How to get rid of bent grass ?
Question:My front lawn looks great except for these patches of lighter colored grass my landscaper says is "bent grass". He claims that it comes from using cheap seed (which is entirely possible, as our builder was fairly notorious for taking shortcuts with landscaping) and there really isn't much you can do about it short of tearing it out and reseeding in the fall.
Its widespread enough that I cant see tearing it out...it would mean tearing up almost the entire lawn if we wanted to get it all.
Any other options ? I'm not against chemical herbicides but I'd rather avoid using them if possible.
For reference...we live in New England and the lawn is a mix of Kentucky Bluegrass and fescue.
Answers:
There is no selective control for Creeping Bentgrass in a mixed KBG/fescue lawn. Best to RoundUp the affected areas and reseed or sod. Creeping Bentgrass seed can blow into your lawn from nearby golf courses. Be aware that some golf courses are now using a RoundUp Ready Creeping Bentgrass (genetically altered to resist RoundUp), should RoundUp not work, then try Vantage or Envoy.
