Organic Langbeinite 0-0-22 Sul-Po-Mag 4LB - Made in USA Soil Amendment for Indoor/Outdoor Plants & Flower Gardens. Water Soluble Potassium/Magnesium/Sulfur. Low Chlorine Fertilizer. OMRI Listed

Good product

Really helped get the middle and late blooms established . Well worth the money. Mixing takes longer than other water-soluble fertilizers.

I get good results. This is part of my regimen. I add at transplant with other nutes.

Great flavor booster on my girls

Great results last season, and current crop is looking good. This brand is a better value than the one I bought before. The fact that it's water soluble make it easy to apply, and organic means you won't burn your plants and you don't need to flush them before harvest.

The product got moisture in the bag and was clumpy instead of a powder making it difficult to apply. It clumps up into hard balls being laborious to break up. The “powder” works as it should.

Based on a soil analysis, we needed this magnesium product to amend our garden soil. Magnesium wasn’t easy to find this spring, so thank you Amazon for carrying this product.

I've used several fertilizers and soil amendments from CZ Garden Supply - I've been super happy with every product I've tried and the Langbeinite 0-0-22 Sul-Po-Mag is no exception. I really love that CZGS products are made in the USA.This potash fertilizer is a finely milled powder - it is very evenly ground with no clumps. I add mine directly to the soil or side dress my plants, but after reading another review about using this to mix up a foliar spray, I think I may give that a try this year. I love CZGS offers mono-supplements so you can custom fertilize your plants according to your needs.These bags are resealable and the bags do not degrade - I've been bad and left my older bags outside where they get exposed to the elements and had no issues with the bags failing or the contents getting wet.Awesome plant supplement. I'll definitely continue to buy from CZ Garden Supply.
