What this inoculant does

Xtreme Gardening Mykos is a granular mycorrhizal inoculant for the root zone. The label identifies the species as Rhizophagus intraradices and directs gardeners to place it around roots or in the planting hole.

That makes the product easy to place in the workflow. It belongs at the moment when roots are visible and the plant is ready to settle into fresh soil.

How it fits into garden work

Mykos suits transplanting vegetables, fruits, herbs, and flowers into containers, raised beds, and in-ground spaces. It can be used when a gardener is moving seedlings up, setting nursery starts, or planting into a prepared bed.

The rhythm is straightforward: open the hole, add the inoculant where roots will touch it, set the plant, backfill, and water.

What the package feels like to use

The granular texture makes sense near a potting bench or transplant station. A clean spoon or scoop helps with small amounts, especially around plugs, cell trays, and young starts.

This is a focused root product. It does its work by being placed in the right spot at the right stage.
