Cooling and shading

1. Add shading net

In summer, the temperature basically exceeds 30 ℃, while the suitable growth temperature of many flowers is about 20 ℃. If the flowers are not cooled, it is easy to cause the flowers to be dried to death. If it is raised in the open balcony or courtyard, it is best to add a shading net. If it is on the indoor balcony, you can add a shading curtain when it is hot at noon

2 blowing air conditioner or fan

The temperature continues to rise at noon in summer. In order to avoid damage to the flowers, you can move the flowers indoors and cool them with air conditioner or fan

3. Water spray on blade surface

In addition to the above two methods, the most commonly used one is to spray water on the leaf surface to reduce the temperature. When using this method, pay attention to make the water sprayed from the watering can appear in the state of water mist. If it is water droplets, it is easy to remain on the leaves and burn the leaves

Watering

1. Watering in the morning and evening

The temperature is high at noon in summer. If you choose to water at noon, on the one hand, the transpiration of leaves will become larger and the water loss will be faster. On the other hand, if the water accidentally infects the leaves, it is easy to burn the leaves

2 do not use fresh water

In hot weather in summer, the temperature of the soil surface will rise. At this time, if you water the flowers with the water just connected from the water pipe, it is easy to cause the temperature of the pot soil to drop suddenly, which will stimulate the root system. In addition to not absorbing water, it may also cause the flowers to stop growing. Therefore, before watering, it is best to dry the water for a period of time and water the flowers when the water temperature is about the same as the room temperature

3. Water the flowers with many leaves

Many flowers with many leaves, such as some large green plants, have a very large evaporation capacity. In order to meet the normal growth needs, we have to water more in summer, about 1 / 3 more than usual

Ventilation

1 increase air humidity

The temperature is high in summer. Many flower friends like to put flowers in air-conditioned rooms. However, the air-conditioned rooms are relatively dry. Many flowers are placed indoors, which can not reach high air humidity, which is easy to cause the dry tip of yellow leaves. In order to increase air humidity, it is best to open a humidifier indoors, place a basin of water in the room, or often wipe the leaves of flowers with a wet cloth

2 move outdoors in the morning and evening

Blowing air conditioner or fan indoors can reduce the temperature of flowers, but correspondingly, if the windows are closed for a long time and the indoor air is not circulating, it is easy to cause black rot of flowers. Therefore, we should often open windows for ventilation. When the temperature drops in the morning and evening, we can move the flowers to the balcony

3 do not blow directly into the air conditioner

The wind blown by the air conditioner is relatively dry. If the flowers are placed where the air conditioner can blow directly in order to reduce the temperature, it is easy to cause the leaves of the flowers to wilt and turn yellow, or even anxious< span>
