A one-time inoculation of plants can establish the mycorrhizal fungi in the soil where they both attach to the new roots and also multiply in the soil. Apply as drench immediately after laying sod, seeding, or transplanting flowers into beds. The beneficial fungi will attach to the roots of both established trees and plants, plus help new sprouts get started and develop in poor soil conditions. A one-time application to bare root plants helps them establish themselves in any soil. RD is a water absorbing horticultural hydrogel of mycorrhizal inoculant that mixes instantly with water to make a convenient slurry that clings to bare roots.
Total coating insures better final contact with roots after planting.
Each jar of inoculant makes at least 10 gallons of slurry. No need to coat all roots of larger transplants. No harm in applying slurry at heavier rates. For maximum benefits, the use of lower analysis gradual-release fertilizers is recommended. Insecticides and herbicides that do not kill the host plant are generally not harmful.
