To the spider person… that is TOTAL AND COMPLETE BS and you know I’m right. If a never before seen spider sprung from the bag .. 1. You would have taken a pic of that was true 2. If there was a spider on the bag you must have left it open and it crawled into the bag from YOUR HOUSE! Y’all are funny… the product is great!

## 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.

### ⭐⭐⭐⭐⭐ WHOA Plants are loving this...
*by M***W on May 19, 2025*

I purchased on the advice of a local plant specialist, and my plants are growing like crazy! I live in North Texas and lost a couple of favorites during the winter freeze (pictures), and this revived them!! I cut them back to nubs, loosened the dirt, and poured this around the roots. Now all my indoor and remaining outdoor plants have been repotted with fresh potting soil mixture with this product. A little goes a long way, and now that everything is planted, I give a sip before watering. Leaves and blooms galore.
