Suitable for a broad range of plant cuttings, Clonex is well-regarded for consistent clone success in both home and professional settings.
Hormex Rooting Hormone #16 For Hard-to-Root Cuttings
Hormex Rooting Hormone #16 offers high potency (1.6% IBA) ideal for hardwood and difficult-to-root cuttings. The powder format allows precise dusting on cut ends, helping to accelerate root initiation while supporting robust rooting in a variety of plant types, including ornamentals, fruits, and trees. Hormex products are designed to work across multiple growing media, making them versatile for both indoor and outdoor propagation projects.
Hormex Rooting Hormone #3 All-Purpose Powder
Hormex Rooting Hormone #3 provides an all-purpose option with a balanced IBA level suitable for a broad spectrum of cuttings. Available in multiple strengths, this powder helps speed root formation while remaining compatible with common propagation media such as soil, rockwool, coco coir, and peat moss. It’s a practical choice for gardeners seeking reliable results across diverse plant types, from ornamentals to edibles.
Bonide Bontone II Rooting Powder For Quick Roots
Bonide Bontone II Rooting Powder speeds root development in cuttings and can also be used with seeds and bulbs by coating them prior to planting. This ready-to-use dust contains plant growth hormones that stimulate root production in both hardwood and softwood cuttings, making it versatile for ornamentals, vegetables, fruit trees, and berries. Its powder form allows easy dipping of cut ends before transplantation into moist soil, supporting quick establishment of new roots.
Root Drops: Liquid Rooting Hormone For Fast Propagation
Root Drops by Southside Plants is a liquid rooting hormone designed for flexibility across propagation methods. Its dual-action formula leverages a low-concentration Indole-Butyric-3 Acid plus vitamins to accelerate root growth while minimizing transplant shock. It works well in water propagation, soil transplants, and alternative media like LECA or sphagnum moss, making it suitable for many hobbyist and professional setups. This liquid format allows precise dosing with a dropper, enabling careful management of rooting intensity.
Buying Guide: Key Considerations For Selecting Rooting Hormones
- Plant type and cutting hardness: Hardwood, semi-hardwood, and softwood cuttings may require different IBA concentrations. Higher strengths are typically used for more difficult-to-root species.
- Format and application: Gel, powder, and liquid formats each have pros and cons. Gels stay in place on stems, powders provide direct end-dusting, and liquids offer easy dilution for water propagation.
- Medium compatibility: Check whether the product works with soil, rockwool, coco coir, peat, or hydroponic media. Some formulations are versatile, others are media-specific.
- Shelf life and storage: Store away from heat and moisture to preserve hormone potency. Some powders can clump if exposed to humidity.
- Safety and handling: Use gloves and follow label directions. Some products can irritate skin or eyes; ensure proper ventilation when applying.
- Cost and yield: Consider how many cuttings you typically propagate and the expected root success rate. Higher potency powders may reduce days to root but cost per cutting varies by product.
When planning a propagation project, it helps to match the rooting product to your plant species, your preferred application method, and your growing medium. A gel like Clonex is excellent for delicate cuttings needing comprehensive coverage, while powders such as Hormex #16 or Bonide Bontone II can provide quick, straightforward end-dusting for a wide range of plants. Liquids like Root Drops offer dosing flexibility for water propagation and varied substrates. Always start with the recommended strength for your plant type and adjust as you gain experience with your propagation routine.
