Growing Notes

  • These plants can grow huge, so pinching when they are about 30cm is important so you can harvest more usable stems

Harvesting Notes

  • Pick when about ¾ of the tiny flowers are open. It can be a little tricky to see at first, but look closely over time and you should see the difference.
  • Pick in the cool of the morning or evening to prevent wilting.
