If we look at the summer alone, the shrub basil grows splendidly even far away from its tropical home. In winter, however, the tide could turn quickly, because the frost has already brought many a plant to its knees. Is this also to be feared with shrub basil?

Shrub basil must be overwintered in a warm place

Shrub basil abhors frost

The plant, which comes from regions of Asia and Africa that are warm all year round, is not genetically adapted to our winters. Its sensitivity to frost has remained, which is why this herb is considered completely non-hardy in this country. That is why the usual winter protection measures in the garden are in vain for him.

Cold is also unpopular

Even low plus degrees do not appeal to the edible shrub basil. As soon as the temperatures drop below 10 degrees Celsius, it has to do without fresh air and move indoors.

If the outside temperature fluctuates greatly in autumn, hibernation can be interrupted for hours or days. Though it takes a bit of effort, give this aromatic herb every hour of sunshine it can get.

Basil must overwinter in the pot

If you cultivate your shrub basil in a pot with foresight, it will be easy in autumn. In the garden bed, on the other hand, there is still dirty work to be done. The basil has to get out of the garden soil and into a pot. This should definitely be large and have drainage holes. Dig up the plant carefully so as not to damage its roots.

Find safe haven

Basil can still be kept in a warm room from spring to autumn. Its place in winter, on the other hand, should be a little cooler so that the perennial shrub basil gets a break.

  • winter frost-free and cool
  • Temperature values of 15 to 20 degrees Celsius are ideal
  • never make it warmer, avoid near the heating
  • the room temperature must not fall below 10 degrees Celsius either
  • Shrub basil needs light
  • if necessary set up a plant lamp (21.99€).
  • maintain a minimum of care
  • water regularly with small amounts of water
  • supply with herbal fertilizer once a month

tips

If the shrub basil is very sprawling, you can cut it before overwintering. In a cramped winter quarters, it finds space more easily. The cut branches are a useful cooking ingredient or can be used as cuttings for propagation.

harvest in winter

Harvesting does not have to end in winter. You may cut off shoots of the shrub at any time. But be a bit more cautious with the amount, because the basil will not grow back as quickly in the winter quarters as in summer.
