We really like Speed Zone as it contains the same three active ingredients as the other products, but also has Carfentrazone, which makes it work faster and be effective at lower temperatures. Speed Zone also has a two-week waiting period before reseeding the lawn, compared to the three-week waiting period that most of the other products require. This allows you to get started on your overseeding project sooner so that you will be growing thick and healthy turf.
Most winter annuals can be controlled with just one application of weed killer. However, because perennial weeds live year-to-year with an established root system, some of them may be more difficult to control than others. Clover, for example, can typically be controlled with just one application, while others, such as wild violet, may take several applications to effectively control.
Winter weeds include chickweed, bittercress, henbit and deadnettle, as well as perennial weeds, such as clover, dandelion and wild violets. These winter weeds actually germinate in late September and early October, but they often go unnoticed in the fall when they’re just young seedlings. They overwinter as a small rosette, and come spring they are ready to strike with a vengeance!
Products to Control Winter Weeds
Winter weeds typically flower in March, but can start blooming in February if temperatures are warm! Regardless of when they bloom, you can stop them dead in their tracks with the right control product.
Spring is just around the corner. Before long you’ll be sowing grass seed, applying fertilizer, and mowing the lawn! To return your lawn to a thick, healthy state, March is the time to begin controlling pesky winter weeds currently taking over your lawn, and preventing summer weeds.
Two of our recommended products for Trimec Speed (a new product from Gordon’s for residential use, comparable to Speed Zone, their commercial product), and Bonide Weed Beater Ultra. Generally speaking, liquid weed killers are ideal for controlling actively growing weeds because they typically provide better surface area coverage than granular products. Plus, since they are applied as a spray, they can be turned on or off as needed, limiting waste or overuse.
Regardless of the weed control product you use, none of them will hurt your lawn if they’re used as directed. Be sure to treat any existing broadleaf weeds in the lawn now, so that you’ll be ready to start building a beautiful new lawn from a clean slate.
Many of the weeds we deal with in our lawns and landscapes are not native to North America and originated in Europe or Asia. To farmers, weeds cause more loss and add more costs than dealing with insects, diseases, rodents, birds, deer and other grazers. In fact the number one complaint from customers of lawn care companies involve weeds growing in their lawn.
Controlling weeds is a major concern mainly because of the trait that makes a weed a weed; its ability to out compete with other plants and grow in conditions where most other plants cannot tolerate.
The problem comes from the difficulty in removing them when trying to plant more desirable plants in their place. Weeds will germinate, grow and reproduce through various means much faster than plants that we prefer to grow.
Of the almost 250,000 plant species found worldwide, about 3% or 8,000 plants are considered weeds. They are especially designed to spread quickly, either by wind currents, movement by water, carried in by animals, carried unseen in bales of hay, straw or even on the tires of cars.
The seeds that they spread can germinate if brought to the surface within a couple of years. There are even cases where seeds were found in archaeological excavations that were 100’s of years old and still germinating when planted.
As I was walking my dog during the morning of New Year’s Day, I spotted a dandelion seed head poking through the snow. I found it interesting that this dandelion actually produced a flower in December, but it’s most likely due to some unseasonably warm weather. I think it shows just how opportunistic a weed can be when the weather is suitable for flower production.
According to the Weed Science Society of America, more than 200 weeds have developed resistance to common weed control products. They also stated that more than 240 weed species are reported to be “allelopathic” and produce chemicals from their roots that inhibit the growth of nearby plants.
A weed is a plant that is not only in the wrong place, but intends to stay.

Weeds are amazing plants. In some cases, they are beneficial as they will quickly cover bare ground to keep it from eroding away.
While the northern parts of the US are in the process of hunkering down for the winter, the milder temperatures of the southern states are providing the ideal temperatures to control many troublesome weeds in what soon will be dormant lawns.
The Different Types of Winter Weeds
Winter weeds are probably the most annoying;, they are an annual bluegrass also known as poa annua . This annual weed has two periods of germination. The first period is in the late summer, usually in early September. The second is in late winter/early spring, usually late February to mid-March.
What Are Some Common Winter Weed Control Methods?
Most of these weeds can be treated with broadleaf weed control products, which are available at hardware stores, garden centers and home improvement centers. Lawn care companies like Spring-Green also offer programs that are designed to keep these weeds from becoming a major nuisance in your lawn. In many cases, these weeds distract from the uniform appearance of the lawn and will often overtake the desired grasses.
