Why can't plants be watered at high temperature in summer?

Hello! Why can't plants be watered under high temperature in summer? Because of the high temperature in summer, the transpiration of plants is also strong. If you water the flowers at this time, because of the large temperature difference between the water temperature and the soil temperature, it is easy to make the soil temperature in the flowerpot drop sharply, which will stimulate the root system of the plant, lead to the decrease of the water absorption capacity of the root system, and lead to the yellowing and burning of the upper leaves of the plant due to lack of water. Moreover, if you accidentally drop water on the leaves when watering the flowers, it is easy to burn the leaves after being irradiated by the sun, which will affect the appearance. Therefore, it is best not to water the flowers when the temperature is very high, but before 10 am and after 4 or 5 pm.

? Experience sharing: four kinds of flowers can not be watered and the key points of high temperature maintenance

In summer, the temperature is high, the water evaporates quickly, and the demand for water by flowers and plants at home is gradually increasing. Therefore, the work of watering becomes particularly important. If you accidentally water the wrong water, it will also have an impact on the health of flowers. Like the following four kinds of water, you can't water flowers in summer, which is extremely unfavorable to the growth of plants. ?

The following four kinds of water cannot be watered with 1, and it is forbidden to use raw fertilizer and thick fertilizer water:

Due to the high temperature in summer, the temperature in most parts of China is basically above 30 degrees. Many flowers will go into dormancy and semi-dormancy because they are not resistant to high temperature, and the demand for fertilizer and water is greatly reduced. If you pour some raw fertilizer and concentrated fertilizer on the flowers at this time, it will only increase the burden on the roots, cause fertilizer damage and burn the roots and seedlings, especially the immature raw fertilizer and water, which will not only stink easily, but also attract insects. It is also easy to "burn" flowers directly because of the large amount of heat generated by fermentation. Therefore, in summer, you must never use raw fertilizer and rich water to raise flowers, such as leftover milk, rice washing water, soybean water and peel water, which need to be fully fermented and diluted before use.

2. Half of the water can't be poured:

Watering flowers in summer, it is best to follow the principle of "seeing dry and seeing wet, not watering, watering thoroughly". Don't water the flowers for a long time. The so-called half-water refers to the behavior of watering half and stopping watering when the surface of the basin soil is wet. It is extremely harmful to water flowers with half water for a long time. On the one hand, it is easy to cause the basin soil to "wet on the top and dry on the bottom", which leads to the hardening of the basin soil; On the other hand, the roots of plants can't absorb water for a long time, and naturally they can't supply water to flowers normally, which affects the normal growth of plants. Even if they are watered frequently, flowers will still die. So when watering the flowers in summer, you must water them thoroughly at one time, and don't always "give up halfway".

3. The tap water just connected can't be poured:?

It is best not to water the flowers directly with tap water that has just been connected. On the one hand, tap water contains substances such as residual chlorine and bleaching powder, which is harmful to the health of flowers. Long-term use can easily lead to soil hardening and serious alkalization. On the other hand, the temperature of the tap water that has just been connected is relatively low, so it is easy to damage the root system of plants and make the flowers catch cold, so tap water must be put in the sun for a day or two before it can be used.

4. Medicinal fish water can't be used:?

If you raise fish at home, it is still good to use the water from fish farming to water the flowers. Fish culture water contains fish excreta, which is a natural organic fertilizer and can provide certain nutrition for the growth of flowers and promote their growth and flowering. However, if drugs or salt are added to the fish tank, it can't be used for flowers, which is easy to cause certain damage to the health of flowers and breed germs.

? Key points of high temperature maintenance

In summer, it is the primary task to maintain plants at high temperature and replenish water in time. Secondly, try to create a cool environment. You can put it on the balcony or windowsill with curtains at home, or add a sunshade net to outdoor plants, which can resist the scorching sun without affecting the light and not afraid of sunburn. When placing plants indoors, avoid directly facing the air outlet of the air conditioner. In summer, every household inevitably depends on air conditioning to cool down, but drastic temperature changes will harm plants, and foliage plants are prone to dry leaves and scorched edges. Flowers should be kept away from air conditioning vents, or moved to window sills to allow plants to naturally ventilate.
