Oregano is possibly one of the most recognised herbs in the cook's garden, oregano is easy to grow and adds plenty of taste to food. It's fantastic when cut fresh from the plant and can easily be dried for long-term storage. Oregano is an aggressive plant that likes to spread and a bush of oregano can grow quite large if you allow it. Most oregano varieties need full sun. If your soil is moist with lots of organic matter, oregano will not perform as well as it does in lighter, drier soil that is typically well-drained. Allow the soil to dry out fully between waterings. Do not overwater oregano. Water thoroughly only after the soil is dry to the touch.
