Super Nitrogen Liquid Lawn Fertilizer (42.3 fl oz)

When your lawn needs maximum feeding. Large properties where standard formulas don't keep up, bermudagrass that grows aggressively in summer, or high-traffic areas that need constant recovery. Super Nitrogen delivers 30% nitrogen versus 26-28% in other formulas. If your lawn looks hungry two weeks after fertilizing, this delivers more fuel.

Yes. Over-fertilizing causes excessive top growth at the expense of roots, increases disease susceptibility, and can burn grass. Super Nitrogen includes 5.8% slow-release and zinc to reduce burn risk, but follow application rates. Don't apply more often than every 4-6 weeks.

Zinc helps grass process nitrogen efficiently. Without enough zinc, nitrogen builds up faster than the plant can use it, increasing burn risk. The zinc in Super Nitrogen supports healthy uptake so you get the benefits of high nitrogen without the downside.

For established lawns, yes. Bermudagrass, St. Augustine, and other warm-season grasses handle high nitrogen well. Fine fescue prefers less. Kentucky bluegrass tolerates it. Know your grass type before applying. And avoid new seedlings—they need phosphorus, not heavy nitrogen.
