Mykos RT4401 Mycorrhizae Granular 1-Lb | Rhizophagus intraradices

Meet Mykos RT4401 Mycorrhizae

Mykos RT4401 is a natural, organic soil amendment packaged as granular mycorrhizal fungi. It creates a living, sponge-like network in the root zone that helps plants access additional nutrients and water. By partnering with the plant’s roots, this single-species formulation focuses on Rhizophagus intraradices to support healthier underground relationships and better early growth. The result is a soil-dwelling ally that many gardeners rely on during transplanting and initial establishment, especially for tomatoes and other sun-loving crops.

Designed as a granular product in a 1-lb bag, Mykos RT4401 is easy to handle and mix into soil, mulch beds, or around planting zones. The packaging emphasizes a pure approach: this formulation contains only Rhizophagus intraradices, with no other microbes such as Trichoderma or ectomycorrhizae included. This clarity can help gardeners understand what is in the bag and how it might fit their organic gardening plan.

How it works

The fungus forms a mutual association with plant roots, extending the effective reach of the root system. This expanded network can help plants access nutrients and water more efficiently, potentially supporting steadier growth during key stages of development. Think of it as enhancing the plant’s natural root-foraging ability and giving root tips a more supportive environment to explore the surrounding soil.
