Question
I read the article from Charlotte using sugar as an organic method to kill her Dallis grass ,Johnson grass as well as others.I have a new lawn 50% defiance turf fescue and 50% quack grass. I believe I received the quack grass from the straw covering the new seed. I put down about 15 pounds of sugar per 1000 square feet two days ago. Help Help What are
my options?

Answer
The super famous Charlotte espoused the use of sucrose for many ills in her Texas Lawn.  I say God bless anyone who can come up with a better way than Scotts to solve their problems.

This technique is not effective alas on Long Island soil.  Is it effective on your plot?  Do tell.

Up here, were I to be visited by the evil Quackgrass -- "Elytrigia repens" --  

Quackgrass is aggressive, it's perennial, and it ia found in Rye straw and fed to horses with daily feed to develop a shiny coat.  If you don't have horses, there's not much other use for it.

Michigan State University IPM has a Quackgrass page:

Look familiar?

This is a good excuse to use that SAT word UBIQUITOUS.  Ever see that word? This plant grows EVERYWHERE.  NOTHING is more UBIQUITOUS than Quackgrass.

The state government of Michigan honors this Weed on its official list of the Top 5 Most Common Weeds there.  Sort of like being on the FBI's Most Wanted List.

Quackgrass grows from thin, steel-strong, underground rhizomes.  Up close, these look like harmless roots.  Trouble is, they just WILL NOT DIE.

Young growing Quackgrass plants take 2or 3 months to develop these underground cables.  That means that you have a maximum THREE MONTH WINDOW to get at baby Quackgrass.  If you wait longer than that, it's a whole new ballgame.

Those Rhizomes put Quackgrass in a class all by itself.  If you have the bad sense to rototill a plot where just ONE Quackgrass plant is growing, you chop the rhizomes into pieces that grow roots all over the place.  They spread everywhere until they've taken over your plot the way the Germans took over Europe.

One mature Quackgrass plant produces apx 25 seeds after flowering in July.  Those seeds are viable for 4 years.

Depending on what you have, there may be different treatments.  Or there may not be.  Zipcode, please.
