Reddit reviews SpeedZone Southern Broadleaf Herbicide for Southern Turf-1 Gallon 7153871

Haha sorry!

So you do have grass there. It's dormant from the cold. Now is the time to prepare it for the transition to summer. The best offense against the weeds that come with summer is a good defense. A pre-emergent, like the name suggests, stops weeds before they have time to emerge/germinate. A weed control, also known as a post-emergent, is used to control the weeds that are currently visible.

The active ingredient in this product is Atrazine (always check the package label to make sure Atrazine is the listed active. Image for nuts edge is imazaquin which is not what you're looking for). It is a dual purpose herbicide that prevents and controls weeds to come and those visible. You can purchase it in a garden hose attachment form which makes application easy.

This is a pretty good tutorial. He's spraying ppre emergent but you can substitute any herbicide or pesticide. Measurements are key to a successful application. Measure the area of your backyard. If you have a 4,000 soft back yard, and the product calls for 1oz/1000 sqft, then you know to mix and apply for 4oz of material. Sometimes you'll see 16oz/acre ~ 16oz/44,000sqft ~ .4oz/1000sqft ~ 1.6oz/4,000sqft.

While Atrazine does a good job, it does not do a great job, and it is not your only option. Were it my lawn, I would use a half rate of Atrazine + a regular St Augustine rate of speed zone southern.

The Speedzone will catch more weeds that Atrazine will leave behind. And for a pre-emergent, I would use Barricade ( Prodiamine).

You can purchase it in WDG form (water dispensable granules) which allows you to dissolve it in water, mix, and spray it, OR you can apply it as granular with a spreader. You can buy it for a very high prices in flowable liquid form as well. Anytime you can spray pre-emergent either with WDG or flow able form, you will get consistently better results than granular.

One application of these three products will have you in the right direction. Mid May I would fertilize with a slow release fertilizer with iron (4.0% or higher iron content. Check the bag for percentages). You're safe to use a higher nitrogen blend like a 24-4-8 or a 34-0-4. The important aspects will be the iron and the slow release. You want to apply this at 3-4lbs/1000sqft.

Let me know if you have anymore questions. By the way repeat the pre-emergent process come September. You'll need to do pre-emergent applications every fall and spring otherwise, see original lawn photos.

Here, this one is safe for Bermuda
