Basil is not native to Central Europe, but immigrated to us from tropical regions in the 12th century. Thus, the herbal plant is not endowed with a hardy constitution. In order for the popular royal herb to thrive in the bed and on the balcony, the focus is on the following optimal temperatures.
- the seeds are only in the mood to germinate at 20 to 25 degrees Celsius
- planting outdoors is only possible after the ice saints, when there is no longer a threat of ground frost
- In the bed and on the balcony, 10 to 12 degrees Celsius is the absolute minimum temperature
- ideal growth conditions prevail at a warm 20 to 25 degrees Celsius and higher
If perennial varieties of basil move to the windowsill or the heated greenhouse in good time, there are good prospects of a successful overwintering. Top premise here are temperatures of 18 to 22 degrees in a sunny location.
