True Organic Prilled Sulfur – Organic Fertilizer for Better Plant Growth, Flowers, Vegetables, and Herbs – Lowers Soil pH – 5lb Bag Covers 1,333 Sq. Ft.

The stuff is awesome. Smells like a big pack of matches LOL. You get a lot for your money and it's super easy to apply. My blueberries are happier than they have ever been. It says you should put it in the soil a month or so before planting the blueberries but I put it in after planting them. Still worked great. Just mix the little pellets in with the soil and let it do its thing! Great for any acidic loving plant

Needed this product ASAP for a couple of blueberries I have potted in large containers in my garden. Their leaves gave The Telltale sign that they were into alkaline of soil. This pelletized product was very easy to apply and work into the top three inches. Will return to give an update on how my plants improve.

Great for bringing down ph in biochar or in alkaline soils. Helps the microbes in the soil break down and consume organic matter for easy accessibility to feed plants. Very effective

So far so good! Works for the blueberry plants

They take a long time to break down, so use well before growing season.

Works really well for my blueberries. I used it to help lower the soil pH, and my plants look healthier already. Easy to apply and lasts a long time. Would definitely buy again!

Seems to be a good product. I would buy again. (And probably have to because we have clay soil with high pH.) My only note is to pay attention to all of the images they provide. The title says “5lb Bag Covers 1,333 Sq. Ft.” So you think “that’s a lot of square feet!” But if you keep flipping through the pictures they provide, you will see the chart about how much you need to shift the dial on pH based on the type of soil you have. For example, sandy soil may take 2 lbs (or 3ish cups). But clay soil will take 8.5 lbs (or 13ish cups) to see the same degree of change as the 3ish cups for sandy soil. But if you want vegetables bigger than ping pong balls, we’ve gotta do what we’ve gotta do. Bring on the sulfur!

I'm very pleased with this sulphur soil additive. It consists of small, disk-like pellets that are easy to handle and spread. I have a small area to treat so I disperse it by hand, but I expect it would be fine in most broadcast spreaders for larger area coverage. The pellets are bright yellow (as you would expect from sulphur) so it's easy to check for even coverage when spreading by hand. There's no appreciable dust when handing it, which is a plus. It's been working great to decrease the pH of an area that is too alkaline. The cost per pound is excellent, and well below other similar options. Five stars.
