Spring is the time that Broadleaf Weeds become a problem in lawns. As the soil temperature rises the weed seeds in the soil germinate. Weeds are considered pests since they stick out in a beautiful lawn setting.
First, let’s identify what a Broadleaf Weed is. Broadleaf Weeds tend to have multiple leaves and some have flowering characteristics. Broadleaf Weeds are not grassy weeds. In early Spring the first Broadleaf Weeds we see are Wild Onion and Chickweed. Wild Onion stands straight in clumps around the lawn. These weeds are perhaps best controlled with a spot spray since it is hard to get a granular product to stick to the weed for effective control. Wild Onion tends to disappear once mowing and maintenance begins.
Chickweed is a prostrate Broadleaf Weed that appears early in the Spring before the lawn starts to grow. My nine-year-old daughter likes to pick the white flowers that the Chickweed plant produces, creating a bouquet for my wife. However, most people think of Chickweed as an objectionable weed. Chickweed tends to become less of a factor once the lawn starts to grow along with mowing and fertilizing.
Dandelions are the best-known Broadleaf Weed because of their bright yellow flower, and ‘puffy’ seed balls. Dandelions appear in late Spring once warm days arrive. They are very persistent. Dandelions are a perennial weed; they can be controlled both in the Spring and the Fall like many other Broadleaf Weeds. Other common Broadleaf Weeds, which are found in many lawns, include Clovers, Plantains, Oxalis, and Spurge.
Weed controls have been developed which are selective. This means that you can apply them to established lawns without killing the desirable grass. There are a number of granular or liquid products available to control weeds. An excellent choice of weed control is Jonathan Green’s Lawn Weed Control. Certain Broadleaf Weeds are harder to control and may require more than one application at 30 days apart. Jonathan Green Weed and Feed is labeled to control over 250 different Broadleaf Weeds!
Many granular lawn weed controls are available both with and without fertilizer. Jonathan Green’s Weed and Feed includes a weed control and fertilizer combination. These products are the widely used since they can do two jobs at the same time: control weeds and fertilizer your lawn. Granular lawn weed controls are used if you do not want to fertilize or have fertilized the lawn area in the last four to five weeks, like Jonathan Green’s Lawn Weed Control. Granular weed controls work because the weed control sticks to the leaves of the weeds. The control then translocates into the roots of the plant, killing the weed. Quality granular products will contain smaller particle sizing. This allows the weed control to stick better to the weeds providing better control. Granular products can be applied with either a Rotary or Drop type spreader, both available through Jonathan Green.
There are certain tips that you should follow to insure effective weed control. Broadleaf Weeds are best controlled when they are actively growing during Spring, Summer and Fall months. Controlling Broadleaf Weeds during cold months generally fails. Do not mow your lawn 2 days prior or 2 days after application. Apply granular controls, like Jonathan Green’s Weed & Feed Lawn Fertilizer, during the early morning hours while there is dew on the lawn or sprinkle the lawn prior to applying granules so they stick to the weeds. Do not apply Broadleaf Weed controls if rainfall is expected 1-2 days after application. Do not sow grass seed for 3-4 weeks after your weed control application. If you have seeded your lawn wait until you have mowed the lawn twice before applying any weed controls.
Remember, Broadleaf Weed controls may take 3-4 weeks to get to the root of the plant so be patient. Be sure to apply the proper amount to your lawn area in order to avoid injury to desirable turf. Read the label and contact your local garden center or hardware store or extension agent if you have certain questions about weeds in your area.Back
