Broadleaf Weeds; What Are They and How Do Herbicides Kill Them?

Ground Ivy Broadleaf Weeds; What Are They and How Do Herbicides Kill Them?

What Are Broadleaf Weeds?

Broadleaf weeds are weeds like Plantains, Chickweed, Clover, Ground Ivy, and Dandelions. They are a classification of weeds that are not grasslike, and are therefor more susceptible to a different set of chemicals than lawn grass is.  They can be perennial or annual, and treated to removal by hand, with tilling, selective spray of an herbicide, or a broadcast chemical.

Toxic chemical usage should be the last method of control whenever possible, however, and depending on the spread of the weed in question it may take from two months to a year or two to control the spread of it due to fallen seeds, and re-growth from the roots.

Broadleaf weeds can be treated by:

Broadleaf weeds can be treated by natural horticultural oil, herbicidal soap, selective weed-n-feed herbicide, systemic herbicide, and non-selective herbicide. Pre-emergent herbicide also works well to subdue growth of any plant before the growing season.

Herbicidal soap, Horticultural oil, weed-n-feed, systemic herbicide, and non-selective herbicide all attack a plant that has already leafed out, and is already out in the lawn.  Some of them merely smother the plant, or damage the leaf tissue that they are applied to, others like the systemic herbicide are ingested by the plant, and flow through the plant’s entire system before killing it. Pre-emergent herbicide works by creating a barrier on the soil that prevents seeds, grass, and weeds from sprouting up from the ground, and they inhibit all growth of immature plants.

Where Can I Find Products To Treat Broadleaf Weeds?

Products that treat broadleaf weeds can be applied by a lawn company to avoid over-application, or by yourself as part of a DIY program.  The easiest treatment to come by is Round-up, which will kill anything on contact, but is not selective.  Round-up can be purchased anywhere from a home and garden superstore to your local Target.  The next most popular products are weed-and-feed granuals and liquids from Scotts, including their “Turf Builder Winter Guard” program, and their fall “Weed and Feed.”

If you want to use a Horticultural Oil, I suggest checking out Planet Natural’s Bonide “All Season, Horticultural and Dormant Oil,” which can be used year-round, and is safe for people and pets, biodegrading naturally into the lawn and garden.

What To Consider Before Application:

If you opt to use a chemical program on your yard, makes sure you carefully read the label on the bag first before purchasing it, or consult with a lawn specialist in your local garden center.  Several products on the market are created for one or two types of lawn grass, and can harm the most common lawn grass blends.  Check carefully to ensure that the program you choose is designed to work with the lawn you have, and with the grass common to your region.  Most North American lawns are comprised of a mix of Bluegrasses, and Fescues, and Rye’s, and not all Scotts products are designed to protect those blends.
