## Description

Primo Maxx Plant Growth Regulator

Review: This is for Bermuda Dominators - If you’re running Bermuda grass and you’re serious about your lawn, this is a game changer. This is the difference between a normal yard and that tight, golf course-style Bermuda everyone asks about. What it does is slow the vertical growth of Bermuda (the constant upward surge), and pushes that energy into lateral spread, density, and root strength. Bermuda already wants to spread — this product supercharges that. The result is a thicker, tighter canopy, fewer gaps, and a lawn that looks like it’s been professionally maintained. The biggest immediate benefit? Way less mowing. Instead of fighting fast top growth every few days, your grass stays more even while getting denser underneath. Over time, you’ll notice darker color, better striping, and improved drought and heat tolerance — huge for Bermuda in the summer. Yes, it’s expensive. But Bermuda responds so well to this that the value is obvious. A little goes a long way, and the results are not subtle. If you want that low, thick, elite Bermuda look, this is not optional — this is the secret weapon.
Review: seems to work - 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?

### ⭐⭐⭐⭐ Good but not as effective as I had hoped
*by D***C on April 1, 2026*

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.
