Yes, burning bush spreading happens through both seeds and root suckers in your yard. This shrub produces thousands of seeds each year and sends up new shoots from its roots. Both methods help the plant take over large areas fast if you do not control it on time.
I found out just how fast this spreads when I looked under my mature burning bush last spring. There were over 200 seedlings growing in the mulch below the branches. UMD Extension says this pattern happens with most mature plants. Any shrub that makes berries will drop seeds that grow into new plants.
Does burning bush spread on its own without your help? Yes it does, and birds play a big role in this process every fall. They love the bright red berries that appear in autumn and eat them by the dozens each day. The seeds pass through their gut and get dropped far from the parent plant in wild areas.
Burning bush seed dispersal by birds creates a real problem for wild spaces near your yard. The seeds have a high rate of success when they land in good soil with moisture. They sprout in spring and grow fast into new shrubs that make their own seeds within a few years time.
The root suckering adds another layer to this problem that many people miss at first. New shoots pop up from roots several feet away from the main plant without warning. These suckers grow into full sized shrubs if you let them go without pulling them out soon. Each sucker can then make its own root suckers too over time.
Research shows just how bad burning bush invasive spread can get in natural areas over the years. A 1989 study in Illinois found an average of 7,809 stems per hectare in prairie areas where the plant had escaped yards. This dense growth crowds out native plants that wildlife needs for food and shelter to survive.
You can slow the spread around your own plants with some simple actions each growing season. Pull out seedlings as soon as you spot them in spring before the roots get deep into the soil. Cut off berry clusters in late summer before birds can eat them and spread seeds around your area.
Root suckers need your attention too or they will get away from you fast each year. Walk around your burning bush every month during warm weather and pull any new shoots you see growing. Grab them close to the ground and yank hard to get the whole root connection out at once.
If you want the fall color without the spread, look for sterile cultivars that do not make seeds at all. These newer varieties give you the same bright red leaves in autumn but will not fill your yard with baby plants. Check with your local nursery to see what sterile options they carry in stock for your zone.
