Earth Science Fast Acting Sulfur Granules – 5lb
Fast Acting Sulfur granules start reducing soil pH quickly, helping acid-loving plants such as hydrangeas, azaleas, and blueberries absorb nutrients more effectively. This small 5-pound bag is suitable for medium lawns or targeted patches. The product emphasizes improved growth, stronger color, and reduced fertilizer runoff, making it a practical starter option for homeowners addressing alkaline soils.
The Andersons Elemental Sulfur pH Down – 40 lbs.
Designed for lawns with high pH, this granular sulfur product balances soil acidity to support optimal turf health. The prilled format allows tidy, even application, and it is safe for use on all turf types. A non-burning formula enables application at various times, aiding turf managers seeking flexibility in maintenance schedules.
Earth Science Fast Acting Sulfur (25 lb.)
This 25-pound bag provides substantial coverage for larger lawns or multiple beds needing pH adjustment. As a granular prill, it distributes evenly to support nutrient uptake and improved plant coloration. It is positioned as a practical, long-lasting option for ongoing soil treatment and turf health.
Superior 15-0-15 Liquid Lawn Fertilizer
This all-season liquid fertilizer blends nitrogen and potassium with humic substances, fish and seaweed. It promotes uniform greening, faster growth, and greater turf hardiness across all grass types. The included sprayer attachment simplifies application, making it convenient for users seeking quick, even coverage without granular handling.
Elemental Soil Acidifier Sulfur Pellets (50 Lbs.)
A 50-pound supply of high-purity elemental sulfur pellets, designed for lawns, shrubs, trees, and pre-planting soil preparation. The pellets are described as dust-free and uniform, simplifying spread consistency. This product supports broad soil acidification goals across multiple landscape applications.
Buying Guide: Sulfur-Related Lawn Fertilizer Considerations
- Soil pH testing: Start with a recent soil test to confirm pH levels and determine how much sulfur is needed. Excess sulfur can lower soil pH beyond optimal levels for some plants.
- Form factor: Granular sulfur is typically slower to react but provides longer-lasting pH adjustments. Liquid formulas act faster and are useful for quick greening, but may require more frequent applications.
- Target plants: Acid-loving plants (hydrangeas, azaleas, blueberries) benefit more from sulfur-based amendments. For general turf health, balanced products that include essential nutrients may be preferable.
- Application rate and coverage: Check product label for coverage per bag and recommended spread rates. Mismatched rates can cause uneven color or turf damage.
- Wear and safety: Sulfur products can irritate skin and eyes; use gloves and avoid inhalation during application. Store in a dry, cool place away from children and pets.
- Long-term strategy: Combine sulfur amendments with proper nutrient management (nitrogen, potassium) and aeration to sustain a healthy lawn ecosystem.
- Environmental considerations: Avoid over-application near water sources to minimize runoff. Use slow-release formulations where possible to reduce nutrient leakage.
