[Translate to English:] Die Johannisbeeren verrieseln?

Coulure of raspberries? This might be the reason …

Coulure is often the result of a non sufficient fertilization of the flowers. Many varieties have to be fertilized by bees. If bad weather conditions stop the bees from visiting the flowers, the fruits cannot develop and the flowers drop down. Another reason might be frost or extreme drought during the blooming period. Shadow constitutes a further risk – therefore, raspberries should always be thinned so that all flowers get enough light.
