Reviews

I had seeded in the

"I had seeded in the past and couldn't succeed. I wanted to try the seeds how it will work. Now, I love the seeds as well as your products. I get compliments from people. 👍"

— Minako H. (5/5)

Mixed results

"First time I used a small bag I had decent germination. Next time I purchased a 25 lb bag and put a large effort into prep. and received very poor germination. I also gave some of the same seed to my neighbor and they complained of the same thing. Disappointing because now its too late to do anything else."

— js (3/5)

Great expectations

"Have been taking care of my lawn and converted it to a small soccer pitch. Needless to say it needs intensive care through summer and fall. Haven’t come across any seed that can take a bit of beating. Too early to judge this seed but some of the spots which were bare are hardly germinating, doesn’t look very promising as of yet"

— ASHWIN R. (3/5)

This stuff is fantastic! It

"This stuff is fantastic! It grew in a beautiful dark green with help from the starter fertilizer. I do highly recommend spending the money on the stuff that holds it in place. I got a surprise storm about 4 days after seeding and it did wash a lot away. But that’s more my fault than anything."

— Randy H. (5/5)

Was skeptical but it works.

"I’ve used multiple different brands over the past few years and they never worked. So I decided to use lawn synergy. I had multiple bald spots due to killing off crabgrass that grew through out my lawn. After preparing the area, I over seeded, covered with some top soil and used the starter fertilizer I also purchased at lawn synergy and within 10 days seeds started to emerge and with each passing day it’s starting to thicken. Very excited about the results and can’t wait until next year to fully over seed the entire lawn. I also plan on subscribing to the lawn program after years of the franchise companies costing a lot with little to no results."

— Xuong T. (5/5)

The grass seed and starter

"The grass seed and starter fertilizer is my first order so far. I'm happy with the results so far."

— Robert M. (5/5)

Overseed failure

"Last year my lawn was beautiful and green after I aerated dethatched put down topsoil and covered box store seed with a light layer of peat moss. This year was supposed to be even better so I bought a 25lb bag. I’d say only half of it has germinated after 2. 5 weeks. Not worth the money if it’s not going to fill out my lawn"

— Connor (2/5)

I pre-germinated the seeds for

"I pre-germinated the seeds for 7 days then I sewed them with compost topping and they come up right after the rain, 2 days later I had grass. It's slow to grow but it all come up. I'm keeping it watered.."

— Dennis H. (5/5)

The North Star I ordered

"The North Star I ordered is for my backyard renovation in September to eliminate the Bermuda in it similar to what I had in the front yard. Two consecutive fall over seedings in the front are starting to see good results and this year I started using Headway and the results have been dramatic."

— Thomas B. (5/5)

Overseeding compacted soil

"I put both of these down after aerating a very compacted area. This combined with composting and watering os lookinggreat. Plan to mow next week and maybe once more before winter gets here."

— Rob S. (5/5)

Q&A

Which seed blend would better for Eastern Nebraska? Envy Tall fescue or North Star Tall Feacue KY Bluegrass blend? My lawn is a newly sodded yard a little over a year old that I believe is mostly, if not all, Tall Fescue. I just aerated and would like to overseed and fill in bare spots caused by dogs.: North Star would be better for you. It contains 90% Envy Tall Fescue Blend and 10% 365SS Bluegrass Blend. It's a very special blend.
Is North Star okay to grow in transition zone - 7a? Why do you recommend envy premium tall fescue over the North Star for Washington DC area?: The summers in your area are little to warm to sustain bluegrass. Bluegrass performs better in cooler climates and will struggle with the summer heat.
Do you have to treat your lawn for weeds, before you use your grass seed and starter?: I would not recommend any post emergent **** control when planning to re-seed.
