With 20% iron content, this formula helps address iron deficiency in alkaline soils and aims to enhance the green appearance of lawns, shrubs, trees, and edible gardens. The product is a water‑soluble powder, simplifying incorporation into your routine and encouraging quick root access to nutrients.\u003c\/p\u003e\n\u003ch3\u003eHow it works\u003c\/h3\u003e\n\u003cp\u003eFerrous sulfate acts as both a soil conditioner and iron source, potentially aiding nutrient uptake when conditions are right. In alkaline soils, it can help lower pH levels enough to improve availability of essential elements for many plants. The composition includes 20% Iron (Fe) and 12% Sulfur (S), contributing to a balanced micronutrient profile that dissolves in water for root access.\u003c\/p\u003e\n\u003ch3\u003eKey product details\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003e20% iron (Fe) and 12% sulfur (S) for a focused micronutrient boost\u003c\/li\u003e\n  \u003cli\u003e99%+ water soluble powder for easy mixing and distribution\u003c\/li\u003e\n  \u003cli\u003eBest used in the morning hours when temperatures are cooler\u003c\/li\u003e\n  \u003cli\u003eCan help condition soil and support nutrient availability in some soil types\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eHow to use\u003c\/h3\u003e\n\u003cp\u003eDirections cover flowers, shrubs, trees, vegetables, and lawns with specific rates.

To acidify soil, use 0.5 to 1 lb per 100 sq ft, with lower rates on sandy soils and higher rates on heavy soils.
