One 1 lb of granular can treat up to 516 small plants.

Review: I wish I could buy larger quantities here. They advertise it, but it seems only available in the USA. The combination of Mycorrhizae propagules with a small amount of Biochar, along with Worm Castings and Kelp/Humic Acid, is very effective! Un mélange parfait, qui fait effet ! J'apprécierais qu'ils nous offrent des options pour de plus gros volumes. Ce serait idéal! My Plants are addicted!
Review: 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!

## 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.

### ⭐⭐⭐⭐⭐ Review
*by P***A on 3 October 2025*

Bought the tiniest bag of these, and use them anytime I replant one of my indoor plants. As Tanner explained, there are good fungi (this) and bad fungi that will make home around your roots, so if you use this instead, it leaves no room for the bad fungi to move in and hurt the root system. It only takes a teaspoon for your little plants so even the tiny bag is going to last me awhile. It also contains worm castings which are a natural fertilizer for your plants. Nothing bad about this product! Will continue to be my go-to product from now on.
