Sulfate of Potash 0-0-50 Granular Fertilizer
Southern AG Sulfate of Potash 0-0-50 Granular Fertilizer is a concentrated potassium fertilizer designed to help correct potassium deficiencies in low-potassium soils. With a 0-0-50 fertilizer analysis, it delivers soluble potash without adding nitrogen or phosphate, making it a targeted solution when plants need potassium support for stronger roots, sturdier stems, healthier tubers, and improved overall plant vigor. The product contains granular potassium sulfate and is intended for soil application, not spray use.
This granular potash fertilizer is suitable for vegetables, flowers, shrubs, and lawns. It may also be used to help address potassium deficiency in plants such as avocado, beans, corn, cherries, citrus, grapes, palms, and roses. Potassium plays an important role in root growth, water regulation, photosynthesis, plant strength, winter hardiness, and disease resistance.

Application Instructions
Spread the granules evenly over the intended treatment area, keeping the product on the lawn or garden soil. After application, water thoroughly to help move the nutrients into the root zone. Avoid applying near water, storm drains, or drainage ditches, and do not apply when heavy rain is expected. Sweep any granules that land on sidewalks, driveways, or streets back onto the lawn or garden area.
