Thank goodness neither you nor anyone in your family fell ill!

By the way, is that an olive tree in the front yard? How do you get it through the winter? Do you cover it or enclose it?
That’s a huge one! I’ve been taking care of mine for almost 15 years, but compared to that specimen, it’s tiny!

Thanks for your sympathy. Yes, it is an olive tree (supposedly frost-resistant down to -15°C (5°F)). I bought it in March or April through Planet Plazza. It was a little wish of mine. Recently, they had one at a Toom store at an insane price; I wanted to grab it again, but first I’m seeing how I manage to get it through the winter. We’re located about 450 m (1,480 ft) above sea level, so temperatures can get a bit colder. I guess it will get critical at around -5°C (23°F) of sustained frost (about one week). Above all, I want to protect the tree from wind. Most likely I’ll use a “sack.” For now, I’m not planning to install heating cables in the soil.

Then you were not in Timmendorf/Niendorf/Scharbeutz

In Großenbrode at the natural/north beach. The south beach, on the other hand, was cleared by the police at least once during our stay.

In a neighboring village, someone has also permanently planted an olive tree outdoors. They always shelter it over the winter, having built a kind of temporary greenhouse from wood and plastic sheeting or plexiglass that is assembled around the tree in autumn and taken down again in spring.
The olive tree has survived for several years now, and it is also larger. However, here we do experience colder periods for longer times.

Well, let’s give climate change a few more years, then no protection will be needed anymore.

We met with friends in Timmendorf on Saturday. It was a madhouse. I won’t be going to Timmendorf anytime soon.
Eckernförde is completely different in that respect.

Here is another picture of the olive tree. Since it is enclosed in a rectangular frame, I have already considered "closing it up" when it gets too frosty. Fairly simple: attach four wooden beams at the corners and seal the sides and roof with bubble wrap. My initial idea of using polycarbonate twin-wall sheets has been set aside for now due to the higher cost.
