Reservoir DG Wetting Agent, manufactured by Helena Chemicals, is a premium commercial granular soil surfactant that improves water infiltration and distribution in turf and landscaped areas, especially where localized dry spots or hydrophobic soils are an issue.

The "DG" in the name stands for dispersible granule technology, which allows the product to break down quickly upon contact with water delivering deep, uniform soil coverage without any mechanical disruption. One of the most powerful benefits of Reservoir DG is its ability to create uniform soil moisture, which is critical for healthy root development. Dry spots are no match for this formula - it helps pull water deep into hydrophobic soil areas where turf and plants can actually use it.

Reservoir DG Wetting Agent is a cost-effective and water-saving granular soil surfactant that helps water go deeper and stay longer in the root zone, reducing overall irrigation needs. With DG technology, dual-action wetting properties, and lasting performance, Reservoir DG is more than a wetting agent it’s a strategic solution to a complex turf and ornamental challenge.

Tools Needed

You will need a handheld spreader, push spreader, broadcast spreader, or seed spreader.

How to Use

  • Step 1: Determine how much Reservoir DG Wetting Agent to use by measuring the square footage of the treatment area. Find the square footage by measuring the treatment area's length and width in feet, then multiplying them together (length X width = square footage). For corrective treatment in turf, use 5 pounds of Reservoir DG Wetting Agent per 1,000 sq. ft. For preventative management in turf or after laying sod or applying grass seed, apply 3 pounds of product per 1,000 sq. ft. For trees and shrubs, use 3 pounds of product per 1,000 sq. ft. uniformly from drip line to trunk. For flower beds, shrub beds, and ornamental potting media mix 4 to 5 pounds of product per cubic yard. Refer to the product label for specific application rates and restrictions. 
  • Step 2: Adjust the spreader to the proper calibration then load the correct amount of granules. 
  • Step 3: Spread the granules evenly across the treatment area. For best results, it must be activated with irrigation or rainfall within 24 hours of treatment.

Where to Use

Reservoir DG Wetting Agent may be used on all species of established cool and warm-season grasses. It may also be used for ornamental gardens and landscapes.

When to Use

For best results, apply prior to a planned irrigation cycle and when the ground is dry.
