20 lb. Fast Acting Sulfur is rated 4.5 out of 5 by 14.
Rated 4 out of 5 by from Great product served purpose to help plants that require acidic soil to grow and thrive. should consider having product available in-store
Date published: 2013-06-25
Rated 5 out of 5 by from Just what you need when your Ph is 8. Here in Southern California where both the water and the soil have a Ph between 7.5 and 8 this is just what my garden needed. I apply this the same time I put down compost and feed with molasses. This process has made my garden greener. Just look at the cabbage I grew!

Rated 5 out of 5 by from Glad I found it. I have ten thousand square ft. of centipede grass that likes to grow in a acid environment of about 4 to 5 on the P.H. scale. This was the easiest and least expensive way to get the job done. worked great. Two bags will move the P.H. about one full number on the scale.

Rated 5 out of 5 by from works as promised. it worked on trees in the one of the more exclusive parts of town. The noticeable response from the trees was considerably faster than the stuff I was getting at the local hi-end nursery. Getting the pH right enabled the trees to absorb the iron and nitrogen that had been "tied up" in the soil. We were rewarded w/ darker, healthier leaves made more noticeable by the neighbor's foliage on either side.

Rated 1 out of 5 by from Does not work This product is only 50% sulfur, the other half is something that they call AST. This is visible when looking at the product. There are gray pellets and yellow pellets. Obviously the yellow pellets are the sulfur. Two months after application, the grey pellets have disappeared but the yellow pellets containing the sulfur are still intact on top of the soil.

Rated 5 out of 5 by from Great product for lower pH of soil This product does a good job of lowering soil pH and comes in a convient 10,000 sq. ft. coverage bag. I would recommend this product for anyone looking to lower the soil pH.

Rated 5 out of 5 by from Sulfur I use sulfur to maintain the deep blye in my hydrangea bushes. Home Depot on-line was an efficient method rather than shopping at the mall etc.

Rated 4 out of 5 by from 20 lb fast acting sulphur Ordered the prodcut on line for delivery to the store. That went well and was very easy. The product was easy to put down. It is too early to see if it lowered the PH and helps clear up the chlorosis in my oaks and maples. The spring time will tell for sure. I plan on putting more down after winter.
