Advanced 16-4-8 Lawn Fertilizer - Liquid Lawn Food Spring & Summer Concentrated Spray - Any Grass Type- Fish and Seaweed Kelp- Balanced NPK - Simple Lawn Solutions (1 Quart)

I discovered this company first when reading about their liquid aeration product (worked well), then tried the humic acid (also worked well), and now have used the 16-4-8. Like many people who posted negative reviews on the 16-4-8, I had some initial difficulty with the included hose-end sprayer. It did siphon product, but the hose end leaked fresh water badly, soaking me in the process. When refilling the quart sprayer from a gallon container I also purchased, I noticed there was no o-ring in the hose sprayer. I had a new one on hand, installed it, and the sprayer then worked flawlessly without leaking a drop. I have a big lawn and probably applied 25% more product than recommended by choice, but the sprayer worked well once the o-ring was in place and all three refills sprayed consistently until empty. One day after mowing, I applied 16-4-8 in the late afternoon; overnight there was a light but steady rain. 24 hours after application, the grass seemed a little greener, but what was more noticeable was how much springier and healthy the grass plants looked and felt underfoot. 48 hours after application and an additional watering, the lawn looked even better. Not necessarily that dark, golf-course green you get from super high-nitrogen Scotts granules, but fuller looking and more consistent throughout. I live in a wooded rural area and am not going for the idealized, real-estate brochure lawn, but this product makes my "ordinary" grass look the best it has in years. The price is reasonable too if you buy the gallon size. You can also use the sprayer for this company's other products--the humic acid doesn't come with a sprayer, but the 16-4-8 top screws right onto the humic acid quart. I live in northern Michigan and have mostly tall fescue. Will be eager to see if this product helps me get through dry July without too much yellowing--will update here if needed. But as of right now, this will be the fertilizer I use from now on. 30-day update: after almost three weeks of hot dry weather, which came early this year, the 16-4-8 has continued to impress me. I have tried a new watering approach during periods of no rain this year, only watering once every three or four days (a bit more extensively, though) instead of almost every day. Between this new regimen and this product, my grass continues to look better than it ever has. I would've thought using a liquid product would give quicker results but fade more quickly than dry granules, but in fact the opposite has been the case. When we finally got some soaking rain a few days ago, the grass really perked up again, moreso than in previous years of similar dry spells. When nights start getting cooler in a month or so, planning to apply humic acid again, then another dose of 16-4-8 maybe a week later. Also continue to be impressed with the loosening effects of the liquid aerator product, which have held up nicely over about 8 weeks. Great company.

Great product. This is the first liquid fertilizer Ive used. Ive always used granules priorly. The results with the liquid is way better. Ive applied once monthly 3xs this year and the Bermuda has never looked better. People say its expensive but Ive had to water much less which is much more expensive. My neighbor uses a national lawn treatment service and is jealous of my yard.

We have a mature St. Augustine lawn, which means it is very dense and it grows on a layer of thatch. Granular fertilizers just can't get easily into the soil. Since we started using Advanced 6-4-8 liquid fertilizer the lawn has never looked better. My only complaint is that the garden hose applicator bottle could have a better on-off valve. It's a little stiff. Also, you have to be very quick with the application since the sprayer goes through the quart of fertilizer in no time flat. Apply quickly and then water it in a little. We started buying it in the 1 gallon bottle and using an Ortho sprayer set on 3 oz., as recommended and you can do the application more slowly.

Light on fertilizer ingredients but probably is exactly as designed. Perhaps this is good for a freshly laid hydroseeded lawn where you don’t want to burn it out. Good product. Pay attention to details on it. Not the best for established lawn

Didn’t see any improvement in my plants

Fantastic product, I use it every three weeks with other products and spray it on my lawn with a hose end sprayer. I have the most beautiful lawn and plants.

I have used it for a few months and not to impress yet, but could be the high temps.

Great lawn fertilizer! Easy to apply and works fast—my grass turned greener and healthier within days. Love that it works on any grass type and the results are very noticeable. Definitely worth it!
