Management of potted flowers, trees and plums in rainy season

Plum yellow ripe plum rain season, the air humidity, suitable for a variety of mold reproduction, so it is also known as the mildew and rain period. Meiyu often brings many adverse effects to the growth of potted flowers and trees. therefore, we must do the following work well in order to make potted flowers and trees steadily survive the mildew and rain period.

1. Waterlogging refreshing water

In the rainy season, open-field potted plants are vulnerable to waterlogging, and because of the high air humidity, the amount of water and times of watering should be reduced. At the same time, potted flowers and trees should often loosen the topsoil and use wooden poles to poke holes along the basin wall to the bottom of the basin to facilitate drainage and ventilation and prevent the root system from suffocating to death due to anoxia.

In addition, before the heavy rain, you can also lie on the side of the basin, which can not only prevent stagnant water, but also avoid nutrient loss. For succulent roots and cactus plants, should be moved to shelter under the rain shed, or covered with a film cover to protect against rain.

2. Pick the heart and hit the top

For woody potted flowers that bloom in winter and spring, such as camellia, spring, etc., the focus is to pick the heart and hit the top, in order to control the distribution of nutrition and promote reproductive growth. For the flowers and trees that are still in the vegetative growth stage in summer and autumn, such as Fusang, hibiscus, etc., measures such as picking the heart and topping, hanging and twisting branches can be taken to promote branching, weaken the advantage of apical growth, control the crazy growth of plants and make their lateral growth. Lay the foundation for flower bud differentiation and bud expansion.

3. Strict control of fertilizer and water

Branches are easy to grow in Meiyu season, in addition to picking the heart to control the early vegetative growth, it is also necessary to strictly control the supply of fertilizer, especially the application of nitrogen fertilizer.

4. Prevent falling flowers and fruits

Potted trees that blossom and bear fruit in summer, such as pomegranate, sprout flower buds on current year's shoots, expand into buds and blossom. When the young fruit is formed after flowering, in addition to spraying strong bud fruit setting agent on the leaf surface, we should also control the topdressing of nitrogen fertilizer and pay attention to the stagnant water in the basin, so as to prevent bud and fruit drop, and strengthen the supply of phosphorus and potassium fertilizer. As for potted oranges, the late spring shoots must be cut short, the new buds should be wiped out in time, and after the first physiological fruit drop, 2% boric acid water and potassium dihydrogen phosphate should be sprayed on the leaves to prevent late fruit drop. During this period, peaches, pears and other flowers and trees that have set fruit should make use of the favorable period of Meiyu to prune in early summer and adjust the ratio of fruit and leaf, which is beneficial to the growth of young fruit and the improvement of fruit quality.

5. Control of diseases and insect pests

First of all, it is necessary to carry out moderate light cutting of flowers and trees, followed by enlarging the distance between pots to facilitate ventilation, and at the same time, spraying to control diseases and insect pests, once a week, for a total of 3 to 4 times, so that diseases and pests can be eliminated at the same time.
