Here are the main reasons to prune basil plants:

  • Plentiful harvest. The top reason to prune basil plant is harvest.

How to Prune Basil?

Now that you understand why you should prune basil, it is important to know how to do it properly. The first thing to keep in mind is timing. You need to trim your basil plants at the right time. With basil, it is best to start early: do the pruning when the seedlings are about 6 to 8 inches tall and have about 3-4 sets of leaves. This initial trimming is easy: simply pinch the main stem back until you are left with a set of side shoots. It should remove about one third of the plant. This will essentially double your basil harvest.

After this initial trimming of a young plant, you should wait for a few weeks until you prune basil again. Pruning every two weeks or so during the summer is great for encouraging growth and making your basil plant produce as much as possible.

But what if you don't have seedlings? If you have a mature basil plant that is much bigger and richer, the first step is to separate it into individual plants, since mature basil is often sold as a handful of individual plants in a pot.

After this, simply prune each individual plant back by about one third. Make sure to always cut just above a set of side shoots. This is the best way to stimulate growth on your basil plant.

In general, it is very easy to prune basil. You can even use your fingers, or a clean pair of scissors. Before you start trimming, take a look at your plant: the goal is to cut central stems back to a lover set of leaves. You will notice two tiny leaf buds emerging from the leaf axil, so always trim about a quarter inch above those leaf buds.

When pruning, always make sure to remove top sections of stems along with the leaves. Do not just remove individual leaves - this will not stimulate new growth. Keep this in mind when pruning your basil plants.

You can use this technique to prune basil flowers, too. As noted above, it is important to remove flowers as soon as they appear, or the plant will take too much of its energy into developing flowers, at the expense of leaves. Simply pinch buds as soon as they appear to encourage the plant to invest the energy into leaves.

Keep in mind that you can use flower buds in the kitchen. They, too, have a wonderful taste of basil and you can use them in your salads or other meals.
