Koriander Balkon

Sowing seeds in the balcony box – it’s so easy.
Coriander does not like to be transplanted. To spare the spice plant the stress, we recommend sowing directly into the planter. The best time to start is from the end of March to mid-April. How to do it right:

  • the perfect balcony box is at least 45 cm wide and 25 cm deep
  • spread a thin layer of grit over the water drain in the bottom as drainage
  • fill with herbal soil or a mixture of potting soil and sand and moisten it
  • scatter the coriander seeds and as light germinators sift over a maximum of 0.5 cm

In the semi-shaded window place at an ideal 20-25 degrees Celsius, germination begins within a week. If you place the planter on the still cool balcony, the seeds take a little longer. Keep the sowing and the seedlings constantly moist. If the planting box is crowded, select the weaker specimens to a planting distance of 15-20 centimeters.
