How to conserve flowers in summer

Summer is hot and rainy, which is not only the peak season for the growth of some flowers, but also the dormant period for some flowers. In order to make flowers go through this stage smoothly, the management should be strengthened in the aspects of watering, shading, prevention and control of diseases and insect pests.

At the same time, in the high temperature season, in addition to jasmine, rose and other exuberant flowers, it is generally not suitable to apply fertilizer, especially the cuckoo that enters the semi-dormant period and the dormant bulbous flowers such as cyclamen and freesia.

Secondly, for some semi-overcast and negative flowers, avoid high temperature and direct sunlight in summer. Shading measures should be taken and water should be sprayed to cool down.

Even drought-tolerant plants such as cacti are at risk of being burned when the temperature exceeds 38 ℃.

In addition to daily watering, cuckoos should also spray water on the leaves and the ground to keep moisture and cool down.

But there are often heavy rains in summer. After the basin soil is stagnant, the nutrients are easy to be lost, so the basin should be tilted after rain to eliminate the stagnant water.

The muggy summer is also the season with high incidence of diseases and insect pests. It is necessary to remove the diseased branches and leaves in time, supplemented by drugs for prevention and treatment.

Such as monthly and summer prone to black spot disease and powdery mildew, the former with Bordeaux liquid, the latter with carbendazim, once a semimonthly spray.

Orchids are prone to anthracnose in plum rain and high temperature seasons. in addition to improving ventilation and light transmission, topiramate can be sprayed every 10 days when the disease occurs.
