"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.

Cradle for a PC laptop charging block
Color: Black
Seems to be pretty durable. I haven't had it long. The adhesive is still holding up as I applied it to the wall for a vertical hang to keep the block off the floor in my studio. I don't recommend trying to apply this to a wall that would have some kind of texture as the adhesive probably wouldn't hold very well. It's made for flat surfaces only or a wood surface. Make sure you clean the dust off the area you plan to attach to. As everyone knows charging blocks for PCs are incredibly huge and heavy; so far so good.

Works great, super easy to install
Color: Black
Easy to mount, fits large charger great. Low profile appearance keeps it out of sight, functions perfect for my needs. The thick silicone material is nice and stretchy, thick so it should be durable.

Don’t but this…
Color: Black, Color: Black
The holder came quickly and isn’t that bad but mounts with a huge adhesive backing, which again isn’t;t bad, but it was sent in a plastic bad, like a zip lock bag. The adhesive backing has NO protecvtyive strip on it, so it is covered in lint and debris and was sticking to the bag it was sent in.
