Earth Science Fast Acting Sulfur Granules – 5lb – Reduces Soil pH and Nutrient Runoff, Improves Growth & Color for Acid-Loving Plants, Long-Lasting Lawn Care Supplement

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

I have used this product for only 2 months, and my acidic level is improving slowly but surely in my garden.

My pink hydrangeas are now a beautiful shade of blue after just 1 feeding this past spring. This product works.

Whenever your dealing with plants that absolutley need a high acidic level, such as mountain lauels and you need that soil to be quickly fixed, Earth Science delivers. Nobody wants to buy a plant for $50+ and then watch it die for something as easy to fix as PH level. When dealing with citrus, hydrangeas, rhododendron, azaleas and mountain laurel, I always have fast acting sulfur and lime to adjust quickly. Highly recommended.

It works great. My first thought was it doesn't work, but then after a little time, it works just like it says. Be patient!

works well

Great product

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.

Hydrangeas were turning pink now they want to turn blue

Tomatoes don't have bottom rot this year. Might be because of this product.

Je l’ai acheté pour avoir des hortensias bleus mais ils sont toujours roses. J’ai augmenté la dose en voyant les bourgeons roses mais ça n’a pas fonctionné. Je suis déçue de résultat sachant le prix payé.
