Sunburn and drought damage

Fruit that hangs in full sun can grow in periods with tropical temperatures (> 30ºC). Brown burn marks appear on the fruits in nearly ripe apples . In case of severe burning, the underlying pulp will rot.
Small fruit ( raspberries , currants ) usually hang below the leaf. However, sun-exposed raspberries and berries can burn. Cut away the affected fruits.
Gooseberries usually don’t hang in the shade, gooseberry bushes don’t have enough leaves for that. Planting in partial shade (preferably only sun in the morning) prevents fire damage to small fruit.
Summer pruning of apples and grapes is best avoided during hot summers; both are prone to drought damage during times of drought and heat waves.
Pears have a thicker skin and are therefore less sensitive to sunburn.
Grapes should also be protected from the sun during very hot weather; sunburn almost certainly occurs when a truss from the shade suddenly hangs in the sun. Cut away the affected grapes.
Make sure that the fruit trees and berry bushes have access to sufficient water; to prevent the soil from drying out, the grass around the trees and shrubs can remain a little longer.
Water regularly, the occasional large splash will give the fruit a growth spurt, making the skin thinner and more susceptible to sunburn.
The trunk of beech is extra sensitive to sunburn, by wrapping the trunk with jute sunburn is prevented and thus vertical cracks in the bark. Sunburn of the trunk is caused by a combination of a lot of sun, a high temperature and drought stress of the tree, which causes the temperature of the bark to rise too much (> 40°C) and tissue damage occurs.
Hydrangeas do not tolerate bright sun well. During a heat wave, the leaves and umbels dry up. Shielding and regular watering (at the roots) can prevent this.
Grass also suffers from drought: do not mow it too short and leave the mowed grace. This clippings protect the grass rooting on the surface s against dehydration.
