Stop Crabgrass Before It Starts.
If you’ve ever battled crabgrass, goosegrass, poa annua, or other invasive weeds, you already know — once you see them, it’s too late.
Safeguard 0-0-7 with .37% Prodiamine creates a powerful barrier in the soil that prevents weed seeds from germinating in the first place. The result is a cleaner, thicker, weed-free lawn without constant spraying or hand-pulling.
This is the same professional-grade active ingredient trusted by lawn care operators, now available for your home lawn.
Apply before soil temperatures reach 55°F in spring, or in early fall to prevent winter weeds. Timing is everything with pre-emergent control.
Safeguard contains 7% potassium (potash) and no nitrogen.
If you prefer nitrogen with your pre-emergent, consider Guardian 13-0-10 Pre-emergent Lawn Fertilizer instead.
Application Rate: Apply at 4–5 lbs per 1,000 square feet using a broadcast spreader.
Watering: Water in with ½ inch of irrigation or rainfall within 7 days to activate the barrier.
Important: Do not apply if you plan to seed. Prodiamine prevents all seeds from germinating, including grass seed.
Spring Application: Apply before soil temperatures reach 55°F for 3–5 consecutive days.
Fall Application (Warm-Season Lawns): Apply in early fall to prevent poa annua and winter weeds.
For season-long protection, apply twice per year.
If you want a clean lawn without fighting crabgrass all summer, Safeguard 0-0-7 is the first step.
Apply it on time. Water it in. Enjoy a weed-free season.

Review topics: [].
"Put safeguard down in late March when soils temps were 57 degrees, and in the past 2 weeks have had more clover pop up then ever before. Lawn did look lush after applying though, just didn’t do a great job keeping weeds from germinating."
"Unfortunately, I was not happy with this product. I put this down twice, once in October and another time in early March. My yard had more weeds then it ever had this past winter. When I contacted support, I didn't get helpful feedback. My neighbor who now uses your product after I recommended you, had the same issues. It was very discouraging to look at our neighbors yards and not have these issues."
"I ordered my Spring Fertilizer with Pre-emergent. The lawn is very noticeably green and lush. . . but it is still April. so In June, when the crabgrass flourishes, I will tell you how pleased I am. I do plan to do my June, weed and feed from Synergy."
"Put it down about 3 weeks ago and my lawn never looked better than it does now, used Scott’s weed and feed for years and there is no comparison, love it!"
"We are disappointed in the results. I applied it 3 times since October and I am still spraying for way too many weeds. The product did not perform well at all."
"Excellent product! My zoysia grass has greened up quicker than most other yard in the neighborhood and I've had very few weeds to co tent with this Spring. Highly recommend."
"Did not seem to make any difference. The Scotts I used last year worked much better. Now I am having to use Atrizine to treat all the weeds coming up."
"After two years using scotts, etc. , I used your pre-emergent product and my centipede lawn has almost fully recovered. I also used Celsius for visible weed control. Most stores products contain way too much nitrogen and not enough potassium for centipede. Now I will only buy your products."
"Product delivered today will use before the weekend looking firward to a healthy lawn"
"Poor results"
