LESCO Green Flo 18-3-6 Liquid Fertilizer

Fast color now, balanced nutrition over time. Green Flo 18-3-6 combines immediately available nutrition with 50% controlled-release nitrogen (CRN) to reduce surge growth, plus 0.1% iron for a richer, darker green. A dependable, all-purpose liquid you can use throughout the growing season on cool- and warm-season turf.

Why you’ll love Green Flo 18-3-6

• Quick visual response: Foliar-available nutrition and iron deliver fast green-up.
• 50% CRN: Smoother growth curve and extended feeding vs. straight quick-release liquids.
• Balanced N-P-K: 18-3-6 supports color, roots, and stress tolerance in one pass.
• All-purpose use: Great between granular apps, during transitions, or as a light spoon-feed.
• Sprayer-ready: Works with hose-end, handheld, or backpack/battery sprayers.

What’s inside (Guaranteed Analysis)

How to use

1. Choose your sprayer: Hose-end for convenience or backpack/battery sprayer for precision.
2. Mix per label: Dilute with clean water and agitate. Follow label for turf type and application rate.
3. Apply evenly: Walk a steady pace with overlapping passes to avoid striping.
4. Aftercare: Many foliar feeds prefer no irrigation for 4–6 hours to maximize leaf uptake unless the label instructs otherwise.

Typical cadence (guideline)

• Spoon-feeding: Every 2–4 weeks during active growth at low-to-moderate rates per label.
• Between granular apps: Use as needed to maintain color without pushing excessive growth.
• Heat stress periods: Favor lighter rates and evening/early-morning applications.

Rate math note: Exact fluid ounces needed for a target “lbs of N per 1,000 sq ft” depends on the product’s density. Always defer to the label’s fluid-ounce/area guidance.

Tank-mix & compatibility

• Read labels first: Follow the most restrictive label in any mix.
• Jar test: If combining with micronutrients, wetting agents, or pesticides, do a quick jar test to check for separation/precipitation.
• Order of addition: Water → agitation → flowables → emulsifiables → solutions → surfactants last.
• Iron caution: Keep spray off concrete and porous hardscapes to avoid staining.

Coverage

Coverage varies by label rate and spray volume. As a planning aid, many homeowners target ~1 gallon of finished spray per 1,000 sq ft for even coverage with a flat-fan nozzle. Confirm your output during sprayer calibration.

Storage & safety

• Store sealed, out of direct sun, and protect from freezing.
• Wear basic PPE (gloves, eye protection) when mixing and spraying.
• Keep out of reach of children and pets. Follow all label precautions.

Pairs well with

• Granular base fertilizers for season-long feeding
• Backpack & hose-end sprayers for easy application
• Soil amendments to fine-tune pH and soil structure
