RootMax – Mycorrhizal Fungi

RootMax is a mycorrhizal fungi rooting powder designed to boost root development across a wide range of plants. The powder enhances early root establishment, enabling stronger uptake of water and nutrients. It is presented as a direct root inoculant for cuttings and established plants alike, with practical guidance for house plants and garden specimens. The formulation emphasizes vigorous growth and a faster establishment phase, particularly useful for new transplants and cuttings.
Great White Mycorrhizal Fungi

Great White Mycorrhizal Fungi focuses on rapid germination and robust rooting. It combines mycorrhizal fungi with beneficial bacteria to stimulate nutrient uptake and improve flower and fruit development. This product is positioned as a root growth accelerator, helping seeds and transplants establish quickly while supporting overall plant vigor in home gardens or greenhouse settings.
Myco Bliss Powder

Myco Bliss contains five high-performing mycorrhizal strains with a high propagule count per gram. It is designed to be applied directly to seeds or developing roots, enhancing nutrient uptake and drought resistance. This concentrated inoculant supports up to many plants per pound, making it a practical choice for large pots or garden beds where robust root networks are desired.
Mycorrhizal Fungi with Beneficial Bacteria

This product blends mycorrhizal fungi with beneficial bacteria, Trichoderma, sea kelp, molasses, and yucca to boost soil biology. It’s marketed as a root enhancer that improves nutrient uptake, supports healthier transplants, and promotes stronger plant growth. The inclusion of organic components aims to sustain soil microbial activity, aiding plants through stress and establishment phases.
4oz 4X Mycorrhizae for Plants

This ultra-concentrated mycorrhizae powder aims to maximize root development with a high spore count per gram. It’s positioned as a root fertilizer that enhances nutrient and moisture absorption, supporting a denser and more resilient root system. Suitable for transplanting, seed starting, and long-term growth cycles in containers or garden beds.
Buying Guide: Key Purchase Considerations
- Plant type and life stage: Younger plants and cuttings benefit most from active mycorrhizal inoculants, while established plants can benefit from root boosters during transplanting.
- Fungal strains and efficacy: Higher propagule counts and multi-strain blends often yield more robust root networks, but verify compatibility with your plant species and soil conditions.
- Application method: Some powders are best mixed into soil, while others are applied directly to roots or seeds. Follow label directions for optimal results.
- Soil and moisture management: Mycorrhizae thrive in properly moist, well-aerated soil. Plan watering and drainage to avoid over-saturation that could hinder fungal activity.
- Organic additives: Some products include organic ingredients (sea kelp, molasses, yucca) that support microbial life, but assess whether these align with your growing system and fertilizer plan.
- Storage and shelf life: Keep powders in a cool, dry place to maintain potency. Avoid exposure to moisture that can degrade spores and beneficial microbes.
- Label claims and certifications: Look for clear indication of multi-strain blends, propagule counts, and suitability for edible gardeners if relevant.
Overall, selecting a plant-focused antifungal and root-boosting powder should prioritize root health, nutrient access, and disease resilience. Assess your plant species, growth stage, container size, and watering regime to choose the most appropriate inoculant or powder for your garden or indoor setup.
