Propagating Rosemary: From Cuttings to Culinary Herbs

Master the art of cloning your favorite woody rosemary plant with this simple step-by-step guide.

Rosemary is a fantastic plant for propagation because it roots reliably from stem cuttings. Whether you want to expand your indoor herb garden or gift a living starter to a friend, this method ensures a genetically identical copy of your parent plant.

What You Will Need

  • Healthy, non-flowering rosemary stems (4-6 inches long)
  • Clean, sharp pruning shears
  • Small pot with drainage holes
  • Well-draining potting mix (perlite/sand mix)
  • Optional: Rooting hormone powder
Make a clean cut just below a node to encourage root development.

Step-by-Step Propagation

  • Select a healthy stem tip about 4-6 inches long; avoid stems that have already flowered.
  • Use sanitized shears to make a clean, 45-degree cut just below a leaf node.
  • Strip the leaves off the bottom 2 inches of the cutting, leaving only the top cluster of foliage.
  • Dip the wounded end into rooting hormone if you want to speed up the process.
  • Insert the cutting into a moist potting mix, burying the leafless part of the stem.
  • Place in a spot with bright, indirect light and keep the soil slightly damp.
Pro tip

Create a mini-greenhouse by loosely covering your pot with a clear plastic bag to retain humidity, but ensure you vent it daily to prevent mold.

Avoid overwatering your cuttings. Rosemary is drought-tolerant and prone to stem rot if left sitting in waterlogged, stagnant soil.
