Garden Safe Brand TakeRoot Rooting Hormone
The Garden Safe TakeRoot powder-based rooting hormone promotes new plant growth from cuttings. Its active ingredient, indole-3-butyric acid (IBA), mirrors naturally occurring plant hormones to encourage root initiation. Application involves moistening the cutting end, dipping it into the powder, tapping off excess, and planting. Suitable for a wide range of home, garden, and greenhouse varieties, this product supports efficient propagation with a straightforward dipping process.
Bonide Bontone II Rooting Powder
Bonide Bontone II is a ready-to-use rooting powder designed to accelerate root development from cuttings. To use, dip the clipping tip into the powder and place in moist soil to support the rooting process. It’s marketed for multiple uses, including seeds and bulbs when coated in powder, and supports root production in both hardwood and softwood cuttings across ornamentals, vegetables, fruit trees, and berries.
Hormex Rooting Hormone No. 8
Hormex No. 8 is a powerful rooting powder formulated to promote root initiation in semi-hardwood cuttings and houseplants. It uses Indole-3-Butyric Acid (IBA) and is available in different strengths to match softwood, semi-hardwood, and hardwood cuttings. This product is compatible with various growing media, including rockwool, coco coir, peat moss, and soil, making it versatile for hydroponic and traditional gardening setups. Suitable for ornamentals, fruits, vegetables, and medicinal plants, it’s a go-to option for robust cloning success.
Clonex Rooting Gel
Clonex is a high-performance, water-based rooting gel that adheres to the cut end and remains in contact with the stem to supply hormones and vitamins as roots develop. It features a full spectrum of mineral nutrients to nourish new roots during their formative stages. The gel form helps maintain moisture and hormone presence around the cutting, offering strong initiation for a wide range of species and propagation scenarios.
Hormex Rooting Powder No. 16
Hormex No. 16 is a high-strength rooting powder (1.6 IBA) designed for difficult hardwood and tree cuttings. This option is intended for propagation challenges where stronger growth stimulation is required. It’s suitable for a wide array of plant types, with compatibility across common growing media and the potential to enhance cloning success when standard strengths fall short.
Buying Guide
- Plant type and cutting age: Softwood cuttings typically respond to lower IBA strengths, while hardwood or difficult cuttings may need higher strengths (as in No. 16).
- Form factor: Powders are easy to apply by dipping the cutting end; gels offer longer contact with tissue for steady hormone delivery.
- Medium compatibility: Ensure the product works well with your growing medium (soil, peat, coco, rockwool, hydroponics).
- Broad vs. targeted use: Some products are marketed for a wide range of plants; others are optimized for ornamentals, fruit trees, or vegetables. Choose based on your typical collection.
- Freshness and storage: Keep products sealed and in a cool, dry place to maintain efficacy; observe shelf life recommendations.
- Safety and handling: Follow label directions for handling, dipping, and disposal; use gloves to avoid skin contact with strong hormones.
- Cost vs. performance: Consider strength, batch size, and your propagation frequency to gauge long-term value.
