Primo Maxx Plant Growth Regulator

so far it seems to be working. applied twice as the first time the mix was weak and haven't mowed since. the grass kind of yellowed for a few days but first rain bought the green back. i had bought a tow behind sprayer and learning how to use that to spray this took a little bit, but after that had all the bus worked out everything spayed great. if this can keep me from having to mow the yard that seems to get bigger every summer more then twice all summer its well worth it. going to spray the rest of this container in another week or so and see from there but right now its working. maybe enough will keep it green and short all summer?

Must have for thick green lawns

I had fairly high expectations for this product, and while it definitely works, it didn’t quite deliver the level of results I was hoping for. Application was straightforward, and I did notice some reduction in growth rate, which meant slightly less mowing. That part held true—this product is designed to slow vertical growth and redirect energy into thicker turf, and it does seem to help in that regard. That said, the overall effect felt a bit more subtle than expected. I was hoping for a more noticeable difference in growth suppression and lawn appearance, but the results were somewhat modest on my lawn. It may work better with very consistent applications or under ideal conditions, but it wasn’t a dramatic transformation for me.

Actually works! It's spring time and I have a robot mower. Robot mowers make your lawn look amazing, all day every day. One downside is it makes it look like you always have to trim! I applied this as directed along borders in my front yard and it was easy to compare the side with the regulator and side without, it definitely slows down the growth. Happy I made the purchase - it's a small bottle but will likely last me the season.

Seems to work. Out of curiosity I only sprayed about 3/4 of my hard to reach areas so I would have something to compare and you can definitely tell what was sprayed and what wasn't.

Anything that keeps you from being behind a lawn mower in south Louisiana in the middle of summer is worthwhile. After one week, it still looked fresh cut. can't wait for the second application. I may apply that one at 3 weeks instead of 4 just to experiment with it.

Good product

Too late in the season to use right now and still waiting for grass to fill in, in some spots from aerating and sand leveling. Excited to use next season though, hear this stuff is great for lateral growth and easy to use.
