3. Why prune basil?
Almost all the plants in your garden need to be pruned, but the reasons why they need it vary from one to another. In the case of basil, I can name three very important reasons:
- Maintain the general health of the herb.
- Ensure a good amount of leaves during the season. And extend this harvest as long as possible.
- Make sure the taste of the leaves is at its peak.
In case you do not prune, you will have very tall and lanky plants with poor leaves. It will also begin to bloom, something that does not favor the taste of the leaves.
4. How and when to prune basil plant
As we said, pruning this aromatic herb is simple, but it is necessary to know some keys to do it correctly. Especially if what you are looking for is to have a good harvest of its leaves to be able to enjoy them in the kitchen.
We will analyze here three prunings that are essential to ensure that we have a healthy basil and at the same time we can harvest its leaves as long as possible. These pruning are:
- Cleaning pruning
- Pruning to make it bushy.
- Flower pruning.
Since they do not have the same purpose and must be carried out differently, we will analyze each of the previous prunings separately.
4.1 Cleaning pruning
If you check the information on the internet on how to prune basil, you will notice that everyone focuses on pruning to increase grass production, and in no case will they talk about cleaning pruning. They probably don’t consider it important, but this pruning will help you keep the plant healthy, so you can’t forget it.
There is nothing complicated in cleaning pruning. It is enough to periodically check the basil and cut all the diseased elements, attacked with pests or dried.
If you find diseased branches or leaves or strongly attacked by a pest, do not hesitate to cut. In these cases, try not to leave pruning waste near other plants in your garden, get rid of them. Otherwise, it will help to spread the disease or plague.
4.2 Pruning basil to make it bushy
We arrive at the most important pruning you should do if you want to increase the production of leaves during the season. If carried out correctly, it will not only increase the amount of the crop, but will extend the production time and will have bigger and tastier leaves.
As you have noticed, basil develops in groups of leaves, in general you can begin to perform this pruning when the plant exceeds 6 inches in height, or at least it has three or more groups of leaves. Before that, it is better to let it develop freely.
Once the appropriate size has been reached, pruning consists of cutting the stem just above a group of leaves, half an inch from the junction of the leaves with the stem. At the meeting point between the leaves and the stem, you should see other small leaves, from which two new stems will be generated.

If you cut those two new branches in successive pruning, two more will come from them, and so on. So you make your basil more bushy.
As I told you before, this pruning should begin when the plant measures approximately 6 inches and should extend throughout the harvest season. Do not be afraid to cut, this herb develops quickly, to the point that you can perform this pruning every 15 days. Try to prune the entire plant constantly. Don’t cut some sheets arbitrarily every time you need them in your kitchen. Remember that it has many uses, you can even dry or freeze them.
If you do the pruning according to the instructions it will also help you to prevent the plant from blooming, something quite unpleasant since at that time the leaves lose their original flavor, becoming more bitter and soft.
4.3 Pruning basil flowers
While it is true that it is better not to allow basil to develop its inflocences, it is true that it often happens. If that happens, and if you want to continue harvesting some leaves during the season, you should prune them.

You must cut the inflocences, with scissors or with your own hands, just below the pair of leaves that develop next to the spike.
You will see that in the following days the plant will reactivate producing more and better leaves. Although, as I warned you, the leaves may lose their flavor to some extent, in addition to being smaller. With this pruning it is possible to prevent the plant from completing its natural development cycle, thus extending its useful life.
