Why do flowers need shade in summer and how should shade be provided

First, shading flowers is mainly to protect them from rain and help lower the temperature. All flowers grown on a large scale should be produced in facilities, avoiding open-field cultivation as much as possible.

The high temperatures, intense sun and showers of summer can easily cause flowers to become diseased, suffer sunburn and die. On clear summer days, the light intensity at noon exceeds the suitable light intensity for most flowers by 1-2 times. If certain measures are not taken, most flowers will lose water and suffer sunburn. Therefore, summer flower production should generally include appropriate shading.

Besides reducing the impact of direct sunlight, shading also has the effect of significantly lowering the temperature. According to tests, shading generally lowers the air temperature inside a greenhouse by 4-5°C. Plastic shade nets can generally be used for shading; external shading works better than internal shading, and silver shade nets work better than black shade nets.

Shade nets come in certain specifications. Besides size, there is also the shading rate. The specific shading rate to use should be determined according to the light requirements of the flowers.
