Review: Best Stuff Ever! - I love this stuff! I have to get a bigger bag! It did wonders for everything I planted last season. I wish I could find it in a local store as I want a huge bag this year! My plants thrived with this. Germination was off the charts and growth was exponential. Everything was green and lush! I love this product!
Review: Great for Transplanting Indoor Houseplants - Purchased this on the advice of one of my plant groups. It seems to assist in the shock of transplanting and helps the roots take to the new soil.

## Questions & Answers

**Q: Is Big Foot Organic?**
A: Yes. One of the few products with actual organic certification.

**Q: Can I apply with fertilizer?**
A: Yes! It’s important to avoid high levels of synthetic phosphorus when using mycorrhizae—specifically, levels of 80 parts per million or higher. Once the mycorrhizal relationship is established, you can use any type of fertilizer without concern.

**Q: Can I use this as a top dress?**
A: No, mycorrhizal products should not be used as a top dressing unless they are in a water-soluble powder form (like Big Foot Concentrate, which is water-soluble).

**Q: Do the benefits last the plant's lifetime?**
A: Absolutely! Established plants usually need just one to two applications for mycorrhizae to develop throughout their lifespan. However, if the plant dies or if you till the soil, those mycorrhizal connections will be lost.

**Q: What types of plants benefit most from it?**
A: Nearly 85 percent of the world’s species form relationships with mycorrhizae. Big Foot Products stands out as one of the few that also offers plant growth ingredients, ensuring support whether or not your plants form mycorrhizal connections.

### ⭐⭐⭐⭐⭐ Fantastic for healthy and thriving plants
*by C***A on April 4, 2025*

I’ve been using Big Foot Mycorrhizae for a while now, and the results have been amazing! My plants are growing faster, looking greener, and producing more flowers and veggies than before. The blend of biochar, kelp, humic acid, and castings really makes a difference. It’s easy to use—just mix it into the soil or sprinkle it around the roots. I love that it’s organic and OMRI-listed, which gives me confidence that I’m using a high-quality product. The 4 oz bag may seem small, but a little goes a long way, making it a great value for the price. Definitely worth trying if you want stronger, healthier plants!
