AlphaLawn Turf Winterizer

Turf Winterizer is an organic fertilizer best utilized in the fall, as it conditions and loosens compacted clay soils, deepens and strengthens root systems, enhances the turf, roots, and soil foundation and encourages early growth and health for the following spring.

Essentially, this fertilizer develops greater plant-drought tolerance for the spring and summer months ahead by ensuring stored nutrient reserves in the root zone of your lawn are plant- ready when the soil thaws and spring arrives. With earlier spring root and leaf growth, you’ll begin to see improvements in turf density and thus, additional foliage cover to minimize spring weed seed germination.

Manufactured in Colorado, this product is specifically designed with organic amino to counteract alkalinity of calcareous soils and create a better soil environment for all varieties of turf grasses. The homogenous nutrient balance lacks manures, sludge, and waste materials, only using the best ingredients. In addition, this turf food distributes plant-ready nutrients through a natural time release process, making them available to the turf for much longer.

How to Apply

For enhanced benefits and results, we recommend aeration before applying AlphaLawn Turf Winterizer. In September or October, you can broadcast at the rate of 8 to 10 lbs. per 1,000 sq. ft., as long as you thoroughly water the area after application.

The fall application of AlphaLawn Turf Winterizer will deepen and strengthen root development and provide an earlier green up for the following Spring.

This earlier spring growth will produce a denser foliage that will inhibit weed seed germination.
