Sul-Po-Mag 0-0-21.5 Sulfate of Potash Magnesia (K-Mag) Greenway Biotech Brand 5 Pounds

I grow lots of cukes for my Ghost Pepper pickles and this really helps them produce. Cukes have low nitrogen requirements, but they need high potassium and high phosphorus levels which this product provides. The crystals easily dissolve and are readily absorbed by the cukes. The only really downsize is the bag, it easily tears. The product is very hygroscopic and once the bag no longer seals it will turn into a brick. It's still usable but you have to break off a piece and then dissolve into water to use it.

Thank you I received it in good condition love it

I have root crops so this was essential in their development and growth! A little pricey but for me, it was worth the investment!

This is commercial grade Sul-Po-Mag. I've used it for years (though not from this vendor- only 2 bags so far from here) and it's nice to have it available since it's hard to find at any of my local garden centers. If the lower (oldest) leaves on your palm trees are yellow, orange or spotty then your trees are asking for this stuff. Same with citrus. If the leaves are turning yellow this is what they are asking for. Keep in mind that the soil needs to be warmer (late spring, summer or fall) for the plants to uptake these nutrients effectively. I will buy this again.

I have a backyard garden and I can only get 40 lbs from the Ag supplier. Smaller quantity fits my needs and I can store it easier before it becomes a rock. It is not a slow release product so I have to use small amounts every few weeks.

This is a natural source of Potassium for our garden and lawn. We are careful to use only natural and organic fertilizers and products on our property. Potassium is critical element for all life. Our soil is LIVING with nutrients and earthworms everywhere. Chemical fertilizers kill micronutrients and force the need for constant watering. We mix this Potassium with natural nitrogen and phosphorus.The mix is about 6 - 2 - 5 and makes our organic garden very healthy.

This may be a wonderful product, but they couldn't ship it to me because I live in California.

I have been using the Sul-Po-Mag annually and have found that it has improved the quality of the "soil" which it is applied to.This "soil "is primarily sand and it lacks the appropriate nutrition that the plants need. Regular fertilizers do not contain the same balance of these three essential elements. Fruit trees have been more productive and the quality of the produce has been improved.Will continue to use the product .Very pleased.
