Conditions and Improves Soil Naturally - Greensand is an all natural sandstone product that is formed from ancient mineral deposits. Used for centuries for both its improvement of soils and its increases in productivity when used in fields and gardens. Along with its mineral content, greensand can also increase moisture holding capacity in soils.

Greensand is a natural mineral harvested from ancient ocean floors. As the seas receded, they left behind nutrient-rich marine beds (these deposits harden into layers of minerals) where rich sediment is harvested from the sandy rock for garden soil amendment. Greensand fertilizer is a rich source of glauconite, which is high in iron, potassium, and magnesium. All these components are important to good plant health. It also helps loosen soil, improve moisture retention, soften hard water, and increase root growth. Greensand soil supplement has been marketed for over 100 years but has actually been used for centuries.

Greensand is recommended as a soil additive for indoor / outdoor container gardening, raised bed gardening, grow bag gardening, and traditional farm and field use. Watch your plants thrive when you choose Soil Sunrise for all your gardening needs!

TIPS:
If you're not sure how much to add, applying the larger amount is a safe bet because greensand cannot burn your plants or over-fertilize.

Thank you to the Soil Sunrise Store for offering Greensand here on Amazon as I was unable to find it locally this year. I notice that this Soil Sunrise product was blended in KentuckyGardeners often use greensand to amend soil when it could benefit from Manganese. Personally, I use it in my own blend of seedling mix. Also, I add a bit to the planting spot for my tomatoes, which love it, and I find that it intensifies their flavor. Greensand is a slow-release fertilizer. It helps the soil store calcium, potassium and the manganese which will be of benefit throughout the plants life. A little goes a long way. I add greensand 1 cup at a time; but, I’m mixing roughly 4-5 cubic feet of seed starter mix in a wheelbarrow. If I were doing small batch potting or garden planting, I’d figure 2 tablespoons to a roughly a gallon of potting mix.Tip: Consider setting your bag of Sun Soil Greensand into a gallon size zip bag BEFORE opening the greensand. The product bag is difficult to re-zip and the greensand is very powdery. You don’t want to lose any precious bit of this garden magic.

Most people, including me have never heard of greensand much less know what it does.

Most people, including me have never heard of greensand much less know what it does.I’ve this last summer, I started the process of doing everything organic and natural, including fertilizers (of which many are man made and will lower populations of “natures good guys.)”As the end of the season came around, I realized despite all the organic forms of fertilizer I bought and applied, I had not applied very much if any “K” in the “N-P-K” ratio (N-Nitrogen, P-Phosphorous, and K-Potassium). This occurred to me as my tomatoes and other veggies started flowering/fruiting, knowing the Potassium is essential in this last phase, as well as serving many other essential plant processes.So I went looking for organic single ingredient fertilizers high in potassium and found very few candidates. Which was a surprise considering how many of the same type of products available containing high amounts of nitrogen, or phosphorus.One of those products was greensand which is derived from ancient marine mineral beds which spoke to its high quality. It’s known to slowly release nutrients (potassium, calcium, magnesium, and other micronutrients) into the soil. This worried me since I applied it so late in the season, but I was shocked at how well it worked! 7/8 of my 4-5 foot tall tomato plants had been infested with several pests and accompanying issues, which equated to brown dried out leaves with no green from the ground up to about 4 feet. I applied this as a last ditch effort to get at least a tomato or two and was shocked at the results!The plants started growing healthy, green leaves and branches above the completely desolate 4 feet of stem and was actually growing blooms and tomatoes. It was like they were freshly planted, without a pest in site, all within about 2 1/2 weeks from adding this product into the top couple inches of soil and watering in. Would totally spread the word about this amazing product!
