Help your lawn make better use of every drop of water with Yard Mastery Moisture Max™ Granular. This granular soil moisture manager is designed to help retain soil moisture, improve water penetration, and support deeper, healthier turf roots.
Moisture Max combines humectants, a penetrating surfactant, and sea kelp to help manage moisture in the soil profile. Humectants help hold water in the soil, while the penetrating surfactant helps break the surface tension of hydrophobic soil so water can reach the turf root zone more effectively. Sea kelp helps encourage thicker, deeper roots so your lawn can use more water before it evaporates.
Moisture Max Granular is useful for lawns that dry out quickly, develop recurring hot spots, or struggle to absorb irrigation evenly. It is an easy DIY solution for treating an entire lawn or targeting stubborn dry spots. It spreads through a common broadcast spreader, does not have an unpleasant odor, and can be applied to all major cool-season and warm-season grass types. Apply it as part of a complete lawn care program to support moisture management during hot and dry periods.
What is Granular Moisture Max used for?
Granular Moisture Max is a lawn moisture management product designed to help retain water in the soil and improve moisture movement into the turf root zone. It contains humectants, a penetrating surfactant, and sea kelp to help break surface tension and encourage deeper, thicker roots. It can be applied across an entire lawn or used to target persistent dry spots.
Does Granular Moisture Max need to be watered in?
Yes. Water Granular Moisture Max into the soil within 48 hours of application using approximately ½ inch of rainfall or irrigation. Do not apply if heavy rain is expected, and avoid allowing granules to remain on sidewalks, driveways, or other hard surfaces.
