## Overview

Xtreme Gardening Mykos is a 2.2 lb organic mycorrhizal fungi root stimulator that naturally expands root systems, enhancing water and nutrient uptake. OMRI listed and chemical-free, it supports faster growth, higher yields, and improved transplant success across vegetables, flowers, and trees.

## Description

Mykos is a fast-growing, beneficial fungi that connects many of the eneficial microbes in the soil to host plants. This "symbiotic" relationship inceases the supply of nutrients to plants, increasing the availability of both moisture and most of the fundamental elements required for plant growth. This greater nutrient availability leads to a bounty of healthier bigger plants and "Bumper Crops" Mykos has been used to produce world record-breaking pumpkins every year since 2006.

Review: The BEST! - I don't know what this stuff is exactly - or how it works - but it's the best thing I've ever done for my plants! The difference in growth is insane! Before, when I'd transplant anything, there was a 50/50 chance it was a gonner due to transplant shock, etc. Now? I have a 99% success rate every time as long as I use this! I use it in EVERYTHING now! I even made a liquid out of it to water my plants (as an experiment) and it worked great! Hands down, best planty item I've purchased. I'd give it 10 stars if I could!

## Questions & Answers

**Q: How many endomycorrhizae and ectomycorrhizae species are in this?**
A: Endomycorrhizae: Glomus Intraradices 80 spores/cc. Just one strain. No ectomycorrhizae.

**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 .
