How did you first trial ThatchZyme? What were your target areas, duration, and objectives?

ThatchZyme was applied at 35 oz/acre to 2 acres of primarily bentgrass tees mowed at 0.350". The first application was on April 15, 2026, with applications continuing every 4 weeks through October 2026, for a total of 6 applications.

All applications included wetting agents, fertilizer, biostimulants, and growth regulator. Some also included fungicides and insecticides. All applications were watered in immediately with about 0.1" of irrigation and additional overnight irrigation or rainfall.

How did you measure or notice changes? Were there any other turfgrass responses observed?

Each of the last several years, our tees became puffy and scalped while mowing at our normal heights in July and August. To combat this, we raised mowing heights, switched to solid rollers, and even rolled the surfaces.

This year, after 3–4 applications of ThatchZyme, we noticed less puffiness, no scalping, and were able to keep our normal mowing heights and grooved rollers on the mowers all summer. We also did not have to roll to combat thatch buildup.

Overall, how did the product perform compared to your goals and expectations?

What a difference we have seen in the last couple of months! I do not have organic matter testing to prove it, but our tees did not scalp in July and August as in years past. The puffiness is noticeably less as well, so I am confident the product is working in our favor.

I plan to continue using it on tees and want to add 5 gallons to start treating approaches and possibly greens.

Any other insights or recommendations for fellow turfgrass managers considering ThatchZyme?

As with any other new product, try it out on a known problem area to evaluate if it will work to help your situation.

I also believe ThatchZyme, or any other product you are trying to move into the rootzone, needs a good penetrating wetting agent to get it there.
