Overnight air temperatures below ten degrees and getting closer to -20 C can cause damage to plants. Plus, Kurzeme has strong winds.
The risk factor for plants is that autumn was excessively wet and warm, which in many places contributed to secondary growth for fruit plants and berries - new shoots formed that don't quite mature. They are at the highest risk, along with newly planted plants.
In large fields, there is virtually no room to improve the situation, just waiting for snow to mitigate the damage.
Mulch, on the other hand, can help in smaller areas, which would help keep plants warm. “If there are autumn leaves left, then it's the right time to use them,” Narvils said.
The impact of the hoarfrost on yields cannot be predicted at this time.
