GreenePOP Liquid Starter Fertilizer
Yard Mastery
N-Ext 16-21-2 GreenePOP is a liquid starter fertilizer designed as the ideal foundation product for seeding or sodding a lawn. It is equally effective on established lawns that require a phosphorus boost to address a deficiency. The formula also incorporates liquid aeration for added benefit.
GreenePOP is a complete fertilizer, meaning it delivers both macro and micronutrients alongside bio-stimulants — sea kelp and humic acid — to support overall lawn health. It is particularly effective at developing a strong, deep root mass. The combination of nitrogen, phosphorus, and potassium, enhanced by humic acid and sea kelp, nourishes newly rooting turf while conditioning the surrounding soil to promote faster germination.
Key active ingredients include potassium hydroxide, which acts as a liquid aerator by breaking soil bonds and creating space for root growth; humic acid, which serves as a carbon source and chelating agent; and sea kelp, which stimulates microbial activity. GreenePOP is also well-suited for phosphorus-deficient soils and can be used as part of a balanced fertility program across all turf types.
Application: Apply 15 oz per 1,000 sq ft. For sod, apply directly to bare ground; for seeding, apply directly over the seed. This product can also be applied pre-plant or incorporated into a topdressing medium. Water in after application and repeat after 15 days.
Watering Instructions: Water the product into the soil within 24 hours using ½" of rainfall or irrigation. Do not apply to saturated lawns. Rinse any excess product from sidewalks and driveways to prevent staining.
Rate: 15 oz per 1,000 sq ft
