I’ve ordered it three times now as we built from raw land so everything around our home was nothing but dirt when we moved in. New growth started popping up within a week and 1.5 years and 3 bags later we have a fully covered acre of grass. To be honest, I didn’t even do much prep work as all I had at the time was a garden rake which I used to puncture the ground where I spread the seed (using a manual hand spreader) but it still did perfectly well! Photos are after 2-3 months Review: Bought some more and will definitely buy in the future. - I wasn't expecting much but this worked great. I had a pool put in last summer turning my yard into a big mud slide. I temporarily put fake grass down on most of it. But this summer I wanted to see if I could get some grass to grow. I have a lawn guy, but I still have a deck to do so I decided to give this a try and he could do his magic if it didn't work when he starts his service later this month after the deck is up. I must admit I didn't follow many of the directions. I just sprinkled some seed a couple of weeks ago when I knew there would be a rainy week. Other than the rain the weather wasn't great, we were going from 80 degrees all the way down to 30 some nights. I figured if it didn't work I can try again. I only did about half my yard to see how it does. Two weeks later and it's growing nicely almost everywhere except for a couple of areas with really compacted clay soil. Did I mention we have horrible soil? I had another bag so I aerated those spots and raked some top soil in before I sprinkled more seed. I also added seed to more of my yard except for the area where they will be working on my deck. I am more than thrilled with the result. Excited that this year I'll have grass in my yard again. ## Features - QUICKLY GROWS TURF - This rapidly establishing grass seed mixture grows quick-turf for problem areas.

Thank you** A: The question you should have really asked yourself is why is nothing growing in this area? If even weeds will not grow, then you may have pH problems or other issues that would make growing a desirable turf more difficult. This would be a good option if you need quick coverage assuming the soil is in good enough condition to grow grass, but as other said, this is an annual seed. If you plant it in the fall, it will over-winter and persist through the following season. If you plant it in the spring, it will die off at the end of the year if I understand correctly. If you want seed that persists season to season, get a perennial type seed. I strongly suggest researching grass types and seeing what will grow there based off of the amount of sun and shade you get. Also, if possible, I suggest looking at turf types that spread via stolons and/or rhizomes so they will self-heal without the need to reseed dead patches. This way when you have a weed in the lawn and kill it, the desirable lawn will spread into the area where the weed was and take that space over. The #1 defense against weeds is a thick and healthy lawn, and self-healing types of turf are great at this and help to reduce future weeds. **Q: Can I just spread the seed or do I also need to buy compost or fertilizer?** A: Here' what I did:1. The soil was prepared by using a manual cultivator to loosen the top layer of soil.2. The seeds were spread by hand along with starting fertilizer.3. I then used the manual cultivator to bury the seeds and fertilizer.4. I covered the freshly planted soil with a straw/hay blanket to protect them. (from the birds that feasted on them the last time)5. The soil was watered once daily. Considerable new spouts were visible on day 5....and continued growth daily.Now....If i can figure out how to keep these nuisance geese from devouring my hard work I know i will have a beautiful lawn in no time.Although the geese constantly eat the shoots down they continue to slowly thrive....PS: Any tips on how to keep these geese off my lawn? **Q: What is the exact composition of the seed mixture would be a basic query of any reasonable customer.** A: I am not being sarcastic in my response. I know nothing about growing crops, plants, fruit except to "stick in the ground and water it and let it get sunlight." I had a friend who I thought gave me sage advice: the plants don't read the books. So, as far as planting, I just grab some seed, chop the ground a bit, throw the seed in and VOILA! up come grass, thick, beautiful grass. Wish I could show pics. I have neighbors who told me that the grass wouldn't grow because the water would run off, so I needed to build some kind of thingy mcbeanie or whatever. I paid no attention to that mumbo jumbo, did what I described above and now their all like, "WOW! The grass is beautiful!!!" **Q: Will this grass grow in section 9 in the south?** A: By no means I'm I a grass expert. However I live in Newton,Mass. and this stuff really grew well here. That's my experience, hope it helps. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Grows so fast! *by J***R on August 7, 2026* I LOVE this grass seed.

Anyone who says it's not growing is doing one of two things wrong: 1) not watering it multiple times a day, 2) not putting a 1/4"-1/2" layer of soft dirt over the seed to hold it down. I bought one bag at first and tried it out on a few different areas and once I saw it was successful I bought a second bag. I noticed that if I loosen up the dirt before putting the seed down, and then put dirt on top of the seed, sprouts will appear within a week or so. If I don't do those things, and I water for a week straight, they won't pop up, but then I pile dirt on those areas and the next day I can already see a tiny sprout. I have seen it done a different way - put the seed and dirt in a wheelbarrow and mix it all up, then pour it over your yard. I haven't tried that so I don't know if that works as well or better. I just keep doing it the way I explained above and it works great for me. The only problem is I don't really know what I'm doing...like when to seed, how much shade or sun it really can take, and how it will survive in hot climates. I live in Phoenix and I planted it around spring time but by the middle of summer ALL of the grass I planted was dead. I probably did something wrong, or Phoenix was simply too hot for this grass even though I watered so much that my water bill was sky high. I guess I'm stuck with Bermuda :( ## Frequently Bought Together - Jonathan Green (10840) Fast Grow Grass Seed - Cool Season Lawn Seed (7 lb) - Scotts Turf Builder Weed & Feed3, Weed Killer Plus Lawn Fertilizer, Controls Dandelion and Clover, 5,000 sq. ft., 14.29 lbs. - Scotts Green Max Lawn Food, Lawn Fertilizer Plus Iron Supplement for Greener Grass in 3 Days, 5,000 sq. ft., 16.67 lbs. --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.is/products/6078012-jonathan-green-fast-grow-grass-seed-cool-season-lawn-seed](https://www.desertcart.is/products/6078012-jonathan-green-fast-grow-grass-seed-cool-season-lawn-seed) --- *Product available on Desertcart Iceland* *Store origin: IS* *Last updated: 2026-09-09*
