The Root of the Matter: Propagating Rosemary with Ease

Rosemary, a beloved herb known for its aromatic fragrance and culinary uses, can be propagated with a near-perfect success rate when the right conditions are met. Here’s how you can achieve a 99% success rate in propagating rosemary, especially when growing it in a south-facing window using a humidity dome tray.

Choosing the Right Cuttings

The key to successful propagation starts with the right cuttings. Choose healthy, disease-free stems from an actively growing rosemary plant. The best time for taking cuttings is during the plant's active period, from spring to early summer.

Preparing the Cuttings

Once you have your cuttings, which should be about 4-6 inches long, strip the leaves off the bottom two-thirds of the stem. This will expose the nodes where the roots will develop. For an added boost, dip the cut end in rooting hormone before planting.

The Ideal Setup: South-Facing Window and Humidity Dome Tray

A south-facing window provides the optimal light conditions for rosemary cuttings to thrive. The consistent, bright light warms the soil and encourages root growth.

The humidity dome tray is crucial for maintaining the right moisture levels. These trays create a mini greenhouse effect, trapping humidity and warmth, which are essential for root development. Make sure the dome has adjustable vents to control the heat and humidity levels.

The Perfect Growing Medium

The growing medium is just as important as the cuttings themselves. A well-draining potting mix that will retain moisture without becoming soggy is ideal.

Caring for Your Cuttings

With the cuttings in place, covered by the humidity dome, and set in a south-facing window, you’re well on your way to success. Monitor the moisture levels regularly, ensuring the soil is moist but not waterlogged. Adjust the vents on the humidity dome as needed to maintain the ideal environment.

Patience is Key

Rosemary cuttings can take several weeks to root, so patience is essential. After about 4-8 weeks, gently tug on the cuttings to check for resistance, indicating root growth.


Once the plant has rooted and the roots are established, you can transplant your new rosemary plants into larger pots or your garden. Continue to provide them with plenty of sunlight and well-draining soil, and you’ll have a bountiful supply of rosemary for your kitchen and garden.
