Mycorrhizal Fungi Organic Root Enhancer
This Smart Grower product features a 5-strain blend of mycorrhizala fungi designed to support diverse root networks. Each bag aims to deliver fresh, potent organisms to boost nutrient and water uptake, promoting healthier growth for gardens, lawns, and houseplants. The formulation emphasizes compatibility with common fertilizers and compost teas, making it a versatile option for multiple growing environments.
Root Drops – Liquid Rooting Hormone
This product combines a rooting hormone with a proprietary vitamin mix to accelerate root growth and reduce transplant shock. Its liquid, dropper-friendly format simplifies even distribution across water propagation, soil transplants, and specialized substrates like leca or sphagnum moss. It’s designed to support rapid root establishment and robust early growth in a variety of indoor and outdoor settings.
TPS NUTRIENTS Billions Concentrated Microbial Root Enhancer
TPS NUTRIENTS offers a highly concentrated formula with over a billion CFUs per gram, including five bacterial strains, four mycorrhizae strains, and one Trichoderma strain.

Bonide Bontone II Rooting Powder
Bonide’s Bontone II is a ready-to-use rooting powder designed to promote quick root development when dipping cuttings before planting. While highly effective for cuttings, it’s also applicable to seeds or bulbs by coating them in the powder and storing in a bag for later use. The product acts as a growth stimulant to support root formation in a range of ornamentals and edible varieties.
True Organic Root Enhancer
True Organic Root Enhancer emphasizes natural mycorrhizal fungi to promote vigorous root development and resilience against stress. It is positioned as a seedling-friendly option that helps establish a beneficial root-soil relationship early in a plant’s life, supporting improved nutrient and water uptake across vegetables, fruits, and flowers.
Buying Guide: Root Enhancers For Different Scenarios
- Microbial diversity vs. single-strain products: Multi-strain blends may offer broader root colonization and resilience, especially for mixed plantings, while single-strain formulas can be sufficient for specific crops.
- Form factor and application method: Liquid hormones are convenient for propagation and quick treatment, while powders and granules are durable for cuttings and soil incorporation. Consider your medium (soil, coco, hydro) and irrigation setup when choosing.
- CFU counts and viability: Higher CFU counts can indicate stronger microbial presence, but freshness and storage affect performance. Look for products that advertise live, viable organisms and clear handling guidance.
- Compatibility with fertilizers and substrates: Some products are designed to be compatible with compost teas or standard fertilizers, while others may have tighter compatibility guidelines. Always verify compatibility with your feeding regimen.
- Plant stage and goals: Seedlings and cuttings often benefit from root stimulators or mycorrhizal fungi to establish roots, whereas established transplants may require stress-reducing solutions to ease adaptation to new pots or soil.
- Safety and sustainability: Opt for products with natural ingredients or beneficial microbes sourced with minimal harsh additives. Consider organic or garden-grade options if you prioritize sustainability.
