Product Description
Lower high soil pH and help your lawn use nutrients more effectively. Soil Acidifier contains 90% elemental sulfur and is designed to gradually correct high-pH soil. When soil pH is too high, grass may have trouble using nutrients already present in the soil, which can lead to weak growth, pale color, and poor lawn performance.
Use this product only when a soil test confirms that your pH is above the recommended range for your grass type.
Why Choose Soil Acidifier?
- Lowers High Soil pH: Helps gradually correct alkaline soil conditions.
- Improves Nutrient Availability: A properly balanced pH helps grass roots access fertilizer and soil nutrients more efficiently.
- Supports Better Lawn Color: Correcting high pH may help improve yellowing caused by nutrient lockout.
- 90% Elemental Sulfur: Provides a concentrated sulfur source for long-term soil pH correction.
- Pelletized Formula: Easy to spread evenly with a fertilizer spreader.
Best Uses
- Lawns with a soil test confirming high pH
- Correcting soil conditions that reduce nutrient availability
- Improving long-term lawn color and performance
- Bahia, Centipede, Bermuda, St. Augustine, and Zoysia lawns
- Landscape beds and acid-loving plants
Application Rate
Always test your soil before applying. The amount needed depends on your current soil pH and the pH you are trying to reach.
Lawns, Turf & Pastures: Apply 10–15 lbs per 1,000 sq ft for each one-point reduction in soil pH.
Example: If your soil pH is 7.0 and your target pH is 6.0, apply 10–15 lbs per 1,000 sq ft.
- Do not make more than 3 applications per year.
- Wait at least 2 months between applications.
- Apply when the grass is dry.
- Spread evenly with a fertilizer spreader.
- Water thoroughly after application.
Landscape Beds & Gardens: Apply 10 lbs per 1,000 sq ft for each one-point reduction in soil pH. Apply beneath the plant canopy out to the drip line, then water thoroughly.
Important: Elemental sulfur works gradually and will not lower soil pH immediately. Retest your soil before making another application. Do not apply more than the label recommends in an attempt to speed up the process.

Q&A
- My lawn is 4700 square feet. I use a lesco rotary spreader. What is correct setting for my lawn here in Massachusetts.
- https://lawnsynergy.com/pages/spreader-settings
- My soil was tested by my local Cooperative extension and was Nitrogen depleted, Phosphorous deficient, and in the sufficient range for Pottassium. Their recommendation was to add Sulfur, but specifically cautioned not to apply in the summer. Is there a fertilizer designed for these conditons that can be applied right now
- I would suggest taking a look at our 5-3-0 BioBoost Organics
- What would be the broadcast settings for this product for the Echo RB-60? Thank you!!
- A Setting of 5-6 should be sufficient. However it is approximate depending on the amount of lbs per 1,000 sqft, walk speed, spread distance, etc. Always use your best judgement and portion off the bag to areas of your lawn so that it is more accurate and you apply the correct amount of lbs/1,000 your aiming for.
- I have bought blueberry plants recently and are waiting to be planted but I found out my current soil PH is 6.65. I need to bring down soil ph to 4.5 to 5.5 level. For which I need to apply elemental Sulpher but I am not sure weather your product is suitable for such use. If it can be applied kindly let me know your price per kg and how to apply for such use.
- Yes, soil acidifier is sulfur which will lower the pH of the soil over time. You can mix it in with your soil and it will begin working. It's safe for both lawns, gardens, and landscapes.
