How Fast does it work?

The mycorrhizae go to work immediately after application to a growing plant root and will take about four weeks to establish the symbiotic relationship. Though it varies by plant species, growing protocol, etc., it generally takes about eight weeks for benefits to become visible to the grower in comparison trials. Differences may be visible sooner in more stressful growing conditions, as the mycorrhizae can benefit the plants most.
