Rootgrow fungi are so effective that they are "as good as essential" for planting perennial trees and shrubs, and bulbs, especially on poor or depleted soils.

It didn't attain widespread garden use until the 1990's, but now everyone understands that boosting mycorrhizal fungi at planting time is extremely effective.

They form a protective, symbiotic sheath over a plant's delicate feeding roots, which massively increases the availability of many soil nutrients.
You can think of them as a "third party stomach" for roots.

Every packet of Rootgrow comes with dosage instructions.
