Give your compatible plants an opportunity to develop beneficial partnerships around their roots with our granular Mycorrhizal Fungi soil inoculant. These fungi can help roots access water and nutrients already in the soil when a partnership forms. Sprinkle the granules near your plants' root zones when planting, repotting, or applying to established soil as directed.
When you're planting or repotting, placing mycorrhizal fungi near living roots can help give compatible plants a chance to form these natural partnerships. Once established, fungal networks can extend into nearby soil. Your results depend on the plant species, existing soil biology, and growing conditions.
Wondering whether your plant still needs fertilizer? Yes, when its nutrient needs aren't already met. Mycorrhizal Fungi isn't an NPK fertilizer and won't supply missing nutrients on its own. Many healthy soils already contain these fungi, so adding more doesn't guarantee an extra benefit.
Apply the granules near your plant's roots as directed on the label, whether you're transplanting or caring for an established planting. Avoid disturbing healthy roots, and keep soil conditions suitable for growth.
Why growers choose it: Mycorrhizal fungi and soil microbes, convenient granular use, and several ways to apply near your plants' roots.
