Unlock nitrogen naturally in the soil with Big Foot Root Boost!

Big Foot Root Boost contains Azospirillum brasilense, an all-natural and powerful nitrogen-fixing beneficial bacteria that encourages root growth in established plants, new cuttings, and seeds.  Big Foot Root Boost is 10x more concentrated than the competition allowing for more productivity.  

Azospirillum turns nitrogen into a usable form while mitigating abiotic and biotic stresses in plants.  Azospirillum synthesizes phytohormones, particularly indole-3-acetic acid, which controls adventitious root formation (root production from plant tissue).

Great for vegetables, fruits, herbs, flowers, and GIANTS. It’s safe for any rooting plant and simple enough for gardeners of all levels.  Apply directly to the soil or mix with water to make a liquid solution to build healthy, vibrant roots.

In a 2022 blinded study, 18 out of 21 professional farms preferred Big Foot Root Boost to the industry-leading azospirillum product.


For best results, apply every 2 - 3 weeks.  Directions for use are included on the bag.
