Review: Miracle! - Incredible product! When I planted my current run of 9 plants, I decided to give Bigfoot mycorrhizae a shot. I've used a couple other brands before. I used once a week, in a gallon of water. At week 3 I COULDN'T BELIEVE how the roots were! I grow in coco. The roots took up the entire buckets, plus roots out the bottom! I've never seen anything like it. Got a ton of goodies: Humic, Myco Biochar Worm castings My plants go nuts for it!
Review: Great boost for my plants! - 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.

## Questions & Answers

**Q: Can I use this product on my established plants?**
A: Yes! one of the few water soluble products on the market.

**Q: Can I use as a top dress?**
A: Yes, just mix big foot powder with water and apply around the root zone of the plant or tree.

**Q: Will this last for entire life of the plant?**
A: Yes, established plants typically require just one to two applications for mycorrhizae to develop throughout their lifespan. However, if the plant dies or if you till the soil, the mycorrhizal connections will be lost.

**Q: Does my plant form with mycorrhizae?**
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.

**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 high levels of phosphorus.
