Liquid Lawn Fertilizer

Instant Results. Precise Feeding.
Spray-on fertilizers for fast green-up, micronutrient boosts, and spoon-feeding control.

Fast color, precise feeding, pro-grade results. Liquid fertilizers are ideal for quick greening, spoon-feeding during stress periods, and dialing in micronutrients without overloading your lawn. Use with a hose-end or backpack sprayer for even coverage and instant results.

Why choose liquid fertilizer?

  • Immediate uptake: Delivers available nutrients fast—perfect for color boosts and in-season corrections.
  • Spoon-feeding control: Apply 0.10–0.25 lb of N per 1,000 sq ft per application to maintain steady growth and color.
  • Micronutrient precision: Target iron, manganese, and other micros for rich, dark green without excessive top growth.
  • Compatible with programs: Liquids layer nicely between granular apps to fine-tune performance.

Pro tip: Many homeowners pair granular base nutrition (for season-long feeding) with liquid touch-ups (for quick color and micronutrients). It’s the best of both worlds.

When liquids shine

  • Between granular feedings: Keep color without pushing too much growth.
  • Summer stress: Light liquid feed + iron can sustain color while heat is high.
  • Micronutrient corrections: Quickly address chlorosis and pale color with foliar iron & manganese.
  • New turf care: Gentle, low-rate liquids support seedlings without coating the soil with excess granules.

How to apply

Hose-End Sprayer

  1. Fill sprayer with the recommended amount of product and water.
  2. Set to the label’s dilution rate; spray in a steady, overlapping pattern.
  3. Typical target: 1.0–2.5 gallons of finished spray per 1,000 sq ft (check label).

Backpack / Battery Sprayer

  1. Calibrate your walking pace and nozzle to achieve your target output (e.g., 1 gal/1,000 sq ft).
  2. Mix concentrate with water per label. Agitate/mix thoroughly.
  3. Spray in light, even passes to avoid striping.

Water-in? Follow the label. Many foliar-focused liquids prefer no irrigation for 4–6 hours to maximize leaf absorption. Nitrogen sources that are soil-active may recommend a light watering-in.

Suggested liquid application cadence

Cool-Season Lawns (Tall Fescue, Kentucky Bluegrass)

  • Spring & Fall: Every 2–4 weeks at 0.10–0.25 lb N/1,000 sq ft as needed for color.
  • Summer: Favor low-N + iron sprays to maintain color without surge growth.
  • Winter: Use micronutrients/iron on warmer days above label temp minimums.

Warm-Season Lawns (Bermuda, Zoysia, St. Augustine)

  • Active growth (late spring–summer): Every 2–3 weeks at 0.10–0.25 lb N/1,000 for steady color.
  • Transition months: Lean on iron + micros to deepen color without thatch-building growth.
  • Dormancy/slow growth: Skip N; use micronutrients judiciously per label and temperatures.

Quick Rate Cheat Sheet

Goal Typical Target Notes
Spoon-feed Nitrogen 0.10–0.25 lb N per 1,000 sq ft Every 2–4 weeks in season
Fast Color (Iron) Per label (often 2–16 oz/1,000) Avoid staining; keep off concrete
Micronutrients Blend Per label (foliar focus) No irrigation 4–6 hrs unless stated

Tank-Mix & Compatibility Tips

  • Read labels first: Follow the most restrictive label.
  • Jar test: If unsure, combine small amounts in a jar to check for clumping/precipitation.
  • Order of addition: Water → agitation → compatibility agent (if used) → powders → liquids → surfactant last.
  • Mind pH & hardness: Very hard/alkaline water can reduce availability—conditioning can help.
  • Avoid staining: Iron can stain concrete and porous surfaces. Rinse promptly.

Frequently Asked Questions

Is liquid fertilizer better than granular?

They do different jobs. Granular excels at season-long feeding and building the base. Liquids are perfect for quick color, micronutrients, and precise low-rate spoon-feeding. Many homeowners use both.

How often can I spray?

During active growth, every 2–4 weeks at 0.10–0.25 lb N/1,000 is common. For iron/micros, follow the label—often every 2–3 weeks or as needed.

Will liquid fertilizer burn my lawn?

At proper dilution and rates, liquids are very safe. Always follow the label, avoid high-heat hours, and keep the sprayer moving to prevent over-application.

Can I mix iron with other liquids?

Often yes, but do a jar test and follow label compatibility notes. Apply carefully to avoid staining hardscapes.

What’s the best nozzle/output?

A flat-fan nozzle delivering about 1 gal per 1,000 sq ft is a great starting target for even coverage. Calibrate your sprayer once—it pays off all season.
