Organic Blood Meal Fertilizer 12-0-0 - All-Natural Nitrogen Boost

Our review of Gardenera's Organic Blood Meal Fertilizer finds it best suited to gardeners seeking a strong, natural nitrogen source for leafy growth. The single biggest reason to buy is its concentrated 12-0-0 formula that reliably supplies nitrogen to vegetables, flowers, trees and shrubs without synthetic additives. Used as directed, this blood meal encourages rapid vegetative growth and new shoots, making it a practical choice for organic gardeners who want a straightforward, all-organic way to correct nitrogen deficiencies.

Key Features

• All-organic nitrogen source: The 12-0-0 formulation supplies a concentrated dose of nitrogen to support vigorous leaf and stem growth.
• Versatile use: Suitable for vegetables, flowers, trees and shrubs, it can be used across a home garden to boost green growth where needed.
• Approved for organic production: The product is presented for use in organic gardening, helping maintain an organic growing program.
• Rapid action: Blood meal is known for fast availability of nitrogen, which can quickly show new growth and greener foliage.
• Generous packaging: The 20 quart size provides enough product for multiple feeding cycles on beds, containers and established plants.

Who It's For

This blood meal is a good match for home gardeners and small-scale growers who need an effective, organic way to increase nitrogen and improve vegetative vigor in leafy vegetables, annuals and shrubs. It especially suits those who prefer clear, single-ingredient organic fertilizers rather than complex blends.

It is less useful for gardeners who need balanced N-P-K feeding for flowering or fruit set, since this is a straight nitrogen source (12-0-0). Those looking for slow-release, multi-nutrient formulas or a product to correct phosphorus or potassium deficiencies should look elsewhere.
