You can propagate burning bush using two main methods that both work well for home gardeners. Seed propagation needs cold treatment before planting will work. Stem cuttings root faster in summer and skip the waiting time that seeds require.
In my experience, burning bush propagation from cuttings gives you results much faster than seeds do. Cuttings root in just 4 to 8 weeks during the warm months. Seeds need months of cold treatment before they will even sprout for you at all.
Growing burning bush from cuttings starts with taking the right type of stem at the right time of year. Look for semi-hardwood stems in mid to late summer when new growth has started to firm up. These stems root better than soft spring growth or hard woody winter stems do.
Cut a stem about 6 inches long from a healthy branch using clean sharp pruners. Strip the leaves from the bottom half of the cutting. Dip the cut end in rooting hormone powder to speed up root formation in the next few weeks.
Stick your cutting into moist potting mix in a small pot with drainage holes at the bottom. Cover the pot with a plastic bag to hold in moisture while roots form inside the soil. Keep it in bright shade and check the soil moisture every few days to make sure it stays damp.
Burning bush from seed takes more patience but works fine if you plan ahead in time. Collect berries in fall after they turn red and remove the seeds from the pulp. Rinse the seeds clean and let them dry for a day or two before storing them.
Seeds need cold stratification before they will germinate at all for you. Put them in damp sand or peat moss in a sealed bag in your fridge. Keep them cold at about 40 degrees Fahrenheit (4 degrees Celsius) for at least three months to break dormancy.
Plant your stratified seeds in spring after the cold treatment period ends. Sow them about half an inch deep in seed starting mix. Keep the soil moist and expect sprouts in two to four weeks once warm weather arrives.
Check your state laws before you start any burning bush propagation project at home. Many states have banned this plant due to its invasive nature in wild areas. Making new plants may be illegal where you live even if you already have one in your yard.
