Sulfur helps with flavonoids in plants increasing aromas
First and foremost, the fact that it's OMRI certified gives me peace of mind knowing that I'm using a product that's not only effective but also environmentally friendly and safe for my plants. As someone who values organic gardening practices, this is a big win for me. But let's talk about performance. This potassium sulfate is a powerhouse when it comes to boosting plant growth and overall health. I've noticed a significant difference in the vigor and vitality of my plants since incorporating it into my fertilization routine. From improved root development to stronger stems and vibrant blooms, the results speak for themselves. I also appreciate how easy it is to use. Whether I'm mixing it into the soil or dissolving it in water for foliar application, it always dissolves quickly and evenly, ensuring that my plants get a consistent dose of potassium with each feeding. Overall, I couldn't be happier with Down to Earth Potassium Sulfate. It's a reliable, effective, and organic solution for boosting plant health and promoting robust growth. If you're looking to take your gardening game to the next level, I highly recommend giving this product a try. You won't be disappointed!

Wonderful Fertilizer for Berries
Down to Earth Potassium Sulfate is a great fertilizer for all kinds of fruiting plants. We grow blackberries, strawberries, and blueberries, all of which need acidic soil to take up nutrients like potassium. Potassium is required to make the fruit sweeter and larger, so this product is an ideal combination to help acidify soil and provide potassium for berris! In addition, this potassium sulfate is micronized and easily water soluble for faster results Great product and highly recommended!

Works great, just not very much per bag
Growing tomatoes in 10-gallon grow bags. Used 6 tablespoons dissolved in a gallon of water, poured half a gallon per grow bag. It's not completely water-soluble but it does homogenize nicely. My tomatoes went from producing 1 or 2 fruits here and there to producing clusters of fruits. Glad I found this stuff.

Works as expected for plants
I like using organic fertilizer but have found a local store that sells it and itโs cheaper. Like most organic fertilizers it takes time for the soil microbes to break it down, so it should be added weeks before planting.

Easy to use & potassium sulfate is superior to potassium chloride as mango trees do not like salt.
Potassium sulfate (the better choice over chloride) is supposed to help older fruit trees put out more blooms, thus more fruit. This product spreads easily along the drip line. Its success will be known if my older mango tree produces more blooms & fruit next year.
