## Description

desertcart.com : Jonathan Green (11970) Blue Panther Kentucky Bluegrass Grass Seed - Cool Season Lawn Seed (3 lb) : Grass Plants : Patio, Lawn & Garden

Review: Wow! Great seed with no weeds! - I am very particular when it comes to my lawn. I have seeked out some KBG at my local big boxed stores only to come up empty handed. A lot of them had weeds and or other types of grasses I wasn’t looking to put in my lawn. The quality is far superior than what I have previously got from home stores. The value for what I got was a little more than I expected to spend, but the results are quite phenomenal. The seeds are very tiny , so you’ll need to be very careful how you’re spreading it. The seed does take quite awhile to germinate, around 3-4 weeks, but to me, it’s worth it. The grass has been coming up in abundance. It is growing exactly where I planted it. Very dark green bluish color. I was hesitant because I was getting such a small amount of seed for the price, but that’s how Kentucky Bluegrass is. I would highly recommend this product. Very good seed without weeds! Just keep in mind that it will grow slow. Be patient. It is worth it. I would and have bought more from this supplier and the same seed, because I like consistency in planting great grass. Don’t hesitate just get it. You will not be disappointed.
Review: Absolutely the most beautiful blue grass. - Absolutely the most beautiful blue grass. Lush carpet like grass thick and sturdy. Germinates in about 7 days in Virginia.
