## Description

desertcart.com: Big Foot Gold Mycorrhizal Fungi 4 oz, Beneficial Bacteria for Plant Growth, Root Stimulator, Super Concentrated 3-in-1 Formula for All Plants : Patio, Lawn & Garden

Review: Quality product, possible protection of certain plants from powdry mildew! - I just want to say that I've been very happy with this product. Not long after I inoculate the yard, I get big white mushrooms growing all over the place, which is a visual confirmation. not only that, I just read a study that found that arbuscular mychorrizal fungi actually help to protect plants against powdry mildew! (I can't include the study link per desertcart rules but you can search on ScienceDirect for the study). This product contains at least TWO varieties of such! So it looks like I will be applying this more often, because powdry mildew is always a problem for certain plant species in western WA. Been using this product now for a couple of years now on an irregular basis (maybe 2x/yr).
Review: You will not be disappointed!!! - Thos stuff is incredible. My absolute no. #1 choice for a mycorrhizal supplement for my plants. My roots were going insane with my clones & seedlings

## Questions & Answers

**Q: What kind of growing medium does this work in?**
A: Suitable for All Growing Systems: Whether you're growing in soil, hydroponics, or other soilless mediums, Great White is compatible with all growing systems.

**Q: Can I use with Fertilizer?**
A: Yes! It’s important to avoid high levels of synthetic phosphorus when applying mycorrhizae at the same time—specifically, levels of 80 parts per million or higher. Once the mycorrhizal relationship is established, you can use high levels of P.

**Q: Will this last the 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: Why is the price higher than other mycorrhizal products**
A: With nearly a billion microbes, this product is the most concentrated available. You can actually use less of it, which means your cost per plant is likely much lower than our competitors.

**Q: Why do we add beneficial bacteria with mycorrhizae?**
A: Beneficial bacteria break down nutrients and minerals into smaller parts that plant roots can absorb more easily. These bacteria are an important part of the carbon and nitrogen cycles and increase nitrogen fixation in the soil

### ⭐⭐⭐⭐⭐ Great root development and plant growth after using Big Foot!
*by C***C on August 20, 2025*

Big Foot gave my plants big feet (roots)! I usually sprinkle mycorrhizal fungi on roots during a repot but recently added a little to my watering can and gave a drink to all my houseplants. It led to a plant explosion! They all have roots on roots now and tons of new leaves! (Not for vegetable plants.)
