What is Mycorrhizal Fungi good for?
Allgood Farm Mycorrhizal Fungi Root Booster is a natural root enhancer which stimulates plants and trees to grow a strong secondary root system.
Mycorrhizae are beneficial fungi which live symbiotically attached to the roots of plants, helping them to absorb water and nutrients more efficiently.
By stimulating plants to grow an extra secondary root system, the mycorrhizae boost healthy growth and increase drought resilience.
Allgood Farm Mycorrhizal Fungi contains both Endomycorrhizae and Ectomycorrhizae, making it suitable for most herbaceous plants, including vegetables, houseplants, and fruiting plants, as well as woody trees and shrubs, such as pines, oaks, and birches.
Our mycorrhizae are mixed in with zeolite powder which improves their spreadability, and helps them stick to roots more efficiently.
Promotes secondary root development, improving nutrient uptake and drought resilience.
