DGL Dark Green Lawn 25-0-0 Fertilizer - Fast Green-Up for 5,000 sqft

Our review of the DGL Dark Green Lawn 25-0-0 Fertilizer finds it best for homeowners and landscapers who want a quick visible green-up without added iron. The single biggest reason to buy is its extremely fine particle size that delivers very even coverage and immediate feeding from all quick-release nitrogen, producing noticeable darkening of turf within days while remaining safe for all turf types.

Key Features

• Fine particle size: The extremely fine granules spread evenly, reducing streaks and improving coverage across a 5,000 sq ft application.
• Quick-release nitrogen: Contains all quick-release nitrogen for an immediate boost in color and growth visible within a few days.
• Iron-free formula: The updated formula does not include iron, so it darkens turf without causing iron stains on walkways or hard surfaces.
• Supplement use: Can be applied at the light rate to supplement other fertilizer programs for targeted feeding when needed.
• Safe for all turf: Labeled safe for all turf types, making it a versatile option for mixed lawns or professional applications.
• Made in the USA: Manufactured domestically, which may appeal to buyers preferring locally produced lawn products.

Who It's For

This fertilizer is well suited to homeowners, property managers, and lawn care professionals who need a fast-acting nitrogen feed to quickly improve turf color and fill in thin areas. The fine particle size makes it a good pick for those who value even distribution and want to avoid the patchy look some granular products produce.

It is less appropriate for users specifically seeking slow-release nitrogen or iron-based colorants; if long duration between applications or a deep iron-driven green is the goal, consider a slow-release blend or an iron supplement instead.

Pros & Cons

Pros

• Very fine particle size for uniform coverage and fewer application streaks.
• Immediate feeding from quick-release nitrogen produces visible greening within days.
