What is Interseeding???

Green Aerification

Interseeding is the process in which golf course superintendents try to introduce new grass to an area that already has a another grass growing.  It is not an easy process.  The process requires being very aggressive with the current stand of grass by aerification and verticutting.  Aerification pulls cores of material and grass out of the area and verticutting reduces thatch and makes it easier for the seed to be introduced.  Sand (Topdressing) should also be done. With good weather the new seedling should pop within a few days.  Once it has popped it struggles with the existing turf to survive.  Some grasses grow straight up and others grow sideways.  Depending on what you are trying to do, this is a challenge and becomes a superintendents finger nail biting time.  It is hopeful that you fill in areas that may have been stressed.  But cross your fingers that it works.  Other elements such as weeds and disease can cause a whole new set of problems.  If you have seen interseeding done or are interested in doing this application.  Do your homework and make sure it is right for you.
