## 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.
