It is difficult to grow flowers in rainy days, and the yellow leaves are black and rotten. Keep in mind the four formulas, safety is "rainy season"

It rains again in summer, especially in the south, and sometimes the continuous rainy season is very annoying.

The weather is changeable, so people can hide indoors to cope.

However, if the flowers and plants raised at home often encounter rainy weather, they are particularly prone to various problems, the most common of which are various bacterial infections and pests and diseases.

Friends who have many flowers at home often have headaches when it rains, but they still have to find ways to deal with them.

By remembering these formulas, we can avoid the situation of flowers and plants dying in rainy days.

If you are not careful, you may only have empty flowerpots left.

So what should we pay attention to when it rains?

First, if it rains continuously, it is necessary to spray chemicals.

If it encounters continuous rainy weather and the air humidity is relatively high, it is particularly prone to bacterial infection. Be sure to prepare some bactericidal drugs.

If you plant flowers outdoors, the pot soil is often wet in the rain for a long time, which is easy to deposit.

The air in the flowerpot is squeezed away by water, which makes the roots stuffy, rotten and rotten.

Therefore, it is necessary to dry the soil in time and spray it with medicine to prevent bacterial infection and rotten roots.

If you plant flowers indoors, it is usually humid indoors.

Flowers and plants are also easily infected by some germs, especially friends who raise Chinese roses, which are prone to powdery mildew, black spot and leaf spot, so spray them before it rains.

If you hear the weather forecast, you should spray bactericidal drugs such as carbendazim or chlorothalonil the day before to prevent bacterial infection in advance.

Spray medicine after getting wet to prevent bacterial infection, especially rose flower pots, which are really annoying before and after the rain.

However, in order to prevent the fading of black leaves, powdery mildew and leaf spot of Chinese rose.

Spraying medicine in the rain is essential. For other flowers and plants cultivated in the open air, it is best to spray some bactericidal drugs to prevent these situations.

Second, apply fertilizer after getting wet.

Some people think that when it rains, you can take out the flowers and plants raised at home and take a bath, which can supplement nutrition and moisten plants.

In fact, it is also very important to fertilize flowers and plants at this time. Don't just hydrate them.

Because the rain falls into the flowerpot for a long time, the excess nutrients in the flowerpot will be infiltrated, and the nutrients in the soil will gradually decrease, only adding water.

When the weather is clear, they get enough water and consume more nutrients, so they will grow, and then they can fertilize.

Give it some multi-element fertilizers, or potassium dihydrogen phosphate and other fertilizers to promote plant growth.

They can absorb nutrients quickly and grow rapidly.

If you only get wet in the rain and don't fertilize, it is possible that nutrients can't keep up and affect the growth rate.

Third, don't water in rainy days.

If you plant flowers indoors and outdoors, don't water them before it rains. If flowers and plants are not particularly short of water, try not to water them.

Because the air humidity is relatively high at this time, the air is also relatively humid after the rain, and the increase in humidity is easy to cause leaf rot.

Moreover, it is easy to recruit some cases such as white spot disease and black rot. If the basin soil is kept moist, it is easy to have rotten roots.

So if you hear the weather forecast that it will rain, don't water it a day or two in advance, just wait until it rains or after it rains.

Fourth, shade after sunny days.

If it is cloudy or rainy, it will last for more than two or three days, sometimes even for a week or so.

At this time, the plants have not seen the light for a long time. If the sun shines suddenly on a sunny day, the leaves are easy to get sunburned.

Because plants have not seen the light for a long time, if they have been in a dark environment, it is easy to burn their leaves when they suddenly see the light.

Leaves will wilt and get sunburned, which will affect the ornamental value of plants.

Leaves with slight withering and severe sunburn, so even after cloudy weather, plants should be properly shaded or taken to a semi-shady place for maintenance to maintain their vigorous growth.

In rainy weather, we should also pay attention to some plants that can't touch water, such as Clivia, a leafy and deep plant.

Don't get wet in summer. When rain falls on leaves, it won't evaporate and it is easy to produce rotten leaves. Then this Clivia tree is finished.

Moreover, there are many dormant plants, and plants that are afraid of heat can't get wet for a long time, such as succulents, geraniums, longevity flowers, crab claw orchids and so on. I prefer flowers and plants in the cold season.

Don't get wet when it rains, otherwise there will be too much water in the flowerpot, and their roots will not work, and rotten roots will appear in the flowerpot with accumulated water.

Then, these plants can only empty their flowerpots in autumn.

Although rain in summer is good for plants, there are still several situations that need attention in order to prevent flowers and plants from getting wet and sunburned.
