Cuttings:
Acacia baileyana 'Variety Purpurea' can also be propagated through stem cuttings. Take a healthy stem cutting of 4-6 inches long, remove the leaves from the lower half and dip the cut end in rooting hormone. Plant the cutting in a pot filled with moist soil and cover it with a plastic bag to maintain humidity. Roots will start to grow in about 4-6 weeks.
Air Layering:
Air layering is another method of propagation that is ideal for Acacia baileyana 'Variety Purpurea.' Select a healthy stem and make a small cut at the base of the stem where you want the roots to form. Pack wet sphagnum moss around the cut area and wrap it with plastic wrap to keep the moisture in. Roots will start to grow in about 6-8 weeks. Once the roots have grown sufficiently, the stem can be cut off and planted in a pot.
