Cool Season Winterizer Pack: Kentucky Bluegrass, Perennial Ryegrass, and Turf Type Tall Fescue - use this pack to put your lawn to bed properly so it can wake up and blast off next spring.

SAVE 25% vs Buying Separately!!

This pack Includes:

  • (1) 18 lb bag of 24-0-6 Flagship lawn fertilizer
  • (1) quart of Humic12
  • (1) quart of Air8
  • (1) hose end sprayer top
  • (1) empty quart bottle
  • Custom Flagship Magnet

    Product Description:

    The definition of “winterizer” is important. It literally translates to “the last application of the year,” and for cool season lawns, there is nothing better than our best-selling crafted lawn fertilizer, 24-0-6 Flagship!

    The idea behind a winterizer is you apply a blast of heavy nitrogen late in the season just before the ground freezes. The key is to get down the winterizer after the lawn has stopped growing but before the ground is frozen. This app is for next season.

    The Air8 in this pack is for penetrating into the soil, opening up space for air and water to permeate. We then add in additional humic acid (Humic12) to fill some of that space with carbon which is great for the soil.

    • 24-0-6 Flagship: This granular fert is explicitly formulated for DIYers. It is your go-to fertilizer for all grass types, designed to get the lawn thicker and greener.
    • 0-0-1 Humic12: This liquid bio-stimulant is great for root growth, chlorophyll content, nutrient uptake, soil structure, water retention, and plant quality.
    • 0-0-5 AIR-8: This liquid aeration with humic and fulvic is designed to create space in the soil, increase water penetration, and encourage deeper rooting to drive more oxygen into the topsoil profile.

    The three of these products work together to prep your turf for take-off in the spring! By bundling the products together, we are able to pass along significant savings over purchasing separately.

    Application Information:

    First off: if you are still mowing your lawn at least every 10-12 days or so, then you can utilize this pack. If you are NOT mowing anymore and your lawn has gone dormant, then it’s too late for you to use this pack this season.

    When your pack arrives, break out the Air8 and Humic12 and apply 6oz/1,000 sq ft of each using the hose end sprayer that came in your pack, (YES you can mix them together). Water it in.

    Here is a video Allyn put together showing you the rates recommended this time of year:

    Now things will start to slow down here in the next several weeks depending on how far north you live, but just keep mowing as needed.

    Then when you get to that point where you feel like the lawn has completely stopped growing and you will not have to mow anymore, that is when you apply the 24-0-6 Flagship lawn fertilizer. There will be a time when you look at the lawn and decide to give it one final trim, just to clean off the tips and get up any last falling leaves. Right before that big predicted snowstorm… That’s when you throw down! (or do your best to get close and hope for the best!)

    The idea is that this final Flagship application is not for the lawn to use now.

    Instead, it will be utilized next spring as the snow melts and waters it in for you. This is the best way to get an early jump in the spring coming out of winter, greener than everyone else, fast!

    Great value filters – do the job well
    Pattern Name: 12x12x1, Style: Merv 8
    These filters are a great value for the price, especially getting a 6-pack. They fit perfectly (just keep in mind the actual size listed), and installation is quick and easy. I’ve been using them regularly and they do a solid job catching dust and keeping the air clean without restricting airflow. Good balance between filtration and performance. Nice to have multiple on hand so I can swap them out regularly without thinking about it. I’ll definitely keep buying these.

    These Amazon Basics air filters fit perfectly and were easy to install. They help keep the air cleaner and the HVAC system running smoothly. Good quality for the price, and the 6-pack is convenient to have on hand for future filter changes. Definitely a great value purchase.

    Cool, Fluffy, and Excellent Value
    Color: White, Size: Queen (Pack of 2)
    I recently got the Utopia Bedding Queen Size Bed Pillows (set of 2), and they’ve quickly become my favorite pillows for a good night’s sleep. Right out of the package, they fluffed up nicely and feel soft yet supportive. The down alternative filling gives a plush, comfortable feel without being too firm or too flat, and the gusseted design adds extra support for back, stomach, or side sleeping. I’ve tried them in all positions, and they hold up well without collapsing overnight. Another big plus is that they stay cool while I sleep. Even during warmer nights, I don’t feel overheated, which makes a huge difference in comfort. The pillow covers are smooth and feel like hotel-quality fabric, giving the bed a clean, luxurious look. The only minor thing is that they may take a little time to reach full fluffiness after the first wash, but that’s normal for down alternative pillows. Overall, these are soft, supportive, and high-quality pillows at a great price. They’ve improved my sleep noticeably, and I’d definitely recommend them for anyone looking for a comfortable, versatile pillow set

    Well priced luxury feel.
    Color: White, Size: Queen (Pack of 2)
    This set of 2 pillows is very luxurious and comfortable to sleep on with good height but not so much as to elevate or lower the head to an uncomfortable degree. I just received them so they need time to air and expand fully but right out of the compacted box they are full and very comfortable. The fabric is very soft and there is no odor. These pillows are definitely a good price for such a luxury item. I think I will enjoy them for some time to come.

    Soft...but fluffy and tall
    Color: White, Size: Standard (Pack of 2)
    I've only had these pillows for about a week. They are a great quality pillow. The cover is soft and seems well made. My only complaint is that they are VERY full pillows. If you're tall with broader shoulders, you'll probably love them. If you're shorter with a smaller frame you will probably feel like your head is too high and your neck at a weird angle (my problem). There seemed to be mixed reviews about softness....I would consider these a nice medium pillow. Soft filling but firm enough that your head doesn't sink to the bed. Definitely NOT a down-like pillow, so if that's what you're looking for, this is not for you.
