Can I use this product on my established plants?

Yes! one of the few water soluble products on the market.

Can I use as a top dress?

Yes, just mix big foot powder with water and apply around the root zone of the plant or tree.

Will this last for entire life of the plant?

Yes, established plants typically require just one to two applications for mycorrhizae to develop throughout their lifespan. However, if the plant dies or if you till the soil, the mycorrhizal connections will be lost.

Does my plant form with mycorrhizae?

Nearly 85 percent of the world’s species form relationships with mycorrhizae. Big Foot Products stands out as one of the few that also offers plant growth ingredients, ensuring support whether or not your plants form mycorrhizal connections.

Can I apply with fertilizer?

Yes! It’s important to avoid high levels of synthetic phosphorus when using mycorrhizae—specifically, levels of 80 parts per million or higher. Once the mycorrhizal relationship is established, you can use high levels of phosphorus.
