Can I use this product on my established plants?
Yes! one of the few water soluble products on the market.
Can I use as a top dress?
Yes, just mix big foot powder with water and apply around the root zone of the plant or tree.
Will this last for entire life of the plant?
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.
Does my plant form with mycorrhizae?
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.
Can I apply with fertilizer?
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.

Best product ever!
This product from Big Foot is AMAZING!!!! My plants are thriving and loving it! Sorry but I have to call out a couple of negative reviews about this product… 1. To the woman who’s hand get dirty when she reaches into the bag to get the scoop… two words WEAR GLOVES!! Dealing with plants is far from a day at the spa, maybe you shouldn’t own plants.2. 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! Don’t try to damage a company’s rep that is actually producing a great product!

WHOA Plants are loving this…
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.

No placebo affect, it really works!
I’ll make this simple and concise.. the water solubility is immaculate.. it turns pitch black, pretty cool.. I used Big Foot only upon transplanting 11 plants 2.5 weeks ago, currently there are thick white roots coming out of the bottoms of my pots and my cloned plants look happy.. as far as for my older more developed plants, they appear to be taking more nutrients from the soil.. I normally use Great White but depending upon this harvest, I might make a permanent switch..

Honest Review PRO –
Hydroponic Use friendly.
Received early today and immediately mixed up and gave to some plants a 4-5 weeks in Veg. I use General hydroponics rapidstart as well but in my research I felt this had better reviews then competitors “great white” and believe the quality is higher.I am using in DWC with air stones. This stuff is super fine, like dusty powder really. So if used with soil I certainly believe it would easy be watered in.For hydroponic use time will tell if it helps my case, but rest assured this will NOT clog a sump. Oh and when mixed with water it is DARK BLACK!Comes with ml scooper which doesn’t make sense as the bag states tsp? Weird… but I bought for product. Package comes with a clearly marked expiration date approx 2 years out.*** so it’s been a few months. This stuff absolutely works I have started plants from wild flowers, lettuce and produce types, hemp types, the growth when added at the begin is noticeably different as I did a side by side with lettuce for 3 weeks from germination. Like I said before it’s dusty and will turn the roots darker as they catch the particles but not slimy roots as that’s root rot. Cant go wrong with purchase and being too little or too heavy on the mix will NOT hurt the parts regardless of stage.

My plants love it.
My plants love this stuff. It is a bit messy but you only need to use it once a month or so. I haven’t had a problem with root rot since I started using it. My plants seem stronger and look great.

Seems to be helping my plants… they were pretty lackluster before and now they seem to have more growth. Compared to other fertilizers ive use this one seems pretty gentle and doesn’t harm my plant. Other ones have caused my plants to turn yellow
