Crabgrass Preventer plus New Seeding Lawn Fertilizer

This products works!!! I applied this product on April 3rd 2020. I also applied Mag-I-Cal and Black Beauty Ultra Seed in the same day. I let Mother Nature water it in. I have seen amazing results. I still have to deal with some broad-leaf issues in the yard, but it looks amazing and you can see results. My neighbors have been asking me what I did and they are now using the product…with my help!

Great product!

This stuff works, I thought it would be all right like other granular weed preventers – but dang it blew crabgrass out of the park. Easily 97% of my lawn is crabgrass free now – perhaps 50% was crabgrass free last summer without use. I live in Minnesota, applied April 21 and it is now early June and the lawn is full of beautiful Fescues, with minor amount of crabgrass/other grassy weeds. As a note: the amount of plantain/broadleaf weeds is maybe 3% of what it was before use too. Will purchase again and add to my lawn care regimen.

It worked! My grass is growing!

You must put this down at the right time of year. You only have about a two week window. Typically you can judge this by when the forsythia is blooming. Basically You need to put it down when the soil is just at the right temperature for seed germination. That’s with corn gluten meal does: it stops seed germination. If you find it’s not working, it’s probably user error.

No crab grass as yet.

Arrived quickly. I have used corn gluten before with good success. Remember that success depends on proper application which means know the square feet of your yard before applying.

Just put it down, so I’lll update later. But be aware that this bag covers 5,000 sq. ft. If you look closely on the product pictures, you can see it at the top of the bag. The description says 1,000 sq. ft.

Great

Absolutely eliminated crabgrass in 2 years.
Now, what to do about the creeping Charlie?

stopped the crabgrass and my own grass did really well

Our yard looks wonderful!

I live in PA (zone 6). I applied this at the end of March, before weed germination. I combined this with organic fertilizer. It is now early May and my yard is very green and I see no weeds/crabgrass/dandelions. There are plenty of yards in my area that are full of dandelions. So, I know it must’ve been effective! My yard looks just as good as the other yards that use expensive chemicals applied by professionals. I plan to apply this in the heat of the summer, and again in early fall.

Works great, just follow the instructions. Everyone around us has crabgrass,… we don’t…. I gave 4 stars instead of 5 because it’s expensive.

Simply the best…..

Yet to see how it does with crab grass.

so far it has worked great with no crabgrass coming up.

I used this product on my newly seeded yard. We live in a developing neighborhood. My neighbor planted his seed 2 1/2 weeks before mine. He used a big box store brand starter fertilizer. My yard has almost caught up to his in terms of height. No crabgrass yes plenty of other weeds as to be expected. It was a hard decision to spend this much money. 100% worth it. I must say that I did not go with Scott’s or any other cheap seed either so I’m not sure which did which but the yard has started nicely, no complaints!

Wish there was more option for organic lawn care. Product works ok but it will take time and you have to be diligent and treat at least a few times a year. I have a big lawn so it becomes expensive to use and you will not see an immediate improvement.

I like this product. I will have to see if it works next Spring, right now it’s hard to tell what it is doing. We haven’t had much rain so I am sure it will take time to work.

It did a GREAT job on my lawn. I live in a difficult area to grow a nice lawn, and there are a lot of lawn weeds very close by, but my lawn got very few new weeds this year, after using this product, unlike last year, without it. I like the product very much.

Huge bag, great price, safe for kids and pets!

I’m not pulling weeds.

Haven’t noticed much by way of killing weeds, but the lawn looks a little healthier. It does say apply more than once, so I’m debating whether to invest more to test it out.

I never had such good results from a crab grass preventer. I’ve tried all different products through the years without even coming close to the same results. I put it down according to the instructions and I have absolutely no crab grass. I am now using everything I need that Jonathan Green sells for my lawn.

did a great job on the lawn. never been greener or thicker. did a better job than the scotts. let’s see how the crab grass part works in the fall.

Incredible product! I didn’t seed at the same time I applied it, but I did rely on it to prevent spring crabgrass germination. I didn’t have high expectations, but hoped it would help a little. Most lawns around me (including directly adjacent to my lawn) are 100% crabgrass. I applied this product in March. My lawn is now deeper green, thicker, and more beautiful than it has ever been (I have used many other products, and none gave results even remotely like this). There was no damage to my lawn and all the areas that usually sprout with only crabgrass have filled in with desirable lawn. Most surprisingly, I cannot find a single crabgrass sprout in my lawn, while the neighbors have full crabgrass lawns that are already blanketed with seed spikes. This is the only product I will ever use again for crabgrass problems.

Great product when you can get two things done at once! Jonathan Green makes great products ! I hope they continue to make great products. They are a little expensive but they are worth it!

No crabgrass, grass seed growing just fine. Working better than I thought it would. I will use it again next year

Both Jonathan’s Grass Seed and Crabgrass Plus New Seeding Lawn Fertilizer exceeded my expectations. First time I used it. Never had much luck at all with Scott’s. I received thick lawn with no weeds. It also helped that we got much needed rain in late April and early May. I live in the Midwest area, Moline, Illinois.

I had my doubts but gave this product a shot this year. So far my neighbors have dandelion farms in their lawn yet only 2 on ours. I’m pleasantly surprised and cost a lot less than the local gardening service.
Update May 15: My next door neighbor uses an expensive lawn care service. Last weekend I saw the neighbor with the lawn care guy going over the lawn. I looked and dandelion weeds proliferating throughout his parkway (grass verge by the street) had sprouted. None in our parkway.
We got a total of 3 weeds. 2 in the back by the garage and one in the alleyway. I’m very pleased with the capability of this product. Just amazed how well it has worked.
Update June 24: Still mainly weed free with only 2 weeds since May 15 update. I’ve spread this out in our patio to try and combat the weeds we keep getting in between the pavers.

Took a chance on something that should be safe for the lawn and the environment. Found this to use on our grass which we just aerated and seeded, and since we live next to a field full of crabgrass, we have been having issues with it invading our lawn. We had used Scotts before on our lawn for over fifteeen years, so this was a gamble. The verdict: worked much better than Scotts as we had no crabgrass whereas with the Scotts, we still had some crabgrass penetration. Highly recommend!
