Can’t be easier to use an your places will love it
I’m very happy with this mycorrhiza an it was shipped fast. Just sprinkle it on your roots when you transplant or first plant an your good to go. Explosive growth coming up lol. I’ve used other mycorrhiza an have had good luck but the growth I noticed after applying the myco giant was hands down better then any others.
