Farmer's Secret Greenup Fertilizer - Super Concentrated and Fast Acting - High Nitrogen Fertilizer Plus Sugar for Fast Shot of Green for All Types of Lawns and Turfs (32oz)

What It Is

This is a liquid lawn fertilizer concentrate (32 oz) designed for spray application on all turf types. It delivers a fast-acting nitrogen boost plus sugar to stimulate microbial activity and green up grass within days.

Fitment & Compatibility

No mower model or brand fitment needed—this is a universal lawn treatment. Before buying:

• Sprayer type: Works with any hose-end sprayer, backpack sprayer, or pump sprayer. Not compatible with granular spreaders.
• Coverage: 32 oz treats up to 2,500 sq ft at the recommended rate (1 oz per 80 sq ft). Measure your lawn area to ensure you have enough.
• Application timing: Best applied when grass is actively growing and soil temperature is above 55°F. Avoid use on dormant or stressed lawns.
• Nitrogen content: High nitrogen formula (check label for exact N-P-K). Do not use on newly seeded lawns until after second mowing.

Key Things to Know

• Super concentrated: Mix at 1 oz per gallon of water. Over-application can burn grass—use a measuring cup, not guesswork.
• Fast results visible in 3-5 days, but the “sugar” component may attract ants or bees temporarily if left on hard surfaces.
• Not a complete fertilizer: Provides only nitrogen and sugar; lacks phosphorus and potassium. Use as a quick green-up shot, not a balanced feed.
• Shelf life: Store tightly sealed in a cool, dry place. Can crystallize in cold temps—warm to room temp and shake before use.

Should You Buy It

Good if you need a rapid green-up for an event or to fix yellow patches, and you already have a balanced fertilizer program. Skip it if you want a single, complete lawn food or if you’re on a tight budget—the 3.8 rating suggests mixed results on some turf types.
