Post Emergent kills weeds not grass

Do you have weeds in your grass and you're looking for a good solution to kill weeds in Lexington, Irmo or Columbia South Carolina?  Although the subject of weed control is very broad, I will attempt to address the question of what product to use at this time of year (summer) and what outcome to expect.  Weed controlling post emergent spray should be a part of your annual lawn weed control treatment plan.

Post emergent spray, not to be confused with PRE emergent (which we put down in granular form in the fall and in February) is a topical spray that when sprayed on many lawn weeds will yellow out and kill the weed to the root.  Some types of weeds like clover require 2 applications of post emergent.  As the name of the product implies, it is formulated to kill the weeds AFTER they have germinated as opposed to before they have germinated (pre emergent). 

Here is a centipede lawn that has been treated with post emergent, spray on application, 10 days after the chemical was applied.  Note ththat the weeds are yellowing out while the grass remains unaffected.



Post emergent is only one component of a comprehensive annual weed control program.  It should not be considered to be the "silver bullet", but, in my opinion, is one of the more effective spot treatments with nearly immediate results.  The timing of the application is critical - many post emergents should be applied well after the grass has come out of dormancy or it will affect the new, tender grass growth.



To apply this product, you basically just hook the hose-ready fitting on the bottle to your garden hose and apply as directed on the bottle.  Spray it on evenly and let it dry.  Be careful when using where there might be dogs or cats present as it can make them sick.  Don't get it in your pool.  Just use common sense, use enough to do the job, and that's it!
