My lawn looks fantastic since
"My lawn looks fantastic since starting this program. This is so much better than having the typical spray company treat the yard. I have used all of these "spray" companies local here and the result was always the same with the same results. I now have have bright green almost blue grass(St Augustine ProVista) thanks to your program of DYI."
Excellent Help
"I found Lawn Synergy about 1. 5 -2 yrs ago for my new Bermuda lawn. Yes, their products are awesome ( I use fertilizer (Almighty ) , sledgehammer and Celsius ). All are great, BUT the best part is their help. I email questions and pictures all the time. Very quick to reply and spit on help! Love them and will us them as long as I have this house. Btw, my yard looks kick ass! Steve"
Excellent products
"We bought our house in Fall of 2025 and the lawn was ok but had a fair amount of weeds and bare patches. Since starting the program there has been a significant improvement in how the lawn looks. The lawn is now green and lush noticeably greener than all of our neighbors who use the major treatment companies. I've used other brands seasonal subscriptions but they definitely did not work as well as this does."

Q&A
- How soon after laying bermuda sod should i fertilize with 20-0-10?
- You should wait at least 6 weeks to apply if you have already applied starter fertilizer when the sod was installed. If starter has not been applied yet, suggest applying starter and then 6 weeks after, apply the next fertilizer application.
- This is what you recommend for fall ? Is this like a Winterguard ? I have Kentucky blue grass. What is recommended for bindweed . It’s a vine weed. Why is yours better than others ? I’m trying to make my grass thicker and greener. I just had aeration done .. Put cheaper stuff on the back. Until my neighbor over-seeded his with nitrogen ! Trying to beat out a landscaper ! Help! 😂 Thank you

- what do you recomend for the fall application of pre emergent and fertilize for st augustine grass in zone 9?
- I would recommend 13-0-10 Guardian as a fertilizer and pre-emergent for St Augustine Turf in the fall.
- Can I put this fertilizer down in this hot heat in st. Louis?
- I live in Florida and it’s working wonderfully on my centipede grass.
- Can I put this fertilizer down in this hot heat in st. Louis?
- Put it down early evening then water it in thoroughly. If your really concerned do split treatments, put half down and water in and put the last half down a day or two later. Its a granular which takes time to start working.
