And if it is in a pot, it is advisable to water it 2-3 times a week during the summer and every 6-7 days the rest of the year, but if it is in the ground it will be enough to water it twice a week during the first year and then every 2-10 days the rest of the year.

Multiplication

  1. The first thing to do is fill a 10,5cm diameter pot with universal growing medium (you can get it here!).
  2. Afterwards, it is watered conscientiously and a maximum of two seeds are placed on the surface.
