Do succulents fear sun exposure in summer?
Regarding the question of whether sunscreen is needed on cloudy days in summer: cloudy days do not mean there is no UV radiation, it's just that the intensity level of UV radiation is low, making it less likely to cause sunburn. Therefore, on cloudy days during the high-temperature period of summer, if the sunshade net is opened, it is essential to maintain good ventilation and keep the potting soil dry to avoid the simultaneous occurrence of high temperature and high humidity, which is generally safe.
About the need for sunscreen for succulents on cloudy days in summer
Cloudy days do not mean there is no UV radiation, it's just that the intensity level of UV radiation is low, making it less likely to cause sunburn.
So, on cloudy days during the high-temperature period of summer, if the sunshade net is opened, it is essential to maintain good ventilation and keep the potting soil dry to avoid the simultaneous occurrence of high temperature and high humidity, which is generally safe.
Main methods of sun protection for succulents in summer
Choosing a suitable breeding environmentIf the number of succulents is not large, it is better to choose a cool and well-ventilated environment with diffused light than to install a sunshade net, as long as there is no long-term direct sunlight and good ventilation, such as: north-facing balconies, window sills, shaded areas of the courtyard, etc.
During the summer, succulents are in a state of dormancy or semi-dormancy, so moderate watering and keeping the potting soil dry are beneficial to prevent discoloration, etiolation, and to prevent black rot and waterlogging.
Installing a suitable sunshade netFor a large number of succulents, outdoor balconies, or exposed succulents, installing a suitable sunshade net is necessary, as it can effectively protect the succulents and also avoid the trouble of moving them in and out.
But it should be noted that sunshade nets are of different densities, and different densities result in different shading rates. Generally, a density of 3 needles, or a sunshade net with a shading rate of about 55%, is chosen for shading plants in summer.
In the hot stove cities in the south, a density of 4 needles or a shading rate of 70% can also be chosen, but the denser the net, the poorer the ventilation effect, so when installing, it should be installed as flat as possible and leave some ventilation openings.
How to deal with sunburn on succulents in summer
When succulents are sunburned in summer, do not take the approach of spraying water to remedy it. First, move it to a cool and well-ventilated place to recover, and then deal with the severity of the sunburn: severely sunburned leaves can be removed or the plant can be topped.
Mild sunburn, except for some sun spots, generally does not affect the survival, and the sunburned leaves can be consumed during the later growth metabolism.
