how do you propagate forsythia?
Commercially, forsythia is usually propagated by taking hardwood cuttings when the plant is dormant in mid-winter. You can also take hardwood cuttings after the new growth has hardened off or become woody in mid to late summer. Another simple method to propagate forsythia is by layering. In this process you simply bend a branch down to the ground and bury a section of the branch. It may help to wound the buried section and apply rooting hormone to the wound. In several months, roots should develop on the buried section of stem. At that time you can sever the layered section from the mother plant and transplant it to a new location.
