Root Drops – Liquid Rooting Hormone
Southside Plants presents a powerful dual-action rooting hormone. The formulation includes Indole-3-Butyric-Acid and essential vitamins to accelerate and optimize root growth, providing faster development and stronger roots than common gels or powders. The liquid format is versatile for water propagation, soil transplants, and specialized substrates such as leca or moss. It also aims to reduce transplant shock by supporting robust root health during early potting transitions.
Bonide Bontone II Rooting Powder
This ready-to-use powder provides a straightforward way to stimulate root development. Dip the end of a clipping into the powder and plant into moist soil to kick-start rooting. It is versatile for ornamentals, vegetables, fruit trees, and berries, and can be used with seeds or bulbs by coating them prior to planting. The product emphasizes root hormone activity to initiate root formation in both hardwood and softwood cuttings.
Mycorrhizal Fungi – Trifecta Myco Supreme
Trifecta Myco Supreme offers an ultra-concentrated mycorrhizal inoculant designed to boost root systems and soil vitality. The formula emphasizes Rhizophagus irregularis endomycorrhizae with high spore counts and bio-encapsulation to enhance survivability and effectiveness. Marketed as a natural and organic solution, it aims to improve root colonization and nutrient uptake, translating into vigorous plant performance, especially for trees, roses, and flowering plants.
Houseplant Prop Drops
This liquid prop drops formula is designed to support rapid root growth and reduce transplant shock. It is plant-friendly and easy to use for water or soil propagation, including popular houseplants like pothos and monsteras. The formulation relies on natural ingredients such as seaweed extract and humic substances, offering a gentle yet effective option for homeowners seeking a non-synthetic option.
Fertilome (10645) Root Stimulator & Plant Starter Solution
Fertilome 10645 Root Stimulator and Plant Starter provides a versatile starter solution for seeding and transplanting. The product focuses on early root formation and development, applying Indole-3-butyric acid as the active rooting hormone. It is suitable for a range of plant types including ornamentals, fruit trees, and berries, and aims to streamline the rooting process during initial growth stages.
Buying Guide
- Propagation method: Liquid formulas are versatile for water propagation and hydroponics, powders are convenient for dipping cut ends, while mycorrhizal inoculants boost soil-based rooting.
- Active ingredients: Indole-3-butyric acid (IBA) is a common rooting hormone; consider formulations with added nutrients or vitamins for enhanced growth.
- Plant type and scale: For houseplants and cuttings, gentle, non-toxic formulas are ideal; for woody plants or larger transplants, stronger inoculants may be advantageous.
- Substrate compatibility: If you use soil, peat or moss, ensure the product works well with your substrate; leca and hydroponic setups may benefit from liquid solutions.
- Ease of use: Powdered products require more handling, while liquids and pre-mixed formulas offer straightforward application.
- Safety and storage: Follow label directions; store away from children and pets; some powders should be kept dry to maintain efficacy.
- Long-term benefits: Mycorrhizal fungi can improve nutrient uptake and soil health beyond initial rooting, especially in potted plants with limited natural soil life.
- Environmental impact: Prefer products with natural or organic claims when possible, and avoid harsh synthetic additives for indoor air quality.
