Many people wait to harvest their basil plants until they are large. Waiting to harvest will give you more at one time, but harvesting early and often increases growth and allows your plant to produce much more overall.
When Should Basil Be Harvested?
Basil can be harvested at just about any time. Instead of harvesting a whole basil plant at one time, it’s best to harvest on as needed basis. The first several harvests start off small, so we typically use them as garnish. Over time you will be able to harvest enough to make things like pesto.
How To Harvest Basil To Promote Growth
When it comes to basil, harvesting and pruning are going to be pretty much the same thing. First, allow your plant to produce at least 2 sets of leaves. Next, clip the plants stem just above the 2nd set. I typically allow my basil to grow a little so I can at least have a small harvest. Below are some pictures of a basil I’ve started in an easy to build mason jar aquaponic herb garden.
Cutting the stem this way will cause the sets of leaves to shoot out like they are the new tops of the plants. Allow them to grow and cut those as well, repeating the process over and over again.
With each leaf you clip or shoot that you top off, it will produce more new growth from your basil. Be cautious not to over harvest. To prevent the plant from dying after harvesting or pruning, leave about a 3rd of the plant growth, so the plant can create energy for new growth.
