How To Propagate Rosemary: Turn One Plant Into Dozens

Propagating rosemary is a great way to expand your herb garden and turn one healthy plant into multiple plants. Rosemary can be propagated from cuttings, and here’s how you can do it:

Materials you’ll need:

Healthy rosemary plant: Choose a mature rosemary plant with strong, disease-free growth.

Pruning shears or sharp scissors: For taking cuttings.

Rooting hormone (optional): Rooting hormone can encourage faster root development but is not essential.

Small pots or containers: To plant the cuttings.

Potting mix: A well-draining mix suitable for herb propagation.

Plastic bags or plastic wrap: To create a mini greenhouse for humidity.

Steps to propagate rosemary from cuttings:

Select the parent plant:

Choose a healthy rosemary plant with strong, disease-free growth. The best time to take cuttings is in the spring or early summer when the plant is actively growing.
Prepare your cuttings:

Use sharp pruning shears or scissors to cut 4-6 inch (10-15 cm) stem cuttings from the parent plant. Cut just below a leaf node (the point where a leaf attaches to the stem). Remove the leaves from the bottom 2-3 inches (5-8 cm) of each cutting.
Optional: Use rooting hormone:

You can dip the cut end of each cutting into rooting hormone powder. This can promote faster root development but is not necessary for success.
Prepare planting containers:

Fill small pots or containers with a well-draining potting mix. Water the soil lightly to ensure it’s evenly moist but not soggy.
Plant the cuttings:

Insert the prepared cuttings into the planting containers, burying them about 2-3 inches (5-8 cm) deep. You can plant multiple cuttings in the same container, but ensure they are not overcrowded.
Create a mini greenhouse:

Cover the containers with a plastic bag or plastic wrap to create a mini greenhouse effect. This helps maintain humidity around the cuttings.
Place in a bright location:

Put the containers in a bright, indirect light location. Avoid direct sunlight, as it can scorch the cuttings. A windowsill or under grow lights can work well.
Maintain humidity and moisture:

Check the cuttings regularly to ensure the soil remains evenly moist. Mist the inside of the plastic covering if it appears too dry. You can remove the cover occasionally to allow for fresh air circulation.
Monitor root development:

After several weeks, gently tug on the cuttings to check for resistance, which indicates root development. Once the cuttings have established roots (usually in 2-3 months), they can be transplanted into larger pots or the garden.
Transplant to the garden or larger pots:

Once your propagated rosemary cuttings have well-developed roots, you can transplant them into larger pots or directly into your garden. Choose a sunny location with well-drained soil for planting.
By following these steps, you can successfully propagate rosemary from cuttings and turn one healthy plant into multiple plants to enjoy in your herb garden.
