Pendelton 18-3-6 With Micro Nutrients
This all-purpose liquid fertilizer provides readily available nutrients with 50% slow-release nitrogen, plus micronutrients to support plant health. Best for homeowners who want steady growth over the season and a balanced approach to turf and ornamentals. Use 3 oz per 1,000 sq ft for turf; for ornamentals, mix 1-2 oz per gallon of water and apply every two weeks. A limitation: higher phosphorus is not included, so soils needing P may require a separate amendment.
Who it’s best for: homeowners seeking a versatile, season-spanning formula with visible nitrogen-driven greening and micronutrients. Why chosen: the product’s slow-release nitrogen helps extend the feeding interval while supporting overall plant vigor.
Key consideration: ensure correct dilution in spray tanks to avoid waste or runoff. Caution: not ideal as a sole source for very phosphorus-demanding turf in poor soils.

This 15-0-15 blend focuses on greening and growth with nitrogen and potassium, plus humic substances, fish, and seaweed. It’s suitable for Bermuda, St. Augustine, Zoysia, tall fescue, fine fescue, and Kentucky bluegrass. Best for: lawns needing a balanced boost that emphasizes vigor and color across seasons. Why chosen: a versatile, all-grass formula that supports lawn hardiness with a blend of organic-like inputs. Limitation: phosphorus is zero, which may not address phosphorus-deficient soils or specific turf needs.

It’s designed for spring and summer use across any grass type, promoting greening, growth, and turf resilience. Best for: lawns needing a nutrient-dense, ready-to-use spray formula with enhanced bioactive inputs. Why chosen: strong nitrogen presence combined with potassium supports color and density. Limitation: nitrate-heavy blends may require careful application to avoid over-fertilization on sensitive grasses.

Petra 28-0-0 Liquid Nitrogen Fertilizer
This 28-0-0 nitrogen-dominant formula targets rapid green-up and vigorous growth with quick-release nitrogen, plus a slow-release portion for ongoing density. Best for: lawns with nitrogen deficiency needing fast recovery or early-season boost. Why chosen: highest immediate nitrogen level among the listed options, which supports rapid turf greening. Limitation: no phosphorus or potassium in this blend, so supplementary nutrients may be required for balanced nutrition and soil health.
Who it’s best for: those seeking rapid nitrogen delivery to stimulate growth quickly. Why: the 70/30 split supports immediate color with steady longer-term growth.
Buying Guide: Key Considerations For 17-0-5 Type Alternatives
- What nutrient balance fits my soil? Consider whether you need more nitrogen for greening or potassium for toughness. A high-N blend may require supplemental P if soil tests show a phosphorus deficit.
- Is the product compatible with my grass type? Some formulas are versatile across all cool-season and warm-season grasses, while others are optimized for specific species.
- What is the application method? Hose-end sprayers, backpack sprayers, and ready-to-use spray bottles vary in ease of use and coverage. Choose based on lawn size and maintenance preferences.
- What is the release profile? Slow-release nitrogen can extend feeding intervals, reducing labor and runoff risk, while quick-release nitrogen delivers rapid greening.
- Are micronutrients included? Some blends add micronutrients or seaweed/fish derivatives that support overall plant health beyond primary NPK.
- What about environmental impact? Look for formulations designed to minimize waste and packaging, and follow label directions to avoid over-fertilization.
- What is the size and coverage? Larger bottles or gallons reduce refills for bigger lawns, but verify the recommended application rate per 1,000 sq ft.
Frequently Asked Questions
- What does 17-0-5 mean in fertilizer terms? It indicates a fertilizer with high nitrogen (N) and negligible phosphate (P) and zero potassium (K). These blends emphasize greening and leaf growth.
- Can I use a high-nitrogen fertilizer on any grass type? Most are suitable for common warm- and cool-season grasses, but always check label guidance for compatibility and seasonal timing.
- How often should I apply liquid nitrogen fertilizers? Depending on the product, every 2–4 weeks is common for lawn needs, with adjustments for growth rate and weather conditions.
- Should I add phosphorus separately if using a high-N fertilizer? If soil tests show phosphorus deficiency, yes; otherwise, a phosphorus-containing product may be unnecessary.
- Is iron included in any of these formulas? Some products add iron to boost deep greening; this can provide a quicker color boost beyond nitrogen alone.
- What safety steps should I follow when applying liquid fertilizer? Always wear gloves, avoid overspray on sidewalks or driveways, and water in after application as recommended on the label.
