I got this sample pack from who makes the mykos it...

Just follow the directions on the package.. Or use google to find the website of the manufacturer's recommendations. There is a pile of stuff there. I don't know if it's top dress/soil amendment or what.. And it's just a lot easier for you if you use it the way the people who made it designed it for..

Hey there! With mycorrhizae fungi your gonna want to sprinkle it on the roots of the plant or sprinkle some in the hole where you plant your seed. The purpose of the fungi is it attaches to the root system and helps absorb nutrients far better than if the plant didn't have it. It has to stay moist for it to work. Just be mindful not to overwater your plant in the mean time. I've used the same brand in the past with amazing results. Hope this helps. Happy growing!
