Description

Fast Acting Sulfur works immediately to lower the pH of your soil, which helps acid-loving plants like hydrangeas, azaleas, and blueberries absorb more food, and improves fertilizer effectiveness. Helps green up lawns and create colorful blooms. Naturally lowers soil pH to help plants absorb more food. Great for hydrangeas, azaleas, blueberries, and other acid-loving plants. Earth Science’s patented Nutri-Bond Technology bonds with the soil to help keep more product where you put it. That’s better for the environment and helps your lawn or garden get the most out of every application. Apply at a rate of 5 lbs per 1,000 Sq. Ft. One bag of Earth Science Fast Acting Sulfur will cover a 5,000 Sq. Ft. lawn. Apply any time of year to maintain optimum soil pH. While not required, watering for 15 minutes after application activates the product for faster results. Tip: For improved success, test your soil pH annually and be sure to search for your specific location to find the ideal pH level. People and pets can use the lawn immediately after application. 25 years ago, we started The Earth Science Company based on a commitment to grow healthier lawns and gardens the way nature intended. Lawns weren’t meant to cosmetically green up overnight and we shouldn’t eat vegetables twice their natural size. The thinking behind everything we do is simple – let nature do its thing. Our role is to support nature, not force it to become something it’s not. We believe the most important part of growing strong, beautiful plants is healthy soil. That’s the foundation for every product we create. Our products are rich in organics to restore and condition depleted soils and sustainably made without any harmful chemicals or pesticides. We balance technology with biology in ways that are not only friendly to the things that grow in the ground, but those on top of it too. Because when it comes to growing beautiful plants, you truly get out of it what you put into it.

  • Garden saver for a level of 15+ on an acid scale!
Size: 5 lbs.
This stuff literally saved my garden!! Everything stunted due to my well water. The acid levels were way too high and this is how I brought them back down. About a week after I added it I noticed a difference and a couple weeks later My flowers started to bloom. Now I have the most beautiful garden. The smell is not bad and I like the color, makes it easy to see the little pebbles. I love how much you get in the bag! Definitely will be buying again! ... show more

  • Good Product
Size: 5 lbs.
Works great for acidic loving plants, turned bigleaf hydrangeas from pink/red to blue like we wanted, don't really know if it helps with plant growth (it does not hurt growth), easy to use, great value, yellow color, doesn't stain skin, nice appearance for storing on shelf

  • Doesn't take the place of organic soil enrichment.
Size: 2.5 lbs.
Gardening on any scale is an art of patience as it takes years to enrich the chain of soil. For years I haven't thrown away leaves and put kitchen scraps out every day. Eventually I began to use only rainwater. These measures led to a fairly balanced PH good enough to grow any vegetable we need. Just in case in the future if we need organic sulfur at low levels using this product at much lower doses may suffice. First we would have to run out of organic matter the worms and insects enjoy as they also produce some sulfur. ... show more

  • IT WORKS
Size: 5 lbs.
I have used this product for only 2 months, and my acidic level is improving slowly but surely in my garden.

  • Good product but slow. And PH reduction not enough
Size: 5 lbs.
I’ve used this now for more than two weeks and indeed the pH does come down a little, but not in the amount that they make you think it’s going to. Moss is the quickest way to bring it down but even using moss with this you still don’t get it down far enough where fruit trees, vegetables and herbs like to be: 5.5 through 6.5 HP. It’d be great if this thing could do a better job faster to bring down the HP by making it more acidic without harming plants. ... show more
