Review: Worth it - 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!
Review: Great product, easy to apply evenly - 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.
