Tips for Lawn Care Success
First, regular feedings help your lawn look it’s best and provide the nutrients it needs to withstand the stresses of weeds, weather and activity.
Secondly, after you mow leave the grass clippings on the lawn! This allows grass to use water more effectively. Finally, water; utilize nature’s sprinkler as much as possible. When you do have to water, do it between 6 and 10AM - less water is lost to evaporation and more reaches the roots.

Used correctly, a pre-emergent weed control such as this one is very effective. This means applying at the prescribed rate and on time - two weeks before soil temperatures are warm enough for crabgrass seeds to germinate. Blooming forsythia is a good indication that it is time to apply this product. So why this product versus what you can get at your local big box store? Well, big box stores carry weed and feed products for the most part versus a pure pre-emergent, and early spring, while a good time to apply pre-emergent, is not ideal for fertilizer application. Fertilizer is best used when grass is actively growing; in spring, this tends to be more than a month after the ideal time to apply pre-emergent. The best resource I can recommend for the correct times to apply pre-emergents and fertilizers is your local university extension and co-op. In Wisconsin where I currently live, a single early spring pre-emergent application around mid April tends to be sufficient. When I lived in Southern Indiana, with warmer summers and a longer season, I found that I needed split applications six - eight weeks apart.
One other small point to conclude this review; a healthy lawn is the best defense against weeds of all kinds; very few weeds, including crabgrass, can out compete an aggressively growing turf grass such as Kentucky Bluegrass. Most issues tend to occur when the lawn is stressed, such as during periods of drought, and a pre-emergent will keep crabgrass from taking over your lawn during these periods.
A product like this is becoming increasingly hard to find, with many companies pushing combined weed and feed products for convenience. I am glad Amazon carries this and hope they continue to do so in the future.
Cornell is one of the top agricultural universities in the world, and it says to wait until soil temperatures warm up. The exact paragraph from the site says: "Crabgrass germinates best at 59F to 65 F. So wait for soil to warm before applying pre-emergence crabgrass control. Soil in thin or bare spots warms up sooner. Reseed these spots in early spring, or be prepared to apply crabgrass control earlier than for the rest of the lawn."
I now apply this product after we get one full week in the mid sixties. It works wonders. Highly recommend this product, especially this one without fertilizer, because you can get down the spring fertilizer a couple of weeks early to give your lawn a head start, then stop the crabgrass just when it wants to germinate. This double whammy of strong grass plus depressing crabgrass growth really took my lawn to the envy of the neighborhood. Amazing what a little science and research can do.

If you don't put this product down before the ground temps (not air temps) reach 55° for some weeds it's not going to work. In my area mid FEB is usually good, but I may switch to early FEB in the future to ensure I get it down before ground temps reach 55°. This product will do anything in the middle of summer. It works best at a very specific time of seed germination in conjunction with ground temps and that differs based on where you are in the country.
Use this web page to find out what the ground temps in your area are. Just open and put your zip code in the search bar. That's it.
Also, I recommend using this product in mid to late Fall if you are prone to grassy weeds. This is the only time it's effective for poa annua or similar weeds. I've been using two treatments in the fall and one in the Spring for the past two years. With a few other fertilizer treatments and 2,4D, my lawn has never been better!
