November – Lawn Questions

November 16, 2017

I know most of your lawns are winding down for the year, however here are answers to several of your search questions that are popping up now on my blog pages.

  1. Is it too late to put down grass seed?

It is late to expect germination and enough root growth prior to winter weather in most parts of the country.  Some professional turf grass managers put down grass seed during early winter with the understanding that they will get germination in early spring.  This is called Dormant Seeding.  Here is a link to a blog posting I did last year on this subject.

  1. I am seeing moths flying from my lawn. Do I need to do anything?

If you are in the Deep South you can still get lawn damage from sod webworms and cutworms, especially on St. Augustinegrass.  Moths lay eggs for these insects that can thin your lawn and cause it to turn brown.   (Moths do not damage your lawn, just the worms that hatch from their eggs.)  You can treat your lawn with Ortho Bug B Gon MAX granules and this will kill all lawn damaging insects plus fleas and ticks.  If you use the higher spreader setting on the bag, you will also kill Fire Ants.  Water your lawn after spreading.  Other areas of the country do not need to treat as lawn moths do not lay eggs in cold weather.  They are looking for a place to overwinter.

  1. Can I still kill lawn weeds like Ground Ivy (Creeping Charlie)?

Yes, as long as daily high temperatures are getting to 45 degrees or higher you can spray your Ground Ivy (and other weeds).  There are various Ortho Weed-B-Gon products depending on where you live.  Click here to see your options.

Note:  If you planted grass seed this fall, it is best to wait until the new seedlings have been mowed four times before you apply weed killers.

  1. Is it too late to feed my lawn?

If you have only fed your lawn once this fall, you still have time to feed one additional time in most areas of the country except the very far North.  For example, Ohio State University Extension recommends giving lawns in the Buckeye State a feeding in Mid-November.  Turf Builder WinterGuard Lawn Food is a great choice.


The grass square on the left has strong roots because it has been well fed in late Fall. The grass square on the right is starving with very thin roots.  (This test was done in Ohio)
