Summer temperatures have made many hobby gardeners want to plant. Now even frost is possible.

With some plants, you should now react quickly. If the thermometer falls below five degrees, there may be a risk of cold shock. If you already have boxes of geraniums, etc. hanging on your balcony, you should bring them into your house in the coming nights. Cool rooms are better suited for this than warm ones. There are also other ways to protect plants from frost. Cucumbers already suffer at temperatures below 10 degrees. Tomatoes are a little more robust, but should also be brought indoors overnight in the next few days. “Otherwise, the plants won't survive," says Klaus Moser, a specialist salesperson at the Seebauer garden center in Ramersdorf. The closer it gets to freezing point, the more dangerous it becomes.
