Granular mycorrhizae: These are granules or powders that you apply directly to the soil or the plant’s root system. They can also be mixed with seeds by placing them inside a seed packet.
Soluble mycorrhizae: This is a premixed liquid that you apply to root balls or the soil. Use this to drench the soil or to water established plants. Always be sure you reach deep into the plant’s root system when applying these fungi. They should be applied to damp soil covered with mulch. Sunlight prevents the growth of mycorrhizae.
