About 4-4-4 Organic Granular Fertilizer

Mirimichi Green 4-4-4 organic granular fertilizer is OMRI Listed and made from high-quality natural inputs that make plants more self-sustainable. By removing consistent synthetic fertilizer feedings, the plant finds what it needs in the soil and consumes the easily digestible organic fertilizer nutrients. All of the nutrient-rich ingredients and value-added biologicals enhance plant growth and vigor by optimizing nutrient availability and uptake. Feather meal provides a rich, natural source of nitrogen for greener leaves and overall plant growth. Composted poultry manure is high organic matter and contains nitrogen, calcium, phosphorous, and potassium to improve soil structure and create a well-balanced nutrient offering to the plant.

Not only does Mirimichi Green 4-4-4 organic fertilizer have macronutrients, it also has soil-enhancing biology to create a nourished and peak-performing ecosystem to work the way nature intended. The colonies of Bacillus bacteria, Mycorrhizal fungi, and Trichoderma fungi work together around the plant’s rhizosphere and grow close to the root to promote healthy growth.

What Customers Say About 4-4-4 Organic Granular Fertilizer

Great product! It all starts with your fertilizer, high quality fertilizer will give you high quality results.

Grant K.✓ Verified August 31, 2026 · 50 lb. Bag

My grass has greened up nicely from this. The balance of nutrients and slow release nitrogen from the chicken manure has been a great organic way to keep my soil and grass happy. I'm also glad I found this since I have kids playing in the yard and I don't want to use synthetics.
