Unfavorable climatic conditions can cause the grapevine to lose flowers
When does it come to a grapevine to trickle the blossom?
From mid-May to late June, the flowering period of a grapevine stretches. 45-90 days have passed since the sprouting, so that the flower spikes thrive on numerous shoots.

Various grape varieties have proven to be particularly vulnerable, such as Merlit, Malbec or the popular Gewürztraminer. By choosing resistant finishing documents, there is the possibility of a preventive influence.
