The Ice Saints started on Thursday and will end on Sunday with Cold Sophie. According to biologist Eric Wyss from Globe Switzerland, the skin of plants, like humans, can be damaged by the sun, especially by high-energy UV rays.
This would heat up and damage the thin leaves of the plants. They turn brown and get a parchment-like structure. Herbs and vegetable seedlings with fine and thin leaves such as basil are particularly susceptible to sunburn.
Not only humans, but also plants could get used to the sun. Their cells could make their own sunscreen. They produced proteins that absorb the rays.
Seedlings from the shoot bed or window sill should be planted outdoors on a cloudy day. The conditions for this are ideal this Friday, SRF Meteo continues.
