    Grandular Potassium Sulfate

    Posted by Bruce Saunders on 18th Feb 2020

    Potassium Sulfate is what it is - Potassium Sulfate. I personally like the granular version as it is a slower release of the material which is a big benefit in Florida's very sandy soils. It's also a big bonus that this product is an OMRI listed product which I prefer to use whenever possible. The product is packaged well by the manufacture with sturdy waterproof bags. My highest review in my purchase goes to Seven Springs Farm Organic Farming & Gardening Supplies LLC. The ordering process was easy; the customer service is fantastic; the order came in promptly; and, the company boxing of each 50 lbs. bag was excellent leading to no issues with shipping. If I had one complaint it would be that Seven Springs Farm Organic Farming & Gardening Supplies LLC is not in my hometown area which would help in shipping cost. Seven Springs Farm Organic Farming & Gardening Supplies LLC is an awesome company to work with -- thanks for your service and attention to detail. I'll be back in the future - keep up the awesome work.
