Click below to listen to my Garden Bite radio show: Fall herbicide care and sowing seeds
Now into October is the time to apply a herbicide for those broadleaf weeds. Fall is the BEST time to attack them. Broadleaf weeds include dandelion, plantain lily, white clover and wild violets. After treatment, these guys will begin to die off and by Spring, they should be completely gone.
Remember to follow directions precisely. Wait to treat Creeping Charlie till after the first hard frost. Don’t get nervous if you see Creeping Charlie start to grow again in the Spring, it should, hopefully, die off. Although I won’t guarantee that! It’s a tenacious weed. Part of me thinks the flowers are very cute and the scalloped leaves add a fun contract to the blades of grass. That’s the story I’m sticking to anyway! And a reminder that this is NOT the time of year to worry about crabgrass or other annual weedy grasses as the first frost will generally take them out.
The other nice feature at this time of year is that our perennial lawn grasses ARE still growing which means they have an opportunity to fill in where you’ve killed the broadleaf weeds. If you use a liquid herbicide you can add a little dishwashing liquid to the mixture. This will help hold the liquid on the leaves longer providing better coverage.
Remember to use chemicals safely, follow the directions on the package, don’t over do it. I had 2 new shrubs killed by a herbicide that a lawn service used.
In late October you’ll want to put down your most important lawn fertilizer application.
