Great fertilizer
This is the third year that I've used this product. It's a good way to get potassium into depleted soil.

A GAME CHANGER that has given me more fruit than I know what to do with!
The main reason that I purchased this was because I heard it was excellent for stimulating the growth of bananas on my trees. I have had banana trees for three years, watering frequently, and even using 10-10-10 fertilizer, but with no success in growing bananas. So I decided to give us a shot, hoping for at least a nice thick bunch of bananas. Much to my surprise, a nice bunch grew on both of my trees. Over the months, I watered the trees and continued to add this potassium-rich Langbeinite to ensure that the bananas grew thick and hardy. Much to my amazement, three more bunches of bananas grew on adjacent trees and now I have more than I know what to do with! Not only is this outstanding to stimulate fruit production on banana trees and various other fruit trees that I have in my yard, but I use this on my palm trees and the fronds are thick, beautiful, and luscious.

Got fabulous results...it is worth a try
Well, I didn't expect to get the stunning crops from my apples, figs and persimmon espaliers - that are literally crammed into a 400 sq' allotment garden - but I did. The only thing I changed from the low nitrogen 5 3 1 GroPower regimen I've always used was adding Langbeinite by the handful three times throughout the dormant and leafing season. It would be pretty expensive to use on my small citrus grove but I suspect those trees, also planted pretty close, would benefit, too. The results were slow to show but this product made my sad, sad roses look like champs, my struggling newer espaliers produce wonderful fruit, and my established apple espaliers had amazing crops in both size of fruit and quantity and I was blown away. I have to say that an associate at an Armstrong Garden Center suggested it and I was skeptical and then I figured I had nothing to lose.

Has MG and S needed for blueberries.
Has plastic bag to hold langbeinite so it stays dry and doesn't clump.

Great Product, Damaged in shipping
This garden soil supplement is amazing, long lasting mineral support for your garden veggies. The packaging is in thick plastic, but the bags are shipped in thin Fed Ex padded envelopes that puncture and tear the bags. Of the 8 bags we ordered, 2 were damaged in shipping. It’s still a good deal at this price for the larger amounts of the product. I’d recommend sliding some cardboard into the Fed Ex envelopes to protect the Langeinite Bags in shipping.
