Fruit growers currently relaxed despite frosty nights

Protection options are limited

Fruit growers still have a few options to protect their trees. However, it also depends on the temperatures. "At seven degrees below zero, there's nothing you can do," said Kaps.

In addition, not every farmer can take protective measures. The most effective method is frost protection irrigation, where the trees are watered on cold nights. This creates a protective layer of ice around the flowers. However, this requires large quantities of water, said Kaps. "Not everyone can irrigate."

Lighting frost protection fires on the plantations also only has a limited effect. The heat does not radiate far enough to protect an entire tree. In the worst-case scenario, one side could burn and the other still freeze to death. Wrapping the apple trees in fleece to protect them from frost like a small tree on the balcony at home is impossible on the large areas of fruit farms.
