This is important - I think - because I don't always have the time or energy to repot my plants. So, maintaining soil health is important. I also use quality organic fertilizer and a product which neutralizes tap water chloramines, so I can't be completely sure, on balance, what's doing what to keep my plants healthy and happy, but the combination works really well. There's a lot of product in the bag, and will easily nourish a lot of soil. I have above 50 plants and have already gone through a couple of cycles with Big Foot with plenty remaining. Because it contains organic ingredients including macrobiotics and those are living organisms, I'll assume that this product doesn't have an indefinite shelf life, however, and whatever I don't use within a year, I'll likely use somewhere else, maybe outside on the trees and shrubs. Overall, seems to me to be a brilliant addition to my plant care regimen, because as I like to say, if they're happy - I'm happy. ### ⭐⭐⭐⭐⭐ Great boost for my plants! *by on Reviewed in the United States May 25, 2026* I used Big Foot Mycorrhizae for my potted plants and garden plants, and I really like it so far. It’s easy to apply when repotting or refreshing soil, and I feel like it helps support stronger roots and healthier growth. I like using it especially for plants that need a little extra help adjusting after being moved or repotted. A great product to keep on hand for plant care. ### ⭐⭐⭐⭐⭐ My roots hired a support team *by on Reviewed in the United States June 7, 2026* Picked this up because it’s one of the few mycorrhizae products I found that can be added directly into your watering routine instead of only mixing it into soil during repots. Super easy to use and a little goes a long way.Could absolutely be placebo plant-parent delusion, but I genuinely feel like I’ve noticed less transplant shock and healthier root systems since adding it into the routine. A couple plants that usually throw a dramatic tantrum after repotting barely skipped a beat. I also feel like it’s helped keep any sketchy root rot issues from snowballing, especially in denser mixes.At minimum my plants seem happier. At maximum I may now believe in beneficial fungi propaganda. ## Frequently Bought Together - Big Foot Mycorrhizae Water Soluble Concentrate for New and EXISTING Plants - Includes Worm Castings, Kelp, Azomite, Biochar, Humic Acid - 4 Ounces - Big Foot Mycorrhizae - Double Your Plant Size – Easy to Use – Made in USA – Treats 30 Plants (7,500 mycorrhizal Spores) - Big Foot Probiotic Root Boost Water Soluble Powder for Established Plants and Transplants - Grow Root Size, Increase Nitrogen, Grow New Plants from Cuttings, Pea Inoculant - 5 Ounces --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.us/products/115988918-big-foot-water-soluble-mycorrhizae-rooting-powder-organic-plant-food](https://www.desertcart.us/products/115988918-big-foot-water-soluble-mycorrhizae-rooting-powder-organic-plant-food) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-08-10*
