0-0-20 Potassium Fertilizer 50 lb. bag

Potash, or potassium, is a macro (key) nutrient plants require. Fertilizer nutrients are represented as N-P-K on the label. Potassium promotes overall plant health, helps strengthen plants' ability to resist disease, and plays an important role in increasing crop yields, quality, and maximizing fruit size. Potassium also protects the plant when the weather is cold or dry, strengthening its root system and preventing wilt. Straight potassium is particularly beneficial to use on legumes that produce their own nitrogen or in areas where nitrogen leaching into groundwater is a concern and phosphorus levels are sufficient.
