Langbeinite 0-0-22 Fertilizer (5 lb box)

Langbeinite 0-0-22 (5 lb box) is a popular fertilizer that delivers potassium, magnesium, and sulfur all within a single particle, giving uniform nutrient distribution when spread. Its neutral pH does not alter soil acidity, and a maximum chlorine content under 3 percent minimizes the potential for fertilizer burn.

How to use

For new plantings in containers, mix 1 tablespoon per gallon of soil and blend thoroughly. Langbeinite is fully water soluble but dissolves more slowly than some potassium sources because its particles are denser, so it is not suited to irrigation systems unless finely ground.
