How to spot it
Blossom wilt infects stone fruit through the open flower and travels from there into the shoot. Affected blossoms and shoot tips wilt abruptly and dry up brown, as if frost had caught them. That is why it is often mistaken for frost damage. Sour cherries such as ‘Schattenmorelle’ are particularly susceptible when the weather is cold and wet at flowering time.
Prevention
Cut infested shoots back quickly to about 15 cm into healthy wood and dispose of them with the residual waste. Choose less susceptible varieties and thin the crown by pruning, so that it stays airy and dries off quickly. If it rains continuously during flowering, a preventive treatment with clay or horsetail preparations helps.
