Frequently Asked Questions

All products we use are approved by EPA. We are also under the regulation of the Tennessee Department of Agriculture. There should be no concern assuming all label guidelines are followed as directed.

We advise staying off the lawn until the application is completely dry. All products applied are regulated by EPA and if label instructions are followed properly, there should not be a problem. However, your family does need to stay off the lawn at least until the application dries. We recommend at least a couple of hours. Same applies for your pets.

We recommend waiting at least 24-48 hours before and after the application before the lawn is mowed. We discourage bagging your clipping unless the lawn has excessive thatch. Clipping are beneficial because they restore nutrients back into the soil.

Herbicide activity is often affected by two things. First, temperatures will determine how fast the plant takes in the herbicide. The cooler the temperatures, the slower the weeds will respond to the application. In cool months, it is not uncommon to take 3-4 weeks to visually see the results of the application. In the summertime in may be seen in just a few hours. Secondly, conditions play a very important role as well. In dry conditions, the plant will go more into a dormant state and its pores in the leaf tissue will close. Therefore, herbicides will not be absorbed and no control is achieved. Once there is rainfall or irrigation, the plant opens back up its pores, and herbicides, if still available, will be taken in and do their job.

Remember, the best weed defense is a healthy, thick stand of grass. Our lawns need up to 3 feedings throughout their growing season. Our goal is 1 lb of nitrogen per 1000 sqft unless soil analysis calls for a different blend.

Keeping your lawn weed-free is both a science and an art. Each yard is unique and may require different, and multiple, applications techniques to achieve the results we all want. Please understand that one application will help, but obviously not completely eradicate your problem. Therefore, multiple applications may be required for your lawn to reach its full potential of becoming weed-free and healthy.

Most of the time, that’s great! To provide maximum performance every application requires irrigation for the plant to use the products that are applied. It can be in the form of either rainfall or irrigation by the homeowner. However, it there is an unexpected heavy shower to appear as the application is applied, it can affect the weed control. If there are concerns, reach out and we will stand behind our work. If the application has time to dry, it will be fine.

That is a great question. The answer is now. Even though Pre-Emergents are important in your weed control strategy, as too is feeding (fertilizer) the lawn for color and turf density. The best weed defense for lawns is a healthy and thick stand of grass. The fact is, the sooner you start, the sooner you will get your lawn to reach its potential.

Some weeds are more difficult to control than others. A general rule of thumb is that perennial weeds (tend to live for several years) are more difficult to control than annual weeds (come back year after year.) The pre-emergent applications we apply help prevent weeds from germinating. However, pre-emergent applications are not effective on certain weeds such as Nutgrass and Dallisgrass. These types of weeds require post-emergent applications to control and can be very difficult to eradicate completely.

That’s a great question. Timing and selection of herbicides are vital for the success of a weed management strategy. There are many products available for licensed professionals. Some products do better on some weeds than others. At 4-Evergreen, we note and monitor conditions on the lawn to help provide us with the right strategy for your lawn. Here are the most common Tennessee weeds that are difficult to control and what our strategy is with them.

Cool Weather Weeds

• Poa Annua: Poa Annua germinates a lot sooner in the fall as do other weeds. Early Pre-Emergent in late August will help in germination. Poa Annua has developed known herbicide resistance to Simizine and Round-Up. This weed is active in fall, winter, and spring weed.
• Star of Bethlehem: This weed germinates in the fall and stays active in the same areas year after year until summertime temperatures arrive. There are no Pre-Emergent’s that totally prevents germination. There are Post-Emergent’s available for its control and they are more costly. Digging up is sometimes the best option.
• American Burnweed: (aka Fireweed) Fireweed germinates in early spring and can easily be controlled once it is up. Unfortunately, the seed of this weed stays in the thatch layer, where it germinates, and usually, the Pre-Emergent applied gets below the area of germination. Spraying or hand pulling (very easy to pull up) are the best ways to get rid of them.

Warm Weather Weeds

• Dallisgrass: Dallisgrass is a perennial and is very difficult to control. MSMA was a better product for many years to use but is no longer available to lawn care professionals. There are other alternatives but they are costly and require multiple applications to control.
• Goosegrass: This weed germinates later in the spring, a few weeks after crabgrass. Pre-Emergents may help but not totally take care of it. It generally grows in compacted soils so aerating the lawn will help. MSMA was a great product for many years to use but is no longer available to lawn care professionals. There are other alternatives but they are costly and require multiple applications to control.
• Nutsedge: This weed produces underground bulbs and only a select few Pre-Emergents will help in its germination and they are costly. Post-Emergents are available for control. This is a summertime weed.

All products applied are regulated by EPA and if label instructions are followed properly, there should not be a problem. However, pets do need to stay off the lawn at least until the application dries. We recommend at least a couple of hours. Same applies for you and your family.

Prior to having core aeration performed on your lawn, please remove all lawn furniture, toys, and other moveable objects from your yard. Additionally, to prevent damage from occurring, please inform 4-Evergreen during the time of your scheduling if you have any of the following in your yard: irrigation heads, valve box covers, drainage pipes, shallow electrical lines, invisible fence, and any other sub-surface object(s).

All products we use are approved by EPA. We are also under the regulation of the Tennessee Department of Agriculture. There should be no concern assuming all label guidelines are followed as directed.
