Description

ARBICO Organics Root Build 240 is a micronized mycorrhizal blend suitable for most crops!

Soil preparation is imperative when readying plants and the growing environment for the upcoming season! ARBICO Organics Root Build 240 provides a mixture of mycorrhizae that aids most plants establish themselves. Mycorrhizal fungi form symbiotic relationships with plant roots to stimulate the development of healthy, strong root systems throughout the growing season.

The blend of ectomycorrhizal and endomycorrhizal fungal species in Root Build 240 is carefully mixed with other organic components and is suitable for use in a wide variety of soils and climates. The result is a replenished natural microbial system on the roots of inoculated plants that increases crop productivity, quality and sustainability.

Excellent Root Stimulator
Aug 30, 2023  |  By Janet Spaulding
I've used this product to stimulate root growth when planting in both Cape Cod and NH --particularly shrubs in late summer when prices go down and I "just had to have" a rare one that was beyond my normal price range. All of the choice trees and shrubs thrived, went through winter successfully and are in their second year. For larger trees this, plus a gator bag during summer heat caused new, costly trees to root quickly and grow under stress. I love this product.


Great product!
Mar 16, 2022  |  By Veronica
We make potting soil for houseplants and we absolutely love this mycorrhizal inoculant. Because we use it on indoor plants (and handle the soil after mixing it) we can clearly see the mycelial growth and how it adds to the soil structure. Super happy plants, too!


Great quality
Mar 6, 2021  |  By David Manning
I really like the quality of the product.


FABULOUS product!
Feb 4, 2021  |  By Veronica Oh Happy
Excellent product and extremely concentrated - it just takes a tiny bit. You'll see the colonizing mycorrhizae (white fluff), and they actively hold soil together, providing structure and filling in gaps without a loss of aeration. Makes for super healthy roots!


Plants look good!
Feb 24, 2019  |  By Richard
Used it prior to germination of several types of vegetables in preparation for spring. The seedlings are strong! Gonna switch from Plant Success to this product. Works just as well at half the price. Thanks again!
