Click below to listen to my Garden Bite radio show: Fall herbicide care
This is the last week to put down a herbicide for those broadleaf weeds. These plants are actively growing right now so it’s a good time to get at them. The 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. I kind of like the wild violets and generally let them go, but oh, those irritating dandelions!
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. In late October you’ll want to put down your most important lawn fertilizer application.
