Weeds & Fall Insects in the lawn

So why should I fertilize the lawn now?  A little fertilizer now can get that tired, worn-out lawn looking great after all the heat this summer had to offer.  Now is a time when we can really enjoy the yard and when the grass can look as good as it did this spring without growing out of control.  Fertilize either with a good slow release nitrogen like 23-3-16 or South-West Greenmaker or if you have a few weeds, go with a weed-n-feed.  You’ll be surprised what a difference it can make.  Just don’t forget to put your winterizer on later.  Just because you are fertilizing now, doesn’t mean it’s ok to skip an important step later.  And if you have had stress, insect, or disease damage in your lawn, don’t hesitate to add an extra dose of humate.  It will help your lawn recuperate in about half the time.
Few weeds dare show their ugly heads in my lawn, but a handful of bold invaders sneak in every now and then.  While I truly adore using my long handled weeder to chop the villains to bits, an herbicide, applied correctly in the Fall, will invoke miracles.  2,4-D, or Triamine, or Trimec all will kill weeds effectively this time of year (seeping down deep into the roots to kill the entire plant).   A good weed-n-feed will contain one of these herbicides.  I prefer using the liquid Trimec when necessary or, for the exceptionally tough weeds like violets and morning glory, I use Carfentrazone.   Not only is it a “safer” herbicide, but it works on the most difficult to control weeds around morning glory, thistle, wild violets, clover, spurge, mallow, etc.  And unlike other herbicides, it reacts fast.  Usually one application will kill just about any weed within just a few days.  There are few new products out that have generated as much excitement as this one.  If you have hard-to-control weeds in your lawn, I know this product will work for you.
Insects have plagued lawns all summer, but just within the next 10-14 days  sod webworms will start showing up in lawns in almost every community in the valley.  Almost overnight small yellow spots will appear in the lawn, growing in size each day, and turning brown.  The turf will lift up very easily revealing 3/4 inch long worms with a small, brown head chewing up the grass stems right where they emerge from the soil.  For excellent organic controls of these nuisance pests use Spinosad or Mach II.  Both of these controls stop the webworms from eating within 24 hours or less, but it takes as long as 2 weeks for them to die.  For a quicker demise, Dylox, Tempo, Permethrin, and Deltamethrin have specific labeling for the control of webworms in lawns.  They all come in a liquid or a granulated form and will kill them in 12-24 hours.  Be certain to treat all the effected areas and surrounding lawn to prevent their return later this fall.
