  • One gallon covers up to 8,000 sq ft

Product Description:
GreenePOP is engineered to deliver all that grass seed or sod needs to get growing quickly and start life on the right foot. The combination of nitrogen, phosphorus, and potassium with humic and sea kelp delivered with GreenePOP will feed the newly rooting turf and prepare the soil around the seed for quicker germination.
These active ingredients here are the key to helping your seed or sod get established:

  • Potassium hydroxide (liquid aeration) is included in this starter fertilizer. This dives into the soil and breaks bonds, creating space.
  • Humic acid is also included as a carbon source and chelator as well as sea kelp microbial stimulant.

GreenePOP can also be used for phosphorus-deficient soils or used in a balanced fertility program on all turf types. This product can be applied directly on top of seeds at the time of planting, applied pre-plant, or incorporated with a topdressing medium.
