16-0-0 Double Dark blend will do just what the name implies: make your lawn double dark green. It's really that simple - green and more green.

  • One 45 lb bag covers 15,000 sq ft
  • Analysis is 16-0-0:: N-P-K, plus 6% iron
  • Contains Urea for a darker green color
  • Great for greening up the lawn but won’t flush it with too much growth

 

Product Description:
First off, let's just point out that Double Dark contains 6% iron. There are very few granular fertilizers available that have this much iron in them. We all know that iron is the key to that dark blue-green color, but...Double Dark also contains 16% nitrogen because one thing that so many people forget is that iron won't work if the lawn isn't actively growing.

Think about it: the lawn has to be growing in order to take in nutrients and what element stimulates growth? Answer: Nitrogen The secret to Double Dark is that the nitrogen and the iron are working together. Search around and you will hear people who say, "I was using Ironite but after a while, it just stopped working." That is because there is no nitrogen in that product to keep things growing.


The nitrogen we put in Double Dark Blend isn't over the top - it's just respectable at 16% and, one-quarter of that N is slow release. You will get some green from the N too, but it's not going to smack your lawn in the face and make it flush out a bunch of top growth. The nitrogen is really just there to stimulate intake. 

You can also apply Double Dark in between your regular fertilizer applications if you just feel like you want to sling some fert!

For Warm-season turf will benefit from sustained “spoon-feeding” monthly in summer with this product.

Cool-season turf will benefit from added color without a strong surge from too much N.

 

All-Natural Bio-Nite™ in Every Bag!
Bio-Nite is a bio-solid filler we add to every bag of Double Dark 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!

Foodville is excellent
Color: Turquoise Green
The Foodville frother is quiet, stylish, comfortable to hold, easy to clean and keeps a charge a long time. It has 3 speeds but is powerful even at low speed. I have it in turquoise and use it everyday to make oatmilk lattes. The battery failed after a couple months but when I reached out to Foodville, they shipped a replacement immediately and followed up to make sure I received it. I was so surprised with the excellent customer service that it was nearly disorienting - nothing at all like a maddening no-exit loop with a chatbot!!! I highly recommend this frother and the company behind it.

It’s possessed
Color: Coral Pink
My kitchen theme is pink and this was a perfect addition! Until it wasn’t! Fully charged it, and placed it in its holder ready for use the next morning. From my living room I heard a noise but of course blamed it on Rita (my cat). The next morning I go to make my coffee and the device is knocked over on the counter and of course.. poor Rita! The device worked fine, didn’t send my coffee into a tornado like some do, rinsed and placed in holder. Relaxing and enjoying my morning coffee and all of a sudden this noise happens again and I see the device is on and actively spinning in the holder!!! What the energy? I run to turn it off but it stopped before I can get there. Ok, let’s not panic. Next morning? Device is dead. So I recharge, and lay it on the counter buttons up. Later that night minding my own business, the device is now rattling across the counter!!! Ran over to it, pushed the buttons and it won’t stop! After about 45 seconds it stopped. I recharge again because it died, and the sad thing is still asystolic.. (no pulse), dead, gone. What the??? So I don’t know what to tell you! It looks pretty! Updated: The company reached out to me and I received a replacement within 2-3 weeks. The new one is not possessed or dancing across the counter. Good power, 3 speeds, 2 attachments (which I seem to use without the power - such as mixing spices). Thank you for standing behind your product in a volatile economic time.

Best frother!
Color: Ultra Violet, Color: Ultra Violet
Amazing customer service! I purchased this frother earlier this year and started using it for my morning coffee. It was amazing and froth up my creamer in no time. All three settings have their own amount of power. So I was very impressed with the speed. The froth texture is heavenly. After using the frother it is very easy to rinse the piece you used. I just rinse it and place it back in its stand. I think it’s very well worth its money. Unfortunately after 4 months the machine would not charge properly so I reached out to the company and within 24 hours, they replied and sent me a replacement. I didn’t pay much attention to the fact it had a 2 yr warranty! So grateful! Thank you so much for your help!

Powerful frother and g4ea
Color: Vivid Red
I love this frother, I bought one for myself and 2 others as gifts! It is super powerful, just the first speed is usually what I use for a cup of tea or coffee, the faster speeds work great for frother hot cocoa when I make a couple cups worth on the stove top. My frother attachment did crack at the top several months after purchase but the company immediately sent me a replacement piece which has been going strong for over a month now. Great handheld frother and company that stands by their products!

First one failed quickly, warranty replacement working great
Color: Turquoise Green
Absolutely loved this for the two months it worked but it completely stopped working after only 2 months. Update: I couldn’t decide on stars. The company honored the warranty and sent me a replacement. So far it is working great and I love it like my first one. Hopefully it will last. If it also fails quickly I’ll update again and take off stars. If it lasts I’ll increase stars because I really do love this. It works far better than any other one I’ve owned, it’s a nice light weight, comfortable to hold, has strong power, holds a charge well, has three speed options, and has a stand. I’ve tried multiple frothers. This one is by far the best one yet with best design and features.
