Seems to work well with roses
Never used this stuff before - never even heard of Mycorrhizae. Someone recommended it, done bought some and followed the directions on the bag. I planted five dormant, bare-root “big box store” roses in the spring. Didn’t expect much from $9.95 roses (the local nursery had some for $25+ each - they must be special!) and I was just filling a space in the yard. However, all five are thriving.Several articles I read from rose experts said not to expect much the first year, but my roses are beautiful and blooming! I’d definitely use this stuff again - thinking about added some more “budget” roses next spring. 😁

Great product, great price
I ordered this product July 29th, 2026, and I applied it to all my plants on August 3rd, it’s august 10th today and my plants are thriving and doing extremely well.I recommend Bigfoot mycorrhizae over more expensive alternatives mykos, great white, and dynomyco. It provides great benefits without increasing your cost per grow too much.

Tanner the Planter Recommended
Bought the tiniest bag of these, and use them anytime I replant one of my indoor plants. As Tanner explained, there are good fungi (this) and bad fungi that will make home around your roots, so if you use this instead, it leaves no room for the bad fungi to move in and hurt the root system. It only takes a teaspoon for your little plants so even the tiny bag is going to last me awhile. It also contains worm castings which are a natural fertilizer for your plants. Nothing bad about this product! Will continue to be my go-to product from now on.
