- Choose new growth from the sides of the plant that are free of buds or flowers.
- The herb shoots should be cut so that they are between 2 and 4 inches long. Use sharp scissors or a blade to cut the stems.
- Bare the bottom one-inch of the stem once cut by removing the leaves. This helps to prevent rotting and also encourages root growth at these points.
- Firmly pack the soil for your herbs in a 4-inch pot. Then, use a pencil to make small holes inside the dirt around the edge of the pot.
- Place the herb cuttings inside the holes you made. Be sure to keep the water moist but not soaked, so that the dirt does not dry out. If desired, you can place a clear bag over the pot to help trap moisture inside.
