"Starter Fertilizer Fixes Everything!" This 12-12-12 is your go-to for seed/sod or general feeding, formulated specifically for DIYers.

 

  • One 45 lb bag covers 15,000 sq ft 
  • Analysis 12-12-12:: N-P-K
  • Contains 3% Iron + Bio-Nite™
  • Great for seeding/sod installation


Product Description:
The Yard Mastery Starter Fertilizer contains 12% nitrogen, utilizing premium nitrogen source ammonium sulfate which brings a really nice steely-blue-green color to turf and interacts well with the other elements in the overall blend.

 

This blend also contains 12% phosphorus, which is plenty to push roots in an existing lawn or stimulate rooting in your seed, sod, plug, or spring project. Rounding out the macros is 12% potassium. Here we have opted for the premium formulation, sulfate of potash, known to have a lower salt index. As with all Yard Mastery blends, we have also included a nice amount of iron at 3% and a smattering of other micronutrients including boron, copper, manganese, molybdenum, and zinc.

 

All-Natural Bio-Nite™ in Every Bag!
Bio-Nite is a bio-solid filler we add to every bag of Starter Fertilizer. Bio-Nite is the same thing as Milorganite, but instead of being sourced in Milwaukee, it comes from South Florida. We can tell you that it “smells like a whole lot of success!” The good news for you is that the smell tells you that the included Bio-Nite is feeding microbes in the soil every time you apply and they love it!


Application Information:
So, for sure, you can apply Starter Fertilizer when you seed or sod, but it’s also great for anyone just looking for “all the things”. If you have a soil test that shows that you are low on the 3 big macros, (Nitrogen, Phosphorus, and Potassium), this is an excellent choice. Starter Fertilizer can be used on the following grasses:


Cool Season Lawns - Kentucky Bluegrass, Turf Type Tall Fescue (all fescues), Ryegrass.
Warm Season Lawns - Bermuda, St Augustine, Zoysia, Centipede, Bahia.

A Good Night’s 💤
Size: Standard (Mid Loft), Number of Items: 1
I’ve bought many pillows over the years and this pillow is by far the best for me. I am a back and side sleeper. Finally wake up without a headache or neck discomfort. I bought the medium standard. Just the right consistency. Not to soft not to firm. Stay cool pillow.

Confortable

Excellent support. Always fluffy. It does have a smell but as recommended I let it air out for a day. I also washed the cover and had no issue.

Perfect latex pillow
Size: Queen Size
I’ve been using the pillow for about a week, and I’m really happy with it so far. It’s soft and bouncy but still gives enough support for my neck, which is hard to find in a pillow. When I first received it, there was a slight odor from the new materials, but it went away after about two days, so it wasn’t a big deal at all. What I noticed right away is how it kind of molds to your head and neck without feeling too firm. It’s definitely more supportive than regular foam or down pillows, but it’s not stiff at all. I also like that it stays cool throughout the night—I never wake up feeling overheated. Overall, it’s a solid choice if you’re looking for a pillow that’s soft but not too soft, with enough support to keep your neck comfortable. Definitely worth trying if you’re picky about pillows like I am.

Our favorite pillows & we're picky!
Size: Queen Size
My whole family love these pillows, & we are picky pillow people! They are comfortable through the whole night & I get the best nights sleep. We even put them in our AirBnB house & guests ask where they can buy one. I highly recommend. They are soft on your head but still supportive.
