How long after the sun sets is more suitable for watering the flowers in the pots on the balcony

It should be done after sunset or one hour after no direct sunlight on the plant body.

The best time to water in summer is before sunrise or after sunrise when the vegetation has not yet been heated. If watering is done in the afternoon, it should be done one hour after sunset or after no direct sunlight on the plant bodies. Avoid watering in the middle of the day in the heat.

Because, under the scorching sun, the soil temperature is high, the evaporation is large, the roots must work normally to supply the plant with sufficient water, such as the sudden use of cold water to water the flowers, the root system and soil temperature drop, the root activity is weakened, the water absorption slows down, the result is in short supply, the occurrence of "physiological drought", the upper leaves wilt or scorch. Therefore, when it is necessary to water in hot weather, the water must be put in the pool or tank first, so that the water temperature is not too low, and then watered. The amount of water to water flowers, in general, should master the principle of "seeing dry and wet", that is, not dry, not watering, watering thoroughly.

However, the amount of watering depends on the type of flower, its habits, its growth stage and the soil. For those flowers native to humid areas, such as palm bamboo, mast, palm, rhododendron, etc., you can properly water more; And cacti, sedum, and some fleshy root flowers, should be watered less to "rather dry than wet"; Drought-tolerant flowers, such as osmanthus, pomegranate, five-color plum, etc., should be "more dry and less wet"; Flowers that like moist soil, such as calla lily, monstera, etc., should be "rather wet than dry"; Neutral flowers, such as Yueji, white orchid, smile, etc., should be "wet and dry". Herbaceous flowers are watered more than woody flowers; Dormant or semi-dormant flowers, such as cyclamen, upside-down admiralty, geranium, begonia, etc., should be watered less or stop watering to keep the pot slightly moist; Do not water too much when flowering or fruiting flowers, such as pomegranate and fragrant balls, otherwise it is easy to fall flowers and fruits.

In addition, the summers are hot and rainy. Some potted flowers and trees are best watered with cool water once when the weather is sunny after heavy rain, which can adjust the temperature of the surface soil and air and reduce the adverse effects of dampness and heat on flowers; If the flower wilts due to extreme lack of water, it should be placed in a cool and humid place, first watered a small amount of water, and then gradually increase the amount of water to make it slowly recover.

According to the experience of the farmer's uncle, the crops can be watered before and after the sun goes down. If it's summer, it's best to water it after the sun goes down and it's not too hot, and if it's cold, it doesn't matter, it's okay after 4 p.m.

The key is to water the pot in time when the soil temperature drops close to the watering temperature.

It is okay to water early and late, but it is recommended to water late, to protect the roots of the plant, don't water it several times a day, follow the principle of dry and wet, and water it until the soil of the pot is dry and watered until the basin seeps. That's for the best.

Wish: Flourishing.

In the morning, the sun roasts the soil during the day, and it is cool after a night, and it is better to water in the morning, which is the time when the plant grows most vigorously, and absorbs more water.

Once every 3 days It is best to pour it around 8 p.m.

It's easy to do with sunlight, plus ventilation, basically you can raise whatever you like. Just grasp the characteristics of each plant. For example, dry orchids and wet chrysanthemums, orchids like dry, and chrysanthemums like moisture.

African Jasmine This sunshine, good!

When you buy a flower pot, you will have a bottom tray to prevent water seepage.

Solution: The third floor of a handful of Hu is about (10-12) m in height.

Gravitational acceleration g, take 10(m s 2).

Then, h=v0t+1 brother regret 2at 2=0*t+1 2*10*t 2 then, t= (h 5) envy = approximately equal to)

v=vo+at=0+10*

The soil in the pot is not good, and it will ...... musty smell when watered

Have you changed the soil? In this case, it should be the smell of the soil, and if you change the soil, it will be gone.

Hope. Thank you.

It doesn't matter how thick the soil is, the key is whether your flowers are frost resistant. If you raise the moon season or something, you basically can't freeze to death, and if you raise orchids, you won't freeze to death if you don't need to raise them. So the key is not how thick the soil is, but what kind of flowers you are going to raise.
