Fill a 6-inch pot with well-drained potting soil. Three or four cuttings can be put into each pot, so fill as many pots as needed.
Examine the stem of the Grevillea bronze rambler in the summer and find the semi-hardwood stems or where the stem color changes from green to brown.
Cut a 4- to 5-inch semi-hardwood stem with pruning shears right below the leaf node.
Remove the leaves from the bottom half of the stem. Leave at least two leaves at the top of the cutting.
Wound the stem by scraping away a small sliver of bark to expose the living tissue.
Dip the cut end in a glass of water. Shake the cutting to remove the excess water.
Dip the wet end into rooting hormone. Shake the cutting to remove the excess rooting hormone.
Poke three or four holes into the potting soil with a pencil. Space each hole an equal distance apart.
Insert the end of the cutting with the rooting hormone into the hole and firm the soil around the stem with your fingers to hold it in place.
Water the soil until it is moist. The water will run out the drainage hole at the bottom of the pot.
Place a clear plastic bag over the top of each pot. Place two wires or sticks inside the pot to keep the plastic from touching the leaves of the plant.
Check the soil daily and add water to keep the soil moist, but not soggy, or the cuttings will rot.
Check the cuttings for new growth. This indicates that the cuttings have rooted. Remove the plastic bag.
Transplant the cuttings into individual 6-inch pots filled with well-drained potting soil or into your garden area when all danger of frost is past.
