N-Ext 16-21-2 GreenePOP™ is a liquid starter fertilizer. If you are seeding or sodding your lawn, this is your foundation product. It's also great for existing lawns if you need a good dose of phosphorus to correct a deficiency. Also includes liquid aeration in the mix.

  • One gallon covers up to 8,500 sq ft
  • Analysis is 16-21-2::N-P-K

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.

My lab loved it too much, too fast…
Color: blue, Color: blue
It arrived an hour ago and my lab has it in pieces within minutes. It kept him busy for a bit though! I’ll give it to him again but I’ll have to sit with him, for sure. No squeak? I guess he just didn’t get to that part of the toy. It felt sturdy but ultimately didn’t pass the test.

Colorful, Sturdy & Great Value
Color: Large Set of 4
Purchased for our two puppies when they were 2 months old and weighed about 14 pounds so theses balls were a little big for them to hold in their mouths but that didn't stop them from trying. While they did like these balls they much preferred softer soccer balls, the later of which did not hold up well at all. I had hoped they would play with these balls more when they were older but that hasn't happened 5 months later. I guess it's no fun if you can't tear the toy apart. Colors are very bright and they do enjoy chasing after them as long as I am the one rolling them across the room for them. Maybe when they progress to batting things with their paws they will start to do this for themselves.
