In Germany, grapevines were grown under glass for a long time before being replaced by cheap imported grapes. The much dreaded powdery mildew, a disease which started in an English glasshouse around 1850, also contributed to the end of this grape culture. But with new, fungus-resistant grapevine varieties comes a revival of this tradition, and every enthusiast can again produce delicious table grapes under glass, on carports, porches, or in plastic greenhouse tents.
Particularly suitable varieties for greenhouse cultivation are "Blue Muscat" and "Birstaler Muscat," as they grow without moisture, without contact with rain or dew and without sulfur spraying. Their cultivation can be shared with other, low-light loving plants.
