Can Coriander Survive Over Winter?

True coriander is an annual plant that originates from the regions of the Mediterranean Sea. Thus, the spice plant can not survive freezing temperatures. In addition, the summer flowering heralds the end of the short life of the plant, investing all the energy in the growth of seeds.

Koriander überwintern

An exception is Vietnamese coriander. The tropical knotweed plant is not related to the true coriander and has the potential for perennial culture. Thus, wintering in the protected environment of the room or conservatory succeeds:

  • put the plant away from temperatures of 10 degrees Celsius.
  • overwinter on a sunny, warm windowsill at 18 to 22 degrees Celsius
  • keep the plant slightly moist and fertilize it with liquid fertilizer every 6-8 weeks.
  • alternatively store in a cool, dark cellar at 5 to 10 degrees Celsius
  • water little and do not fertilize

If you want to continue harvesting the aromatic leaves during the cold season, a warm location comes into consideration. However, a cool winter break is more advantageous, so that the herb plant can gather fresh strength.
