What should we keep in mind while planting oregano?

There are several things that we should consider while cultivating oregano. Those are mentioned below:


The soil must be well-drained and light. Oreganos can even grow in less fertile soil, so you do not have to fertilize the soil. You just plant them and let them thrive by themselves.


Oregano grows well in full sun. All its flavors develop if they are left in the sun for a full day. You can grow them indoors too, but make sure they get the necessary sunlight and warmth.


You should only water oreganos when the soil seems to be dry. Overwatering oreganos can be very harmful to the plant. One should thoroughly water it once a day.


One should leave adequate gaps between their oregano plants. They grow two feet tall and 18 inches wide. So, you must leave at least a 10 inches gap between each plant. If you are using a pot to grow oregano, make sure that it is 12 inches wide.


Oreganos can be planted with any other plant. No matter whatever you plant beside oregano, they will grow harmoniously together.


If you want to make your oregano plant grow thicker, cut the stems as they grow four inches tall. This enhances the growth and density of oregano plants.

So, if you consider all these aspects, you can successfully harvest oreganos outdoors or indoors.
