Faster working Grass seed

Would Recommend

[This review was collected as part of a promotion.] I have to say just after a week and a half of putting the grass seed on some spots in my yard I noticed grass that quick. I would highly recommend this product compared to other grass seed mixes I have used in the past. Overall great product!

I would definitely recommend and purchase this again

Would Recommend

[This review was collected as part of a promotion.] I have had a great experience with this grass seed, I have some areas were I just couldn't get the grass to grow and if it did it was like an all weeds . So , I gave this a try and sure enough it is doing good so far, the seeds have this coating on it and I think it makes a difference as far as the thickness and quality of the grass once germinated. I would definitely recommend and purchase it

Not great once summer heat showed up

Would Not Recommend

I planted in spring after spreading topsoil over bare spots. The seed germinated and the grass came in good. Everything looked good through the end of June here in SE Michigan. By the end of July the grass drying out and thinning. I would not recommend this product as a long term solution. I would like my money back.x

It was very hot and dry in the south

Would Recommend

[This review was collected as part of a promotion.] We had a terrible heat wave and no rain. This seed struggled to take. I would water the spots I treated but they were in full sun and the seed struggled to grow. In the one area I had treat that was partial shade, it grew better but still lacked the fullness I was aiming for. It would probably be better suited to a more favorable, mild climate.

I had to wait to leave a GREAT review.

Would Recommend

[This review was collected as part of a promotion.] Hear me out. You have no knowledge of grass, when yo grow it, where to put it, how to spread it, if you need to water it etc. Well...that's me. I'm new to home ownership and I had quite a bit of bald patches around my yard. I followed the instructions on the bag and now I have lush grass that doesn't hurt when we run around barefoot. It took about a solid month before it fully came in, but BOY did it. It's so thick and beautiful. Now I feel lik...

This was so easy to use

Would Recommend

[This review was collected as part of a promotion.] 3 basic steps that even I couldn't mess up. No mixing with top soil, no rototiller, just a rake and water.

Can see growth a little growth

Would Not Recommend

[This review was collected as part of a promotion.] I spread the seed in multiple areas that needed grass. Sun was plentiful in some areas, shaded in others. We received a lot of rain over the past few weeks, so I was hopeful for good rooted blades of grass to shoot up once the sun came out. I am seeing some grass growth, but it's sparse. Maybe it's bad luck, maybe it's too much rain, maybe it dried out when the sun came out, but I'm not impressed with what I'm seeing.

Would buy Penninton grass seeds again

Would Recommend

[This review was collected as part of a promotion.] Works great. Had to wait 2 weeks, because hubby was determined he would do the seeding. Did not take long to actually place in the needed spots. We had rain off and on, and where the ground was level it filled in nicely. I think some of the spots that were on the hill were washed down, and filled in the areas below them. lol. Still grew some lovely grass. It is very true that you need to plan on at least 4 weeks for it to fill in the areas, but...

[This review was collected as part of a promotion.] Took a while to take but it grew up in the patches. Nothing remarkable but it did grow.
