What Our Customers Are Saying

What is pre-emergent weed control?

Pre-emergent weed control goes by many names: pre-emergent herbicide, weed preventer, weed-seed killer, pre-weed control, crabgrass preventer, etc.

The purpose of a pre-emergent weed control is to prevent weeds before they are able to germinate. By definition, a weed is any plant that is growing where you do not want it to grow. By applying this chemical at the correct time, you can prevent unsightly and undesired weeds in your yard.

What is included in the service?

The pre-emergent product is either sprayed or spread directly on an area where you’re trying to prevent weeds from growing. The chemical works by forming a barrier on the top layer of soil. It fights the seeds before the weed can actually sprout. The chemical fatally interrupts the seeds growth process in a way that prevents the seed from getting all the way through the germination stage. If you already have visible weeds in your yard then a pre-emergent herbicide isn’t going to solve your problem, but our weed control service will!

The difference between pre-emergent and post emergent weed control is that post-emergent herbicides are designed to attack weeds that are already established and growing. All of the contact weed killers are post-emergents. Post-emergents are applied later in the growing season, after weeds are established but before they have gone to seed.

Weeds can be found anywhere. Therefore you may want to use pre-emergent weed control on mulch beds and in flower beds in addition to your lawn.

Professional landscapers agree that a pre-emergent weed control is the most important part of a weed control system, and that it is the most effective method for preventing many of the most common lawn weeds.

How much does a pre-emergent weed control service cost?

Pre-emergent weed control services start as low as $36 dollars. Lawn Love’s pricing is based on a structured blueprint of your entire property that we create using satellite mapping tools and custom built algorithms. Prices get lower when you bundle a pre-emergent weed control service with one of Lawn Love’s other services, such as lawn mowing or yard clean up.

When should you apply pre-emergent weed control?

The most important aspect of pre-emergent weed control is timing. Early spring and early fall are the most effective seasons to apply. In some cases, you may also need pre-emergent services at other times throughout the year, but since most weeds sprout during spring and fall, this is the best time for prevention.

Early spring pre-emergent weed control

The first pre-emergent service should be completed as your soil begins to warm, that is when to use pre-emergent weed control. Depending on your climate, this could be any time during the year. Usually though, most soils across the US begin to warm in early spring, during March and April.

The best spring pre-emergent weed control is done to prevent summer annual weeds. Summer annual weeds start to appear as soon as soil temperatures begin to warm, usually in early spring months like March and April. Many species continue to germinate throughout the summer. Summer annual weeds sprout, then flower and produce seed, and are then killed by the cold weather of the fall season. These weeds are difficult to manage once they appear. The best pre and post emergent weed control for spring depends on what type of weed you are trying to get rid of.

Spring pre-emergent weed control can help prevent the following weeds:

Early fall pre-emergent weed control

A second application should be done to prevent weeds that germinate in the winter. Winter annuals begin to germinate in the late summer or early fall. Winter annual plants live through the winter to flower, set seed, and die out the following summer.

Some examples of winter annuals are:

Types of pre-emergent weed control products

Herbicides can be classified several ways, and based on your needs and preferences, there are a couple different options of pre-emergent weed control for you to choose from. Ask your Lawn Pro which type of pre-emergent product they are using.

Systemic or contact

Systemic herbicides enter the plant through the roots and leaves and move throughout the inside of the plant.

Contact herbicides kill lawn weeds from the outside in. They attack the exposed parts of the plant, killing the weed by reducing its ability to feed itself through photosynthesis.

Contact herbicides kill only the plant parts contacted by the chemical, where-as systemic herbicides are absorbed by the roots or foliage and translocated (moved) throughout the plant.

Selective or non-selective

A selective weed control means you are selecting the type of weed you want to prevent. The chemicals are formulated to kill certain types of weeds, and leave other wanted plant life alone. An example of a selective herbicide is a pre-emergent weed control designed specifically for the removal of broadleaf plants (leaves that have a flat, relatively broad surface). A pre-emergent broadleaf weed control will remove the broadleaf plants without killing the established lawn in which the weeds grow.

A non-selective herbicide will kill everything it is applied to, even grass! You shouldn’t apply pre-emergent weed control to newly planted grass. The chemicals in some weed controls can damage certain types of grass. If you pick a variety that kills grassy weeds; whether it’s newly planted grass, or seeds from a re-seeding, the pre-emergent weed control will likely kill any new desirable grass seed as well.

For example, if you have Bermuda grass, you won’t want to apply a non-selective herbicide directly to your grass. You’ll instead want to find a selective herbicide that is the best pre-emergent weed control for Bermuda grass.

Common brands of pre-emergent weed control

Organic pre-emergent weed control

It’s hard to imagine that killing a pesky weed can be done organically. However, there are some natural weed control solutions that have worked for those that prefer a more environmentally-friendly solution.

Corn gluten meal is a powdery byproduct that comes as a result of the process for milling corn. Corn gluten has become a common organic and natural pre-emergent weed control alternative to synthetic chemical herbicides. It can be effective to control crabgrass and other lawn weeds.

Corn gluten works when the application of corn gluten is timed correctly, germinating crabgrass seeds will form shoots (the part of the plant that turns into stems and leaves) but not roots, and will therefore die.

Other organic methods for weed control are not considered pre-emergent, but may be a better choice for special uses such as vegetable gardens. These methods include:

How to apply pre-emergent weed control

Pre-emergent weed control services involve active chemicals, and can be harmful if not handled properly. If you are just starting out with lawn care, and have never used active chemicals before, you may want to consult a professional pre-emergent weed control company. Lawn Love professionals know how to apply the chemicals safely, with your yards and family’s best interests at hand.

The first thing you need to do is determine what types of plants, weeds included, are growing in your yard. You need to know what type of grass you have, so you can prevent damage from the chemical application. You also need to know what type of weed is growing, so you can choose the best solution to prevent it. Search the internet, or take a sample into your local home and garden store to determine the plant type.

Read labels, understand the chemicals, and ask for help if needed. Some of the chemicals are designed to kill grass weeds, while others work best on broadleaf weeds. For example, if you have St. Augustine grass, you’re going to want to choose a St. Augustine pre-emergent weed control solution. This is why you have to know which types of plants are in your yard, and which types of chemicals kill those specific plants. The best pre-emergent weed control is going to be specific to the types of weeds growing in your yard.

Choose between liquid or granular pre-emergent weed control. The application type you prefer can depend on your personal preference and on your location. If you choose granules, then you’ll have to follow up with watering the application location. This can be done from the rain, so you could time application with the weather. Pre-emergent weed control liquid has to be mixed with the right amount of water, then applied using a pre-emergent weed control sprayer.

The best pre- and post-emergent weed control is one that incorporates all of the above.

Safely applying pre-emergent weed control

You can choose the best pre-emergent weed control products, but if you’re not applying them safely, they won’t work and even worse, could harm you. When deciding between selective or non-selective pre-emergent weed control products, you have to read the label of your chemicals to know what you’re applying. You also have to know what type of grass and other plants are growing in your yard, so you don’t purchase a chemical that will kill them.

Also, it is extremely important to closely follow the included instructions, including those for use, safety, clothing, protective gear, storage and disposal. Failure to follow instructions can increase the dangers associated with use of the chemicals and decrease their effectiveness.

Keep contact with the chemical to a minimum, this includes keeping pets and children away from the area for an extended amount of time. Safety should be everyone’s number one priority, so you may want to consult a professional in regards to application.
