when do i harvest catnip seeds
1) When you should harvest catnip. Catnip is best harvested just before or immediately after it flowers. The chemical in catnip that causes Kitty's euphoric response is called Nepetalactone, and it's at peak concentrations in the plant just as it flowers. Click here for advice on how to grow catnip. It's best to harvest the plant on a dry day after dew has dried on the leaves - usually late morning or early afternoon. 2) How to harvest catnip. Remove the top part of the plant (leaves, stems and flowers) by cutting or pinching. Spread the plants out in a dry, well-ventilated area that's out of direct sunlight. This helps to maximize preservation and concentration of Nepetalactone.
