If it does get cold again, we will see fewer hazelnuts this year, says Hoogenstein. Is this bad? “It can always happen that you have a different summer or winter. One year is not a problem, but if it happens for several years, then it is a serious thing. If a plant produces very few seeds, there is the chance that there will be no more young growth. If the old die without the new one, yes, then the plant is gone.”
Due to the heat, the hazel is already in bloom: ‘If it continues like this, it will become a kind of climate refugee’
