Historically, roses were handed down from one family member to the next by means of root cuttings. Here is a simple method for rooting.
Step 1: Cut a stem Cut a stem, 6 to 8 inches long, from the parent plant with a sharp knife or pruning shears. Cut at about a 45-degree angle. Do not allow the stem to dry out or become exposed to extreme heat or cold.
TIP: Wait until the peak heat of summer has passed before rooting.
Step 2: Remove the lower foliage Remove the foliage from the lower half of the cutting. Leave the foliage on the upper half.
Step 3: Dip in rooting hormone Briefly dip the cut end in a rooting hormone.
Step 4: Place the cutting in the ground Place the cutting in the ground in a location that is shielded from the hot afternoon sun. Rooting typically takes 4 to 8 weeks, depending on the weather and the rose variety.
TIP: Do not allow the cutting to dry out during the rooting period. Keep it well hydrated.
Step 5: Transplant the cutting Transplant the rooted cutting to its permanent location. Before long, you'll have a beautiful, blooming new rosebush.
