In August it can get really hot again. Nature also suffers from the strong sunlight. The intense UV light can cause serious damage such as local death of plant tissue and crop failure.

detect heat damage
kind | damage picture |
---|---|
ornamental plants | Drops of water focus the sun's rays and act like small magnifying glasses. This becomes a particular problem for plant leaves with fine hairs, which are easily sunburned. This leaf damage is irreversible. |
vegetables | Heads of lettuce exposed to the sun show burns from direct sunlight that reach into the interior. Celery gets leaf necrosis, cucumber white, very limited spots. The cauliflower will become inedible and brown if the flower is not protected from UVV radiation. |
fruit | Bright, later brown spots appear on apples as a result of intense sunlight. This damage often continues in the pulp. In connection with a lack of water, the leaves turn yellow and shed prematurely. As a result, the fruits remaining on the tree no longer develop. |
Berry | These wither, become soft and wrinkled. Dark berries warm up with heat as much as if they were being boiled. They then fall off and are inedible. |
These measures will help
- Place potted plants in the shade on hot days or provide sufficient shade, for example with an awning.
- Bird protection nets and fleeces not only protect berry bushes and fruit trees from having to share the harvest with your feathered friends. The nets also provide some shade.
- Vegetable plants should also be protected from the heat and direct sunlight by fleece or netting.
- Water in the early morning or evening hours. Water regularly, on very warm days this may even be necessary twice a day. In this way you protect the plants from additional stress caused by a lack of water.
tips
Carefully acclimate plants that have overwintered indoors to sunlight in the spring. Place potted plants in a shady spot and initially only expose them to morning or evening sun.
