Before you start propagating rosemary, it is crucial to select the right cuttings. The cuttings should be healthy and robust to produce a successful propagation. Here are some things to consider when selecting the right cuttings:

1. Choose the right time of year

Selecting the right time of year is key to the success of propagating rosemary. The best time to take cuttings is in the spring or early summer when the plant is actively growing. Avoid taking cuttings during the winter months when the plant is dormant.

2. Look for the right stem

Select a stem that is at least 2-3 inches long, with several sets of leaves. The stem should be healthy, green, and free of any blemishes or damage. Avoid stems that are woody or too thin, as they may not root properly.

3. Take cuttings from a healthy plant

It is crucial to take cuttings from a healthy plant to ensure successful propagation. Choose a plant that is disease-free and has not been exposed to any pesticides or chemicals. A healthy plant will have vibrant green leaves, strong stems, and a good root system.

4. Use sharp and sterile tools

Using sharp and sterile tools when taking cuttings is essential to prevent damage to the plant and the spread of disease. Use a sharp pair of pruning shears or scissors to make a clean cut. Sterilize your tools with rubbing alcohol before and after use.

5. Take multiple cuttings

Taking multiple cuttings will increase your chances of success. Take several cuttings to ensure that at least a few will root successfully. This will also give you the opportunity to choose the healthiest cuttings for propagation.

In conclusion, selecting the right cuttings is the first step to successfully propagating rosemary. Choose the right time of year, look for the right stem, take cuttings from a healthy plant, use sharp and sterile tools, and take multiple cuttings. Following these simple steps will increase your chances of successful propagation and lead to a healthy and thriving rosemary plant.

Step 2: Preparing the Cuttings

Once you have selected the right cuttings for propagating rosemary, the next step is to prepare them for rooting. Preparing the cuttings correctly will help to ensure that they are healthy and strong enough to take root and grow into mature plants.

1. Remove the Leaves

The first thing you need to do is remove the leaves from the bottom two-thirds of the cutting. This will help to prevent the leaves from rotting and encourage the stem to produce roots. If you leave the leaves on, they will compete with the stem for nutrients and water, which can slow down or even prevent root growth.

2. Trim the Stem

Once you have removed the leaves, use a sharp, clean pair of scissors or pruning shears to trim the stem. Cut the stem at a 45-degree angle, just below a node or leaf joint. This will help to promote root growth and prevent the stem from rotting.

3. Dip the Cutting in Rooting Hormone

Rooting hormone is a powder or liquid that contains growth hormones and other nutrients that can help to encourage root growth. To use rooting hormone, simply dip the cut end of the stem into the powder or liquid and shake off any excess. Be sure to follow the instructions on the package carefully, as too much rooting hormone can damage the cutting.

4. Plant the Cuttings in Soil

Once you have prepared the cuttings, it’s time to plant them in soil. Fill a small pot or container with well-draining soil and make a small hole in the center. Gently insert the cutting into the hole and pack the soil around it. Be sure to water the soil thoroughly, but avoid over-watering, as this can cause the cutting to rot.

5. Cover the Cuttings

Finally, cover the cuttings with a plastic bag or clear plastic wrap to create a greenhouse effect. This will help to keep the cuttings moist and warm, which is essential for root growth. You can also use a misting system or spray bottle to mist the cuttings regularly to keep them moist.

In conclusion, preparing the cuttings is a crucial step in successfully propagating rosemary. By removing the leaves, trimming the stem, using rooting hormone, planting in soil, and covering with plastic, you can help to ensure that your cuttings take root and grow into healthy, mature plants.

Step 3: Rooting the Cuttings

Once you have selected the right cuttings and prepared them properly, it’s time to root them. This is a crucial step in the propagation process, as it determines whether your cuttings will survive and grow into healthy plants or not.

Method 1: Water Propagation

One of the easiest and most popular ways to root rosemary cuttings is by using water. Here’s how:

  1. Fill a glass jar or vase with clean water and place the cuttings in it. Make sure that at least one node is submerged in water.
  2. Change the water every 2-3 days to keep it fresh and oxygenated.
  3. After 2-4 weeks, you should start seeing roots growing from the nodes. Once the roots are around 2-3 inches long, your cuttings are ready to be transplanted into soil.

Water propagation is a great way to monitor the growth of your cuttings and ensure that they are getting enough water and nutrients. However, it’s important to note that some plants may not respond well to this method and may develop weak roots.

Method 2: Soil Propagation

Another popular method of rooting rosemary cuttings is by using soil. Here’s how:

  1. Fill a small pot with well-draining soil, such as a mix of perlite and peat moss.
  2. Make a hole in the soil with a pencil or chopstick and insert the cutting. Make sure that the node is buried in the soil.
  3. Water the soil lightly to settle it around the cutting.
  4. Cover the pot with a plastic bag or wrap to create a humid environment for the cutting.
  5. Place the pot in a warm and bright location, but avoid direct sunlight.
  6. After 2-4 weeks, you should start seeing roots growing from the nodes. Once the roots are around 2-3 inches long, your cuttings are ready to be transplanted into a larger pot or garden.

Soil propagation is a more reliable method than water propagation, as it provides a stable environment for the cuttings to grow in. However, it requires more attention and care, as you need to make sure that the soil is moist but not too wet, and that the cutting is not exposed to direct sunlight or harsh winds.

Method 3: Hormone Propagation

If you want to increase your chances of success even further, you can use a rooting hormone to stimulate the growth of roots. Rooting hormones contain auxins, which are plant hormones that promote cell division and elongation, and can help the cuttings form stronger and faster roots.

Here’s how to use a rooting hormone:

  1. Dip the bottom end of the cutting in a rooting hormone powder or gel, following the manufacturer’s instructions.
  2. Tap off any excess powder or gel.
  3. Plant the cutting in soil or water as described above.
  4. Follow the same care instructions as for soil or water propagation.

Using a rooting hormone can increase the success rate of your cuttings by up to 20-30%, according to some studies. However, it’s important to use it sparingly and follow the instructions carefully, as too much hormone can harm the cutting and inhibit its growth.


Rooting rosemary cuttings is a simple and rewarding process that can yield a bountiful harvest of fresh herbs for cooking and aromatherapy. By selecting the right cuttings, preparing them properly, and using the right rooting method, you can ensure that your cuttings grow into healthy and vibrant plants that will provide you with years of enjoyment. Whether you choose to use water, soil, or a rooting hormone, remember to be patient and consistent in your care, and you will be rewarded with a thriving rosemary garden.
