How do you keep rosemary under control?

Answered by Randy McIntyre

To keep rosemary under control, it is recommended to trim back the entire plant by about one-third its height in late spring or early summer. This process helps to control the size and shape of the rosemary and promotes healthy growth. When performing the trimming, it is important to make the cuts in the succulent green stem portions of the plant.

Trimming the rosemary plant is relatively straightforward. Begin by assessing the overall size and shape of the plant. Identify any long, straggly branches or areas where the plant has become overgrown. These are the areas that will benefit from pruning.

Using a pair of sharp pruning shears or scissors, carefully cut back the branches or stems that need to be removed. Aim to make clean cuts just above a set of leaves or leaf node. This encourages new growth to emerge from that point. Avoid cutting too close to the main stem, as this can damage the plant.

As you trim, it is important to step back occasionally and assess the overall shape of the rosemary. Aim to maintain a balanced and symmetrical appearance. If one side of the plant has become larger than the other, trim back the larger side to create a more even shape.

In addition to controlling the size and shape of the rosemary, trimming also helps to rejuvenate the plant and promote healthy growth. It stimulates the development of new branches and foliage, which can result in a denser and bushier plant.

Trimming rosemary can also help prevent the plant from becoming woody and leggy over time. By regularly pruning, you encourage the growth of new, tender stems that are more desirable for culinary use.

It is worth noting that rosemary is a hardy plant and can tolerate fairly aggressive pruning. However, it is important not to trim off more than one-third of the plant’s total height in a single trimming session. Removing too much foliage at once can put stress on the plant and hinder its ability to recover.

To summarize the steps for keeping rosemary under control:

1. Assess the size and shape of the plant.
2. Identify areas that need pruning, such as long or overgrown branches.
3. Use sharp pruning shears or scissors to make clean cuts just above a set of leaves or leaf node.
4. Step back occasionally to assess and maintain a balanced shape.
5. Avoid removing more than one-third of the plant’s height in a single trimming session.

By following these steps, you can effectively keep your rosemary plant under control, promote its health and vigor, and ensure a bountiful supply of aromatic foliage for culinary use.
