Hydretain does is draws humidity out of the air and bring that water down into your grass root system! 

Now what that means is that because you’re getting water sucked into the roots from the air, you can reduce the watering requirements of your lawn by up to 50% or more! Hydretain is an excellent lawn moisture manager.

As I've learned after using it, Hydretain is one of those secret ingredients that golf courses, towns, and municipalities use to save on their water bills!

This product cannot go on dry soil, it needs initial soil moisture so apply after a rain or after you've watered.

After applying water in within 24 hours with a full 1/2” of water. This is extremely important, the product needs to get into the soil to work effectively.   

Hydretain will stay in the soil for about 90 days.

So if you live somewhere like Montana you can apply once in June and be set for the summer but if you live somewhere like TX or FL where we have longer seasons, you'd do two applications ~60 days apart.

Hydretain can be used on all grass types, such as the following:

Cool Season Lawns - Kentucky Bluegrass, Turf Type Tall Fescue (all fescues), Ryegrass
Warm Season Lawns - Bermuda, St Augustine, Zoysia, Centipede, Bahia
