Step 1
Select plants. Certain herbs, such as tarragon, can only be propagated through cutting or division to give them their flavor. Annuals need to be started from seed each year. When taking cuttings, only do so from healthy plants, in late spring or early summer.
-
Step 2
Expose the roots. Carefully expose sections of root from your chosen plant. Roots to be cut should be about the thickness of a pencil.
-
Step 3
Cut the roots. The portion closest to the body of the plant is cut diagonally, and the root end is cut straight. Cut a section about 2 inches long.
-
Step 4
Place in soil. Use a rich potting soil or compost, making sure it is moist. Cover with half an inch of vermiculite to keep moisture in. Covering the pot with plastic will maintain a high level of humidity for your cuttings.
-
Step 5
Keep in a sheltered spot. The pots need to be out of direct sunlight. Wait four to six weeks, making sure your soil stays moist during this time.
-
Step 6
Transplant to separate pots. This will give the new plants room to grow without their roots becoming entangled with the other plants. They can be allowed to grow over the winter in a protected location. Do not allow them to freeze. The plants will be ready for their permanent location in the spring, after all danger of frost has past.
