Overview
- The German Weather Service warns of nights near −3°C with showers, sleet and stronger winds, with storm‑force gusts possible in high areas such as the Black Forest highlands.
- Botanists expect most hardy native balcony and garden plants to tolerate the short chill, though blossoms are more vulnerable to frost than leaves.
- Plants raised warm in greenhouses or sold early face real risk, including French lavender, marguerite bushes, already blooming roses and kohlrabi.
- Gardeners can cover sensitive pots with fleece, sheets, newspaper, cardboard or bubble wrap, or place them by a warm wall or indoors to cut wind and cold.
- Advisers recommend waiting to plant tender stock until after the Eisheiligen in mid‑May, a traditional window when the risk of late cold snaps eases.
