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

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!

Great product

For blueberries and hydrangeas! I can only rate this 4 stars right now as I just now used it! I have used all kinds of acidifiers, granular and liquid trying to change soil acidity just to find out they were only 3 to 30% sulphur! No wonder they never worked! This prilled sulphur is 99%+, the real deal! I used 2 tablespoons per plant from watching a video ! This sulphur from what they say takes 1-6 months to work, applied 2 times a year! Don’t rush or over do it , it can burn roots and kill plants! My advice! Test your soil for acidity and follow package instructions! Good luck! From what I’ve read it is the best to use to lower ph!

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!

Easy to administer, the smell will be off putting but good for the plants. If using on indoor plants, be aware of the smell, it can be overpowering.

Helps my blueberry bushes

My only complaint about these is sort of a big one. Literally. These pellets are large and really solid. Do, even after watering my lawn (new lawn with grass seed) 3-4 times daily, the pellets have not dissolved yet. The next time I need to add sulfur to the soil, I’m using a powder or liquid.
