Give a larger cool-season lawn one focused fall feeding with GreenView Fairway Formula Fall Fertilizer 30-0-12, which lists 59 percent slow-release nitrogen for feeding up to 12 weeks. Its 30-0-12 balance, including 12 percent potash, is made for autumn root building and winter hardiness support, while the 45 lb bag covers 15,000 sq ft.
Description
GreenView Fairway Formula Fall Fertilizer 30-0-12 is made for one clear job: a focused fall feeding for a larger cool-season lawn. Many lawn owners feed well in spring and then run out of time, so autumn arrives with a lawn that needs steady support before winter.
This formula answers that problem with 59 percent slow-release nitrogen and feeding for up to 12 weeks, so one autumn application can carry the lawn through an important part of the season. It is for cool-season lawn owners, especially in the northern and transition zones, who want a simple fall plan rather than a product that tries to cover every season at once.
That combination of timing, slow release and potash is what separates a specialist autumn feed from a generic lawn feed, and it is why this page focuses on the fall job first.
Key Features
A fall specialist, not an all-season compromise
GreenView Fairway Formula Fall Fertilizer 30-0-12 is described in the roundup as the fall specialist. That focus matters, because fall is when cool-season grass builds roots and stores energy. A product built for that window can match the season, rather than asking one bag to do spring, summer and autumn work in the same way.
59 percent slow-release nitrogen
The formula lists 59 percent slow-release nitrogen. Slow release means nitrogen is metered out over time, rather than being released all at once. For a fall lawn, that steady supply fits the longer feeding window and helps avoid a short surge followed by a fade.
A 30-0-12 balance with 12 percent potash
The analysis is 30-0-12, which means 30 percent nitrogen, no phosphorus and 12 percent potash. The 12 percent potash is a central reason this product exists, because potassium supports winter hardiness in the maker position described in the roundup. The zero phosphorus figure also matters for lawn owners who do not need phosphorus added in autumn.
Feeding for up to 12 weeks
GreenView Fairway Formula Fall Fertilizer 30-0-12 feeds for up to 12 weeks. That window gives a fall application time to support root building and stored energy, without asking the lawn owner to return every few weeks for another full application.
Large lawn coverage from one bag
The 45 lb bag covers 15,000 sq ft. That scale makes it a practical choice for a larger lawn, where a small bag would need several purchases and several spreader fills to cover the same ground. Check the live listing for the bag size on offer before you buy.
Product Description
GreenView Fairway Formula Fall Fertilizer 30-0-12 is a lawn fertilizer built around autumn timing, slow-release nitrogen and a high potash share. Its place in the roundup is clear: it is the pick for a fall application on a larger lawn, with an editorial rating of 8.9. That rating is an editorial score only, and it is not a claim of hands-on testing.
The roundup checked the official GreenView label, in manufacturer PDF form, for the 30-0-12 analysis, the 59 percent slow-release nitrogen figure and coverage, and it checked a Do it Best listing for the 45 lb bag. Those are the verified figures used on this page. Where the roundup or maker does not publish a detail, this page says so plainly, rather than filling the gap with a guess.
For a cool-season lawn, the appeal is timing. Autumn growth is often less visible than spring growth, because much of the work happens below the surface. Roots and stored energy matter for the months that follow, and a fall formula is designed to support that work. This product keeps that job in focus, instead of spreading its purpose across the whole year.
Benefits of Using This Product
GreenView Fairway Formula Fall Fertilizer 30-0-12 offers a set of clear, practical benefits for the right lawn at the right time:
- A focused fall feeding, timed for cool-season root building and energy storage.
- Steady feeding for up to 12 weeks from 59 percent slow-release nitrogen.
- Potash support for winter hardiness, with 12 percent potash in the 30-0-12 analysis.
- No phosphorus in the analysis, for lawns where phosphorus is not needed.
- Large lawn coverage, with a 45 lb bag covering 15,000 sq ft.
- A simple autumn plan, with one product for one seasonal job.
The benefit is not that this product does everything. The benefit is that it does one seasonal job clearly, and it does it at a scale that suits a larger lawn.

How to Use
Use GreenView Fairway Formula Fall Fertilizer 30-0-12 in autumn, as a fall feeding for a cool-season lawn. That timing is the point of the product, so plan the application for the fall window rather than treating it as a general spring feed.
Before you buy, check the live listing for the bag size on offer and for any label guidance on spreader settings and application rate, because those details are not published in the roundup section and are marked as Check listing on this page. Follow the product label for the application you make, and keep the lawn size in mind: a 45 lb bag is listed to cover 15,000 sq ft, so measure your lawn before you order if you are unsure how many bags you need.
Do not use this fall product as your only spring product. The roundup gives that limitation plainly, and it is worth repeating here, because using a seasonal formula outside its season misses the point of its design.
Why Choose This Product
Choose GreenView Fairway Formula Fall Fertilizer 30-0-12 if your lawn is a larger cool-season lawn and your main need is a clear autumn feeding. It suits northern and transition zone owners who want one focused application, steady feeding for up to 12 weeks, and potash support for winter hardiness, without adding phosphorus.
It is less suitable if you need a spring rescue product, a small lawn feed, or a product for beds and containers. It is a lawn product for a fall job, and its strength comes from that focus. If your lawn is small, check whether a smaller bag or a different product fits better, because the 45 lb bag is built for scale.
The editorial rating of 8.9 in the roundup reflects its fit for that fall, large lawn job. It is an editorial score only, based on verified specifications and the roundup method, not a claim of hands-on testing. Read it as a guide to fit, then check the live listing for current price, bag size and label details before you buy.
