What A Creep

leave a comment »

 I had an email earlier this week regarding Creeping Charlie removal … I’m no turf expert, but am happy to pass along a few basic management tips!

Creeping Charlie, Glechoma hederacea, is a ground ivy found in the mint family (so has square stems).  The perennial weed is very prolific by seed and also spreads by stolons*.  Creeping Charlie is a European native that was introduced to the United States by early settlers who thought it was a good groundcover for shade.

In some cases, hand removal is an easy solution.  When the ground ivy is taking over your turf, more drastic measures might be necessary.  When spraying, there are better times than others to attack.  Ideal time is fall, when the plants are preparing for winter and sending food to their roots (so chemical moves all through plant) and second best is in the spring when in bloom.  Weeds in general are more susceptible to chemical control when flowering.  Best application temperatures are in the 60 to 80 degrees range with no rain in the immediate forecast.  It is also best not to mow two days before and after application.  If the turf is severely infested, it might require more than one application.

See you in the gardens.

 

* Stolons, also called ‘runners,’ are horizontal stems that root at the nodes.  Rhizomes are also horizontal stems, but are usually found under the soil surface.
