Perfect solution if you have limited space to work and still want a lot of soil
While this wasn’t my first experience working with plants, it was my first time needing to completely replace soil to rescue a plant from gnat-infested soil. I chose Back to the Roots Organic Coir, 51 Quart Expanding Soil because I wanted a clean, organic option that would help eliminate pests rather than reintroduce them. I also was working with a small space to replant. I did this in the bathroom. I placed the compressed block directly into a 27-gallon tote and added water let it expand and did a little chopping with a spatula. What stood out the most was just how much soil this product produced. Expanding the coir directly in the 27-gallon tote nearly filled the entire container, which really exceeded my expectations for a single compressed block. The soil has a rich, fine texture and looks evenly hydrated and well-aerated, as shown in the image. It was easy to work with and didn’t feel heavy or muddy, making it ideal for gently replanting without compacting the roots too tightly. Overall, this expanding soil made a stressful plant-rescue situation feel manageable and successful. The lightweight texture retains moisture while still draining well, which is especially important when dealing with fungus gnats. Since switching to this soil, the plant feels more stable and supported, and the surface stays clean instead of soggy. For anyone needing to refresh contaminated soil, repot stressed plants, or simply wants a clean and reliable organic growing medium, Back to the Roots Organic Coir delivers excellent volume, quality, and peace of mind. Picture is of the newly repotted plant.

THE BEST YOU WILL EVER BUY
Back to the roots is the best soul I have found yet and I have tried many. My plants never get overwatered in this sore for the drainage that it gives to my plants they never get overwatered again. I mix Burprer bone meal into it and it is also the best. I do a lot of cuttings off my coleus plants and never had roots grow so strong and beautifully. Between the perfect soil and the perfect fertilizer for my plants they are blooming so beautifully and fast. Never had this happen before my roots has never been so healthy my plants is never been so healthy it has been since I have switched to these two things. Very pleased I am and I am thinking about raising my flower bed with this soil but then they will never get overwatered either. You are not go wrong by using the soul or using the fertilizer I have said connect beautifully together. Wish I could give you a 10 star but there is only five but I still give you a 10.. Thank you for the best soil that makes my plants grow strong and beautiful.

Great Ingredient for DIY Soil Mixture
I’m always in search of the perfect soil blend that supports seed germination, seedlings, mature plants, and indoor and outdoor vegetables. The Back to the Roots expanding soil has become a key ingredient in my DIY mix. The directions suggest adding 7-10 gallons of water, but I use about half that. I place the 12x12x4 brick in a 21-gallon bucket and follow this process: • Pour on 2 quarts of water • Let it expand • Scrape off the slightly moistened soil • Sift • Repeat until the entire brick is sifted This method avoids over-saturating the soil, separates out fibrous coconut husk, and leaves behind rich, airy, fluffy soil. The sifted fiber is debris-free and works beautifully as top dressing mulch. I’ve noticed slightly lower germination rates when using pure coco coir, and some seedlings tend to die off around the 3” mark. To improve results, I mix my sifted coir with vermiculite, perlite, and a bit of horse manure. One of the photos show the original brick material, sifted soil, and fibrous husk - all from the same process. The other photo shows the soil blend in use, in a batch prepared from an earlier coco brick using my sift/blend method. The video clip captures the sifted soil texture as it sprinkles from my hand into the bucket. I appreciate that this product is odor-free, 100% organic, and upcycled. My plants respond well to it, and it’s become a reliable part of my soil-building process.

Good Quality Potting Mix, But Be Mindful of Mushrooms
recently purchased this potting mix, and overall, I’m quite satisfied. The soil feels light, airy, and well-draining, which made planting very easy. My plants seem to be thriving so far, and the mix retains moisture without feeling too soggy. However, about a week after planting, I noticed some small mushrooms popping up in the pot. While it initially worried me, I learned that this is common with organic-rich soil mixes. The mushrooms are harmless and indicate the presence of healthy microorganisms. I just removed them and adjusted my watering routine to avoid overwatering. Pros: • Light, airy texture • Holds moisture well without becoming compact • Perfect for indoor and outdoor plants Cons: • Mushrooms may appear due to the organic material • Requires careful moisture management to avoid fungal growth

Excellent value for home worm bins
Works great in worm bins. I have been using a saw to break the brick down into smaller bricks and putting those cut down bricks in the bins but over the moisture barrier. It stays compact enough. Keeping it in the moist bin when I am ready to use it I can easily break off a hand full and and hand pulverize it. I have had no issues with moisture retention or excessive moisture. It helped me create a very stable bin. The value for my worm bin set up is excellent it has given me about a year before I needed to reorder. I personally would not use it as a soil but I would use it as an amendment. Having the excellent moisture retention it would help create an excellent potting soil mix. There is no dirt or soil it seems to be ph neutral. So definitely worth the reasonably low price.
