The most beautiful balcony plants shiver at temperatures below 10 degrees Celsius. Don't let the first warm rays of sunshine in spring tempt you into planting your balcony early. This short guide has the answer as to when it is safe to plant petunias, geraniums and other summer beauties.
Planting begins on the balcony from May
Cold Sophie gives the starting signal - plant after the ice saints
The Central European spring brings with it a climate phenomenon that poses a threat to sensitive balcony plants. Late frosts strike overnight without warning and freeze the first buds and blossoms. This capricious weather found expression in the distant past in an old farmer's rule that is still valid today for choosing the right planting date:
- Only plant sensitive balcony plants after the ice saints
- Wait until May 15, when the cold Sophie says goodbye as the last ice saint
In regions with harsh winters, we recommend planting flowers that are sensitive to the cold only after the cold weather at the beginning of June. In some years, cold air flows in from the north-west, causing the thermometer to drop by up to 10 degrees within a few hours.
