Simple Lawn Solutions Ultimate 3-18-18 NPK Liquid Lawn Food
My top pick as the best all-around 3-18-18 liquid lawn fertilizer, Simple Lawn Solutions is a solid choice for most users.
This liquid fertilizer comes with a hose-end sprayer and is designed to cover up to 3,200 sq feet. It’s the best option for most homeowners with a small lot and no room for extra equipment (all you need is a hose).
Homeowners with larger properties may want to buy a larger volume and apply with a backpack sprayer.

Why Macro-Nutrient Ratios Matter
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 3-18-18 ratio supports vigorous root growth and helps maintain the overall health and well-being of your lawn.
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.
Important Note: Phosphorus runoff poses a threat to water quality. In certain states, the application of phosphorus-containing fertilizer on lawns or turfgrass is restricted or prohibited. Check your local laws prior to purchase, and give some thought to whether your yard actually requires application of a fertilizer high in phosphorus. Always apply these products responsibly, and dispose of any excess fertilizer in the proper way by contacting your local household hazardous waste disposal facility.
