The Andersons Premium New Lawn Starter Fertilizer 20-27-5 18 lb — High-Phosphorus Starter with Slow/Quick-Release Nitrogen

The Andersons Premium New Lawn Starter 20-27-5 is a specially balanced starter fertilizer formulated to help newly seeded or sodded lawns develop strong roots and healthy green growth.

Designed for turf establishment, this 18 lb bag covers up to 5,000 square feet and delivers a high-phosphorus blend (20-27-5) with both quick- and slow-release nitrogen and added micronutrients. It supplies the nutrients young seedlings need to germinate vigorously and push out deeper roots, while 1% iron contributes to richer color. Safe for use on all turf types, it’s intended for spring or fall applications when starting fresh lawns or overseeding thin areas.

How does this starter fertilizer support root development?

The elevated phosphorus (27%) is the key component for encouraging early root establishment, helping seedlings anchor and take up water and nutrients more efficiently. Balanced nitrogen supports initial top growth without overwhelming delicate new shoots.

• High available phosphorus promotes strong root systems.
• Quick-release nitrogen gives immediate feed for seedling growth.
• Slow-release nitrogen provides steady nutrition over weeks.
• Essential micronutrients and iron aid seedling vigor and color.

When and how should I apply it to newly seeded or sodded areas?

Apply at the time of seeding or immediately after laying sod for best results. Use a broadcast or drop spreader for even distribution, water lightly to move nutrients into the soil, and follow recommended rates for the 5,000 sq ft coverage.

• Apply at seeding or right after sod installation.
• Use a calibrated spreader for consistent coverage.
• Water after application to activate nutrients without runoff.
• Avoid applying during drought or before heavy rain to prevent wash-off.

What makes this product different from a regular lawn fertilizer?

Starter fertilizers are formulated with a higher phosphorus ratio to prioritize root growth rather than only promoting blade development. This product also combines quick- and slow-release nitrogen, so new lawns receive an immediate nutrient boost plus sustained feeding as roots establish.

• Higher phosphorus tailored to root initiation.
• Dual-release nitrogen for immediate and lasting nourishment.
• Includes 1% iron for deeper greening without excess nitrogen stress.
• Formulated specifically for new turf, not routine maintenance feeds.

Is it safe for different grass types and seasonal use?

Yes—this starter is suitable for all common turf varieties and is typically used in spring or fall when temperatures favor germination and root growth. Follow label directions for best timing and application rates to avoid overfeeding.

• Safe for warm- and cool-season grasses when used as directed.
• Recommended for spring and fall seeding or sodding projects.
• Check local guidelines for optimal seeding calendars and watering.
• Apply according to coverage to prevent nutrient runoff and waste.

Who this product is for: Homeowners, landscapers, and groundskeepers launching new lawns or repairing large bare patches who want a reliable, nutrient-focused starter feed. If you’re seeding or laying sod up to about 5,000 sq ft and need a product that encourages solid root systems, consistent early growth, and improved color, The Andersons Premium New Lawn Starter 20-27-5 is formulated to meet those needs without excess complexity.
