150g RHS Empathy Rootgrow
The first and currently the only plant or soil treatment to be licensed by The Royal Horticultural Society. RHS gardeners find plants treated with Rootgrow have superior plant establishment with better natural vigour. Mycorrhizal fungi do everything plant roots do, but better. When new plants are planted with Rootgrow it takes only 2-4 weeks under normal conditions for these fungi to start benefiting plants. In that time they attach themselves to the plant's root system and grow out rapidly into the soil, searching for nutrients and water. They essentially become part of the plant's own root system.
