## Description

desertcart.com : Jonathan Green Fast Grow Grass Seed - Cool Season Lawn Seed - 15 lb | Quick-Turf for Problem Areas, Germinates in 7-10 Days : Grass Plants : Patio, Lawn & Garden

Review: Grows so fast! - I LOVE this grass seed. 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: It works! - I wasn’t quite sure what to expect as the reviews for this product. Summer are good in summer bad however personally I have had nothing but good results as the color is bright green and there is lots of grass that has come up after planting. Yes, it did take roughly Close to a month for the grass to grow as thick as it as grown, but I am very pleased with my results. You will see in the two pictures on the left-hand side. I did not plant grass there however, on the right hand side, the grass is full where I planted grass. The grass is a little spotty, so I will be planting more however, I am happy with what I have so far. I am located in Fort Worth, Texas, and this product has worked for me.

### ⭐⭐⭐⭐ Great at growing fast, but I couldn't get it to last
*by A***L on June 22, 2014*

I love this grass. 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 :(
