Pre-Emergence Time


The weather is beautiful in Raleigh, NC today.  It’s March 10th and for anyone who cares anything about their yard, this is an exciting time.  We’re breaking out the mowers for the first time and the smell of freshly cut grass and 2-cycle engines is intoxicating.  It means that summer is on it’s way and pretty soon, you will no longer have to look into your neighbor’s houses from your back deck.  I know this is very exciting, but let’s talk about one of the key things you should be thinking about now that we’re almost half way through March.

Pre-Emergence herbicides are the lawn care professional’s secret to getting a good jump on the weeds-to-be that quietly lurk as little seedlings on or just below the ground.  It’s important to remember that pre-emergence herbicides stop the germination of almost anything, but they don’t do much for weeds that are already established.  This is also why this type of herbicide does not affect your grass at this time of the year.  Your grass is of course already established, even if it’s Bermuda or Zoysia and still lying dormant.  A very important note: If you are going to attempt to sow seed in a warm-season grass this spring, DO NOT APPLY pre-emergence herbicides to your lawn this Spring.  If you try to sow seed within X amount of time (usually about 45 days or so) of the application of pre-emergence; guess what?  Those seeds will not be emerging either.

It’s also important to realize that Pre-Emergence is usually applied with a rotary spreader in granular form along with a fertilizer application.  Check with a local professional or consult T1 Earthcare’s Grass Program section of this site by clicking here.  Also, please consult the manufacturer’s label on your product in order to better understand what you are actually applying.  When in doubt, it’s always a good idea to contact a professional.  Thanks for reading!
