**Q: Do I use this product in addition to fertilizer and compost?**
A: If you have good SOIL (not dirt), which needs this fungus, you won’t need fertilizer at all.

**Q: is this Mycorrhizal Fungi 134 spores per gram ?**
A: the bag says "contains the following species of vesicular arbuscular mycorrhizal fungi: Glomus intraradices(RTI-801).....80 spores per gram)

**Q: If a plant is already established (re-potted a couple of weeks ago),  can it still be added effectively? I assume sprinkling it on top wont do much.**
A: As long as it directly applied to the root, you have accomplished your objective. That is a must! So take the plant out, moisten the root a bit so that RT4402 can stick to the root. Apply the rt4402 and sprinkle some on the bottom in the pot where the bottom of the root will be .
