Big Foot Mycorrhizae Granular | 10lb

Soil-Mix Biochar & Kelp Amendment for Multiple Beds, 10lb

Some growers want a dry soil amendment they can sprinkle or mix directly into the planting hole rather than dissolve in water first. Big Foot Mycorrhizae Granular combines biochar, worm castings, kelp, azomite, and humic acid into a dry blend that mixes easily into soil at planting or transplanting.

This 10lb size covers multiple beds or containers for growers managing several plantings at once.
