's go and have a look!
From early September to late November, with the assimilation of leaves and the backflow accumulation of nutrients absorbed by roots, the root growth climax. At this time, it is necessary to create good conditions for root growth and nutrient absorption, such as loosening soil frequently, avoiding excessive drying or wetting of basin soil, and properly applying organic fertilizer, etc., which is beneficial to pot culture The bud and blossom of plum blossom.
In autumn, the diseases and insect pests of potted plum blossom are relatively reduced. In order to reduce the stimulation of spraying pesticides on leaves, the application concentration should be small, and the spraying frequency should not be too frequent. In this way, the phenomenon of falling leaves and buds can be avoided. Strong wind is also one of the factors causing the leaves. In case of strong wind, the pot end can be put to the wind shelter and sunny place. The following are the specific maintenance methods:
1、 Basin soil should not be too dry or too wet. After autumn, potted Prunus mume is very sensitive to water, and the soil is too wet, which can easily cause premature yellow leaves, fallen leaves, and even retting roots and die. If the soil is too dry for a long time, it is easy to cause fallen leaves and affect the bud and flower. Therefore, watering should see that it is dry to see wet, not dry do not water, pouring is pouring thoroughly. After autumn cooling, the amount of watering should be gradually reduced to facilitate the enrichment of branches.
2、 Strengthen the management of fertilizer and water. After autumn, organic fertilizer solution should be applied once every 7-10 days, mainly phosphate fertilizer. At the same time, 0.1% - 0.2% potassium dichloride phosphate solution should be applied once or twice, and the young shoots germinating in autumn should be cut off. Because the young shoots can not mature in winter, the nutrients are consumed in vain, so timely pruning can achieve the purpose of accelerating buds.
3、 Trim and shape properly. In order to make the potted plum blossom blossom more and more beautiful, we should take sparse branches and shaping. In autumn, the short branches should be 10 cm short, and the long branches should be kept 5-6 buds short, so the branches should be sparse, the branches should be beautiful and the flowers would be more and more big. After pruning and shaping, the next year, the flowers will be numerous, big and colorful.
4、 Appropriate cold prevention measures. If you are a flower friend in the south, you don't have to worry about it. It is said that the flower friends in the north have a certain cold resistance, but it is limited to the adult plum blossom. If it is a seedling, it needs to do some necessary cold prevention measures. If it is potted, it can be put on the indoor balcony for winter. If it is planted in the open field, the root should be covered with straw and wrapped with cotton cloth The trunk of a tree.
