In the plum rain season, the rain is continuous. No matter in the field or in the pot, the water should be drained in time to prevent the root of the plant from suffocating and leading to the yellow root of the rotten leaf. Once there is water in the flowerpot, you can use long and thin hard things such as bamboo sticks to stick into the flowerpot several times to make sure that you can steal it, but not to the root. Here's a small way: if there is water in the flowerpot, you can use bamboo sticks and other hard things to penetrate the bottom of the flowerpot to increase the soil permeability. Do not hurt the root.
Fertilizer should not be applied too much, especially not to human manure, chicken manure, milk, soymilk, fish offal and fertilizer. For example, if the concentration of urea is not better than too high, it will burn the root, causing the leaves and flowers to wither and blacken rapidly. Because of the humid air and the growth of microorganisms in the plum rain season, if the fertilizer is applied randomly at this time, the roots of plants will rot due to too many microorganisms.
In case of diseases and insect pests, we should distinguish different conditions and apply drugs according to the symptoms. Even the rainy days are the multiple periods of diseases and insect pests, such as leaf spot, root rot, spider, etc., which requires us to take the drugs according to the symptoms and not to use them indiscriminately. If there are dead branches and leaves, they should be removed in time to prevent rot and breeding of pests and pathogens.
After a few rainy days, because the branches of the flowers are relatively tender, it is necessary to avoid sudden direct sunshine, so as not to burn the tender leaves and flower buds. In addition, shade and ventilation should be done well for negative plants. The potted flowers that are placed outdoors can be moved to the ventilation place for shelter from rain; if they are not easy to move, the bottom of the potted plants can be put up to remove the ponding pan, create drainage and ventilation conditions, and avoid direct exposure to the sun after rain.
Such weather is not only uncomfortable, but also a season of many problems for flowers and grass. So, do you need to water the plants in the rainy season? In the rainy season, the overall humidity is relatively high, and the soil will be easier to moisturize than usual. Even if flowers and plants are raised in rainy days, they need to be watered in time. Pay attention to control the frequency of root watering (except for succulent, cactus, aloe and other drought resistant plants). See that the basin soil is dry and then watered, and the leaf surface of the plant needs to be wiped properly to keep the plant breathing smoothly. Do not have ponding. After watering, strengthen ventilation to make it natural and dry.
The following maintenance points shall be paid attention to during the plum rain season.
Strengthen the ventilation to prevent the plants from getting sick. Spray the potted flowers once a week with insecticides and fungicides for 3-4 times in a row.
Loosen soil frequently to prevent soil from hardening.
Don't rain potted flowers often to avoid nutrient loss.
Heightening the flowerpot is conducive to drainage and also can prevent the basin soil from ponding.
In case of fallen leaves and rotten roots, the potted flowers shall be moved to a cool and ventilated place, and in case of serious situation, the potted flowers shall be replaced in time.
For large potted plants, the transpiration of leaves is reduced due to the high air humidity, so the watering times and amount should be reduced to prevent the branches from growing in vain.
Flowers that need sunshade should be put under the shade to prevent the sun from burning the leaves.
For large potted plants, adjust the proportion of flowers and leaves to prevent flowers and trees from falling. In order to control the vegetative growth, the vegetative branches should be cut short, the new buds should be wiped out, and potassium dihydrogen phosphate should be sprayed on the leaves to ensure the normal growth of flowers and fruits.
