Upgraded Crabgrass Program for 2020


Note: If you prefer not to read this entire paper, please skip down to the heading, “What is Green Giant Doing to Provide Better Crabgrass Control?” and read from there to the end.



Over the last several years, crabgrass populations have exploded and it has caused a lot of problems on lawns.  The main culprit is excessive rain and warmer weather throughout the entire growing season.

In 2017 and 2018, we had rain all year long. In both of these years, there were no rain-free periods where the soil dried out.

In 2019, it was also very wet until late July / early August. By this time, the crabgrass plants were mature – the damage was already done.

These conditions enabled crabgrass seeds to germinate (sprout) all year long.


How is Crabgrass prevented?

Crabgrass grows from seeds each year. Therefore, the best way to control crabgrass is to use a “crabgrass preventer” application.

A crabgrass preventer kills the seeds when they begin to grow.  We primarily use a preventer called Barricade because it lasts longer than other products. Barricade will only kill seeds – it cannot kill crabgrass plants that have already begun growing. Barricade is supposed to give 3-4 months of control, but there’s more to the story…

Sunlight, rain, and naturally occurring micro-organisms in the soil breakdown crabgrass preventer over time. So, as the season goes on and we get to the 2nd, 3rd and 4th months, the material becomes less and less effective.


What has Changed?

In what we used to consider “normal” weather patterns, the crabgrass preventer worked pretty well. But, that “normal” weather pattern should consist of the following:

  • A wet, warm spring
  • A dry, hot summer
  • Mild, wet weather from mid-September until the first hard frost (which kills crabgrass, usually in mid-late October).

In this weather scenario, the crabgrass preventer primarily ‘earns its keep’ in the wet, warm spring – at the time the preventer is most effective. This is a perfect match-up – when the seeds are sprouting like crazy, the preventer is at its maximum strength – and it works like a champ!

However, in more recent years, when we expected hot, dry periods, we have ended up with very wet conditions, and the crabgrass preventer just can’t keep up. By late-spring and into the summer, the material is degrading and, at the same time, crabgrass seeds are still germinating at a furious pace.


What is Green Giant Doing to Provide Better Crabgrass Control?

Our lawn care programs have always included one treatment of crabgrass preventer in the early spring – using Barricade. We will now be applying a second crabgrass treatment 5-8 weeks later with a product called Dimension.

Dimension and Barricade are considered to be the best crabgrass preventers available, but there are some differences.

While Barricade lasts longer than Dimension, Dimension has the ability to kill young crabgrass plants after they sprout (in addition to killing seeds that have not yet germinated). Adding the Dimension treatment should dramatically reduce crabgrass problems through the summer months. This is the 1-2 Punch that crabgrass desperately needs!


How much does it cost?

We have decided that we will provide this service at cost for the additional material – with no mark-up. On your enclosed renewal notice, your Lawn Care – Round 2, price includes this additional charge.

We are making this as inexpensive as possible because we want your lawn to look as good as possible. 


Do I have to get the additional treatment?

No, you don’t – but please read about our guarantee below so you are fully informed.

If you DO NOT want the additional crabgrass treatment, please contact our office as soon as possible. Otherwise, we will provide your lawn care program as shown on your enclosed letter.


What is the Guarantee?

Dealing with nature is never perfect and, it is possible, even likely, that you will still get some crabgrass in your lawn.  Nevertheless, if you are on a full Green Giant lawn care program, and receive both of our crabgrass treatments, we will treat any crabgrass that grows in your lawn, at no additional charge.


Why doesn’t Green Giant provide a guarantee if I only get one crabgrass preventer application?

The answer is, crabgrass cannot be consistently controlled with only one application. And, we cannot guarantee something that we cannot control.


Please contact us with any questions or concerns and, Thank You for doing Business with Green Giant!
