Question
I had nitrogen applied to the lawn 4 weeks ago.  There are areas that have not greened as much as other areas.  Will another application help this situation?  Do I run any risk of injuring the lawn if I reapply nitrogen now?
Thanks

i'm in southern NJ.  it depends on where you live, how much watering has been done since the application, how high the Nitrogen percentage was, and how much was applied the 1st time...
normally a 2nd high N application can be done 30-60 days after the 1st was done.  if temps are too high(over 90) wait until the day temps get down into the 80's again.  make sure you water it in after the application so the grass blades don't get burned. make sure you use a good spreader device to deliver the fert application evenly over the entire lawn.
get to a local garden center/nursery and quiz them on a solution to your problem for your particular area.
good luck
