A peat-free organic soil conditioner and amendment

A revolutionary organic soil conditioner and amendment made from upcycled, organic paper fibers. Prime is OMRI listed for organic growing and is the best soil for sustainably minded, and organic gardeners. This growing media is lightweight, and significantly less dusty than traditional soil mediums. Prime is also the cleanest, most consistent soil on the market, with no pathogens, weed seeds or other heavy metals and harmful ingredients and every batch is tested to ensure quality and optimal performance. PittMoss Prime is a soilless growing substrate that also requires significantly less water and applied fertilizer because of its ability to retain and better manage applied resources, evenly distributing them throughout the porous particles to be more available to the plant’s roots. PittMoss Prime is the best soil conditioner with high amounts of readily available carbon, perfect for creating a living soil environment that is chalk-full of soil biology! Prime is a wonderful and eco-friendly soil amendment that replaces sphagnum peat moss, perlite and vermiculite for gardeners looking to blend their own mix, or to improve soil conditions. PittMoss Prime is a great option for improving and establishing lawns, planting trees and shrubs, and replacing peat in potting soil blends. When used as a peat substitute for potting soils, PittMoss recommends using at least 30% – 50% Prime with a blend of compost and other amendments.

How it’s Made: Prime is made from PittMoss’s proprietary and revolutionary recycled paper fiber. PittMoss engineers this fiber to have incredible properties that allows plants to grow big and strong, even under stressful conditions. This revolutionary product is the most sustainable and high-performing growing media on the market made 100% in the United Sates. PittMoss sources all paper ingredients from local recycling facilities and hand sorts each batch to ensure zero contaminants. Each batch is hand sorted and processed in Ambridge, PA using PittMoss’s custom and patent-pending machinery. PittMoss conducts extensive testing on each batch, and proudly shares information on heavy metals and more with the public via our blog and published research, and as requested.

Ingredients: 99.9% PittMoss paper fibers, with small amounts of organic bark.

    Seems to be adequate

    This is the 2nd bag I have bought. While it is still very early to determine how effective the product is, I generally believe it is good to use. I have planted a lot of shrubs this year, so I have been putting one or two handfuls in the bottom of the hole, along with handfuls of alfalfa pellets. There are no bad effects so far, but it is hard to tell if the product is effective.

    It’s working great so far, when are you going to start selling it in Utah? $40 dollars every time I buy a bag!

    Great product

    I have purchased many, many bags of this product and think it is terrific. I mix it with compost to make a wonderful potting soil, and soil for potting perennials that I have divided. I also mix it with coconut coir for mulch. Rarely, if ever disappointed. Hopefully, in the future the company can figure out a way to dehydrate and compress the product to reduce the plastic packaging, thereby being even more environmentally forward than they already are.

    Good amendment

    This is my second purchase. Generally a good product, but it’s efficacy depends on it’s performance over time. Ask me next year.
