Pendelton Turf Supply 18-3-6 Liquid Fertilizer

This liquid fertilizer from Pendelton Turf supply is a good all-around nitrogen-rich fertilizer that comes in close to the 16-4-8 ratio I prefer. I’m including it because 50% of it’s Nitrogen is slow-release, which makes it different than a lot of the liquid fertilizers on the market.

If you want to skip granular applications in your lawn care program, this can be a good alternative, giving you the benefit of both short-term and long-term feeding from a single application.

The nitrogen in this product is from controlled-release methylene ureas, offering excellent green-up without the extra work mowing your lawn following application. It’s a great option for those seeking a low-maintenance yard that looks great.

One 2.5 gallon jug will fertilize ~14,500 square feet at manufacturer’s suggested application rate

Why Macro-Nutrient Ratios Matter

Explaining N-P-K Macro-Nutrients

All fertilizers are not created equal, and using the right blend of nutrients at the right time of year will produce the best results for your lawn. 

Each of the macro-nutrients you see listed on a fertilizers label supports a different part of your grass. Liquid lawn fertilizer at or near a 16-4-8 ratio supports healthy vigorous leaf growth, stimulates roots, and provides your lawn with enough potassium to help it resist disease and stand up to summer’s heat.

I’m a big fan of foliar feeding with a liquid lawn fertilizer, which can often lead to improved nutrient uptake and more visible results in your yard.
