A convenient liquid feed with a real complication for a lot of readers: the 4 in the middle is phosphorus, and seven of the states we cover restrict phosphorus lawn fertilizer.
Good as a light, fast, even feed and mediocre as a season's fertility programme. Liquid concentrates like this go on through a hose-end applicator with no spreader calibration, they green up quickly because a share of the nitrogen is immediately available, and at roughly 3,200 sq ft per bottle they suit small lawns and touch-ups. Two honest limits. Liquids at this rate deliver much less total nitrogen per application than a granular feed, so you are on a shorter reapplication cycle — read our fertilizer arithmetic before assuming one bottle is a feeding. And it contains phosphorus, which matters legally rather than agronomically in much of the country: Washington, New Jersey, Michigan, New York, Virginia, Minnesota and Wisconsin all restrict phosphorus lawn fertilizer by statute, and most established lawns do not need added phosphorus unless a soil test says so.

When to fertilize a lawn: autumn matters more than spring for cool-season grass, the reverse for warm-season — plus the state laws that close the window.
