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

Good,pure,and at a amazing price . I used it to make antique muzzle loading propellant. It worked very well and burns pretty clean.

Helps my blueberry bushes

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.

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

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!

Great product

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.

It's sulfur. Good price, shipped fast.
