Grow More 100% Soluble Fertilizer Concentrate
High phosphorus and potassium formula supports root development and bloom production. The product is described as nutrient-rich with chelated minerals such as iron and zinc to improve uptake, particularly during flowering and fruiting phases. Best for gardeners focusing on strong blooms, larger fruits, and root development in flowering crops. Choose this if your priority is robust flowering and fruiting rather than immediate lawn greening.
Best for: flowering plants and vegetable crops during transplanting or bloom phases. Limitation: lacks nitrogen emphasis for quick top-growth; not the best option for rapid lawn greening without supplemental nitrogen.
Yard Mastery 24-0-6 Flagship Granular Lawn Fertilizer
This all-purpose lawn fertilizer delivers a balanced 24-0-6 NPK ratio with 3% iron and micronutrients. It features a slow-release formula designed for steady nutrient supply over time, reducing the need for frequent applications. It’s best for maintaining year-round lawn health, with improved root strength and color. Use this when you want long-term green growth and fewer applications, especially on lawns that benefit from iron supplementation.
Best for: lawns needing sustained growth and iron-enhanced color. Limitation: no phosphorus for flowering crops; not ideal for bloom-focused plant feeding.
The Andersons Core 24-6-12 Professional-Grade (45 lb)
With a precise 4:1:2 ratio, this fertilizer supplies nitrogen for quick growth and sustained feeding, alongside iron and micronutrients for total nutrition and deep greening. The product uses super-fine particles for even distribution and is suitable for all turf types across seasons. Best for homeowners seeking a reliable, all-season turf booster with balanced nutrition. A potential limitation is the need for regular reapplication every 4-6 weeks for optimal results.
Best for: all-turf lawns needing even distribution and long-lasting feeding. Limitation: requires periodic reapplication to maintain color and growth.
The Andersons Core 24-6-12 (18 lb)
This smaller bag mirrors the same 24-6-12 formula as the larger option, offering convenient portioning for smaller lawns or patch treatments. It contains iron and micronutrients for total nutrition and supports quick greening with long-lasting effects. Best for: homeowners with smaller yards or those who prefer incremental applications. Limitation: smaller bag may require more frequent purchases for larger lawns.
The Andersons Deep Green 24-0-11 (Professional-Grade)
Designed to intensify turf color and minimize yellowing, this 24-0-11 formulation includes iron and manganese to support chlorophyll production. It features both quick- and slow-release nitrogen for immediate growth and extended feeding, up to eight weeks. Best for: lawns needing strong color and stress resistance during hot months. Limitation: no phosphorus means limited bloom support if you’re also growing flowering plants in neighboring beds.
AgChimp 24-0-11 Professional Lawn Maintenance Fertilizer
This 24-0-11 blend emphasizes quick- and slow-release nitrogen for immediate greening and sustained growth. The dual-phase feeding system supports rapid turf lift while preventing spikes that can lead to burn. Best for: residential lawns needing fast green-up with ongoing maintenance. Limitation: not optimized for flowering plant feeding; primarily lawn-focused.
Buying Guide: What to Consider When Choosing Fertilizers
What should the NPK4 balance tell you?
NPK numbers indicate nitrogen, phosphorus, and potassium content. High nitrogen (N) supports rapid green growth, high phosphorus (P) supports root and flowering strength, and potassium (K) supports overall plant health. For bloom-heavy plants, look for higher P and K. For lawns, balanced or higher N is common, with iron supplements for color.
Is slow-release fertilizer preferable?
Slow-release formulas provide a steady nutrient supply, reducing the risk of burn and requiring fewer applications. They’re especially useful for lawns and established beds. Quick-release nitrogen gives fast greening but can cause growth bursts if over-applied.
What about micronutrients and micronutrient balance?
Micronutrients such as iron, zinc, manganese, and boron improve color, root quality, and resilience. Chelated micronutrients are easier for plants to absorb, particularly in challenging soils or during stress.
Bag size and coverage considerations
Smaller bags are easier to manage for patches or small lawns, while larger bags suit bigger yards. Consider season length, reapplication intervals, and your spreader’s capacity to ensure even coverage and cost efficiency.
Best-use scenarios by product type
- Bloom-focused nutrition: Grow More 6-30-30 for roots and blooms, with caution about nitrogen levels for leafy growth.
- Lawn color and longevity: The Andersons 24-6-12 options and GreenView 24-0-6 work well for all-season green growth and weed-friendly feeding.

FAQ
- What does 6-24-24 mean?
It indicates a fertilizer with 6% nitrogen, 24% phosphorus, and 24% potassium. While none of the listed products use exactly 6-24-24, several offer strong phosphorus and potassium combinations suitable for blooms and root development. - Should I choose slow-release nitrogen?
Yes for lawns and long-term feeding. It reduces burn risk and lowers application frequency. - Is iron supplementation important?
Iron improves color and chlorophyll production in greens. If your lawn shows yellowing, iron-bearing formulas can help. - Can I use lawn fertilizers on garden beds?
Generally not ideal; lawn formulas emphasize rapid turf growth and can oversupply nutrients to flowering beds. Use bed-specific or all-purpose formulas when feeding vegetables or flowers. - How often should I reapply?
Most turf fertilizers suggest reapplication every 4-6 weeks during the growing season, depending on product instructions and lawn conditions.
