First year with Sunday
It's been an amazing experience thus far. Yard is looking at its best!

Looking like a golf course in my yard!
Sunday has my lawn looking green, healthy and ready for enjoyment for the family, kids, dog and neighbors. The applications are easy to do, and I've been happy with the results. It gets VERY dry for weeks and weeks during the summer in Seattle, and their soil analysis did a good job of giving me the right kind of ingredients to make sure that our soil and grass retain water and stay as healthy as possible!

I tried Sunday this past year and I'm so impressed. I followed the Sunday schedule and I've never had a more plush, thick green lawn through the summer, fall and now winter. I'm one of those neighbors that wants the best looking yard on the block (even with two dogs) so have tried everything. I'm now sold on Sunday!

Peace on Earth!
Using Sunday's amazing products, our yard has been transformed into THE neighborhood icon of beauty. Over the last year, two marriages have been saved and three healthy babies were born on our block…that never would have happened if I had still been using my dad's old fertilizer spreader. Just last night, while applying my latest pouches, I could feel my blood pressure returning to healthy levels and am certain I heard angels receiving their wings. Thanks Sunday for restoring order in my community!
