Soil Moisture Management

Hydretain® Retail

Root Zone Moisture Management

Reduce watering, delay wilt and increase nutrient uptake with Hydretain. Hydretain uses hygroscopic humectant technology to convert soil humidity into plant usable water droplets, so you can water less and still maintain heathy, great looking plants. By making use of moisture that would otherwise be lost to evaporation, Hydretain improves water and nutrient uptake to help plants thrive, even under heat and drought stress. One gallon jug can be used as a refill for the quart hose end sprayer.

Effective for lawns, shrubs, trees, flowers, fruits and vegetable gardens, and container plants.

Where to use

  • icon Long Description

    Hydretain is a unique technology designed to help plants thrive with less watering. It contains  hygroscopic humectant compounds that capture moisture in the soil, which would otherwise be lost to evaporation. Captured vapor molecules accumulate to form usable water droplets that are passed to the roots of plants, minimizing drought stress, extending the time between required watering and reducing overall water demands by up to 50% or more. In addition to reducing irrigation, delaying wilt and minimizing dry spots, Hydretain is also helps improve the uptake and performance of many other products, including plant nutrients. Hydretain Retail Products combine the Hydretain technology with an advanced, naturally derived soil surfactant for improved penetration and distribution in hard-to-wet soils.

    Each application lasts for up to 3 months.

  • icon Application Instructions

    Hydretain may be applied through a hose-end sprayer, fertigation or soil drench. It may be applied alone or tank mixed with other products.✝

    Dilution: Hydretain is a concentrated formula designed for large scale applications. Dilute with water before applying. Minimum dilution rate 15:1 (water to Hydretain). Hydretain may be tank mixed or applied through injectors and fertigation systems.

    Apply 9 oz. of Hydretain per 1,000 sq. ft. (3 gallons per acre) by spray or drench. Water in with at least 1/10 inch of water within the first couple of hours to insure Hydretain is washed off foliage and into the soil. Within 24 hours, follow with enough additional water to carry Hydretain down to and throughout the root zone. (The amount of additional water required to carry Hydretain throughout the root zone is dependent on the depth of the root zone of the treated area.) Reapply once every 3 months or maintain monthly at 1/3 rate after initial full rate application.

    Overseeding, Sodding, Sprigging:
    Apply 9 oz. per 1,000 sq. ft. by spray or drench after seeding, sodding or sprigging. Water in with only enough water to rinse Hydretain off foliage and into the soil at seed level or the root area of new sod or sprig. An application of Hydretain made prior to overseeding, sodding or sprigging and watered into the root zone will manage soil moisture for existing turf during new turf establishment.

    Trees, Shrubs & Individual Plants:
    Dilute Hydretain at a rate of 2 oz. per gallon of water and apply by drench thoroughly saturating the root zone. For maximum effectiveness on trees apply 4 to 8 ounces of concentrate for each inch of trunk diameter. Dilution rate is variable from 50:1 to 300:1.

    Potted or Containerized Plants:
    Dilute Hydretain at a rate of 2 oz. per gallon of water and apply by drench, thoroughly saturating the planting media. Media should be dry enough to hold as much diluted Hydretain as possible. Hydretain may be applied through existing injectors at rates between 50:1 and 100:1. Higher dilution rates may require multiple applications to achieve desired results.

    Large Planters & Gardens:
    Dilute Hydretain at a rate of 2 oz. per gallon of water or through injectors at a rate of 50:1 to 100:1 and apply at a rate of 2 ounces of concentrate per 60 sq. ft of area. One gallon treats 4,000 square feet. For Best Results: Water thoroughly when re-watering Hydretain treated plants.

    For Best Results: Apply to damp soil. Additional Hydretain may be required to correct difficult and extreme dry spot areas. Hydretain may be applied at up to 5 times the general application rate as a single treatment or in multiple applications. Hydretain is biodegradable. For maximum effectiveness reapply every three months or when required watering becomes more frequent. Reapply if a reduction in watering is not apparent within the first two weeks.

    Wetting Agents & Penetrants: Hydretain contains an excellent soil surfactant designed specifically to allow water and applied Hydretain to penetrate through thatch layers and hydrophobic soils down to and throughout the root zone.

    ✝ Compatibility: perform a standard jar test to check compatibility with other products before mixing.
