Know before you buy
Yes, this product is OMRI Listed, meaning it meets the strict standards required for use in certified organic gardening.
While it is a powerful soil amendment, it is best used as a component of a potting mix rather than a standalone medium. For container plants, blend it with your existing potting soil to boost fertility and moisture retention.
No, this compost is processed to be weed seed free, so you do not have to worry about unwanted sprouts appearing in your flower or vegetable beds.
The biochar acts as a long-term structure for the soil, while the added microbes and worm castings work to break down nutrients, making them more accessible to your plants' roots over time.
The product has a moderate, earthy odor typical of high-quality compost. While noticeable when you first open the bag, the scent dissipates quickly once it is mixed into the soil.
For lawn top dressing, apply a thin, even layer over the grass and lightly rake it in so it reaches the soil surface. This helps improve drainage and introduces beneficial nutrients to the root zone.
