Frequently Asked Questions
What is elemental sulfur and why is it important for organic gardening?
Elemental sulfur, also known as brimstone, is a naturally occurring element (S) that's essential for all living organisms. In organic gardening, sulfur serves multiple critical functions: it's a vital nutrient for plant growth, helping form proteins and enzymes; it naturally lowers soil pH for acid-loving plants; and it acts as an organic fungicide and pest deterrent. Unlike synthetic alternatives, elemental sulfur is approved for organic gardening and works in harmony with soil biology.
How long does it take for sulfur to lower soil pH?
Elemental sulfur typically takes 2-8 weeks to begin lowering soil pH, with full effects visible within 3-6 months. The speed depends on several factors: soil temperature (works faster in warm soil above 55°F), moisture levels (requires adequate water), particle size (finer powder works faster), and soil bacteria activity. For best results, apply sulfur in spring or fall when soil is moist and temperatures are moderate.
Is sulfur safe for pets and wildlife?
When used as directed, elemental sulfur is generally safe around pets and wildlife. It's a naturally occurring element that's less toxic than many synthetic alternatives. However, precautions should be taken: keep pets away during application to prevent inhalation of dust; water thoroughly after application to settle the powder; store in a secure location away from curious pets. While sulfur effectively repels many pests, it doesn't harm beneficial insects like bees when used properly.
Can I use sulfur and lime at the same time?
No — do not apply sulfur and lime together or within 2-3 weeks of each other. Sulfur lowers pH while lime raises it, so using both simultaneously will neutralize their effects and waste product. Always test soil pH before application to determine which amendment you actually need.
How much sulfur do I need to lower pH by 1 point?
The amount varies by soil type. Sandy soils require approximately 10 lbs per 1000 sq ft to lower pH by 1 point. Loam soils need about 12 lbs per 1000 sq ft. Clay soils require the most — around 15 lbs per 1000 sq ft. Use our calculator above for precise amounts based on your specific situation.
