The bottlebrush plant has an unusual bloom that really does look like a bottle brush. The spiky flower colors are found in red, mauve, pink, cream and green. Once a bottlebrush is established in the garden, take cuttings from it to produce new plants. These also make inexpensive gifts for friends, family or office co-workers, when planted in an attractive pot after roots have formed.
Rub your garden clippers with alcohol, to disinfect them. Cut right above the joint of a limb of a bottlebrush plant with the clippers. The cutting should be at least 10 inches long. Cut at an angle, as you would cut flowers. Place the cut end in a container of water, immediately.
Create a mixture of equal parts peat moss and sand. These ingredients can be purchased from garden centers or nurseries. Fill a container with the mixture.
Make an indentation in the peat moss mixture, about 5 inches deep, with a pencil or thin dowel.
Dip the cut end of the bottle brush limb into rooting gel (found at nurseries or garden centers). The gel gives the limb the proper nutrients to start rooting.
Place the bottle brush cutting into the hole made in the peat moss mixture. Use your fingers to work the mixture around the cutting, until it is secure.
Water the peat moss mixture just to retain moistness. Check often, by digging into the material with your finger. Do not over water, as this could cause the formation of mold. The cutting should be ready for transplanting in approximately six weeks.
