Symbio MycoGro Organic Starter Fertiliser

MycoGro Organic Starter Fertiliser is a premium, slow-release plant feed enriched with mycorrhizal fungi and beneficial soil microorganisms. Specially formulated for new lawns, trees, shrubs, vegetables, and flowers, it supports strong root development, enhanced nutrient uptake, and long-lasting plant growth.

This organic fertiliser is ideal for inert growing media, fallow soil, or after a winter period when soil is depleted. Its balanced NPK 5.3.8 formulation provides steady growth without a sudden “green flush,” making it perfect as a starter feed for newly sown lawns, a summer feed for established lawns, or an initial nutrient boost for new plants.

The included mycorrhizal fungi form symbiotic relationships with plant roots, extending root systems, increasing stress tolerance, improving soil structure, and boosting yields. When applied to new lawns, mycorrhizae can halve the establishment period, helping your grass thrive faster while using fewer inputs.

Suitable for professional landscapers, gardeners, local authorities, schools, and home gardeners, MycoGro Organic Starter Fertiliser is an easy-to-use solution for promoting healthy, sustainable plant growth across all garden and landscape projects.
