Garden Safe TakeRoot Rooting Hormone
Garden Safe TakeRoot is a powder rooting hormone designed to help cuttings form roots efficiently. Its active ingredient is Indole-3-butyric acid, a plant hormone naturally involved in root development. To use, moisten the cutting ends, dip into the powder, shake off excess, and plant. This approach is straightforward for home gardens and greenhouse setups, accommodating a wide range of species. The 2-count packaging offers value for those propagating multiple plants or trying several varieties.
Root Drops Liquid Rooting Hormone
Root Drops uses a liquid formulation with 0.025% Indole Butyric-3 Acid, combined with vitamins to support rapid and robust root growth. The liquid format is versatile for water propagation, soil transplants, and specialty substrates like LECA or sphagnum moss. It helps reduce transplant shock by providing consistent root development during transitions, such as moving cuttings from propagation to potting. A few drops per quart of water are typically sufficient to support the first two months of establishment.
Bonide Bontone II Rooting Powder
Bonide Bontone II Rooting Powder provides a ready-to-use option for quick rooting of cuttings and transplants. Dip the clipping end into the powder and place it in moist soil to initiate root growth. This versatile powder is also suggested for seeds or bulbs—coating them before storage or bagging helps prime them for faster rooting. It suits ornamental, vegetable, fruit, and berry propagation, making it a dependable choice for mixed indoor and outdoor gardens.
Houseplant Prop Drops
Houseplant Resource Center’s Prop Drops are a natural, seaweed- and humic-acid based rooting promoter designed to stimulate rapid root growth and reduce transplant shock. The liquid formula is easy to apply with water or soil, avoiding messy powders. It supports a broad range of houseplants, including popular varieties like pothos and monstera, and comes with a two-year shelf life. This option emphasizes gentle, nature-inspired propagation with accessible instructions and a helpful PDF plant guide included with purchase.
Hormex Rooting Hormone #8
Hormex Rooting Hormone #8 is a semi-hardwood strengthening option formulated with 0.8% IBA, designed to accelerate root development in intermediate growth stages.

Hormex offers various strengths to tailor rooting to plant type—softwood, semi-hardwood, or hardwood cuttings—making it a flexible choice for diverse propagation projects.
Hormex Rooting Hormone #16
Hormex Rooting Hormone #16 is the highest-potency option in Hormex’s line, designed for hard-to-root woody plant cuttings. With 1.6% IBA, this formulation aims to deliver strong and reliable root initiation for difficult species. Like other Hormex products, it is part of a broader range of strengths to ensure appropriate rooting for various plant types, including ornamentals, fruit trees, and woody perennials. Use with compatible growing mediums to maximize cloning success.
Buying Guide: Key Purchase Considerations
- Propagation medium compatibility — Powder forms often excel in soil and traditional cuttings, while liquids can be more forgiving in water-based or mixed mediums like LECA, sphagnum moss, or pon. Consider your primary method (water, soil, hydroponics) when selecting.
- Active ingredient and concentration — Indole-3-butyric acid (IBA) is the common active ingredient; concentrations vary from low-strength (0.1–0.3%) for softwood cuttings to higher levels (0.8–1.6%) for hardwood or difficult plants. Match the product strength to the plant type and propagation stage.
- Form factor and handling — Powders offer quick, straightforward dipping but can create dust and require careful tapping to remove excess. Liquids reduce mess and can be easier for bulk dipping, but precise dosing matters. Choose based on your comfort and setup.
- Transplant shock and recovery — Some formulations emphasize shock reduction and faster establishment, which is valuable when transferring cuttings to pots or larger containers. Consider products that provide ongoing support for initial weeks after propagation.
- Natural vs. synthetic emphasis — Some customers prefer natural or plant-based blends (e.g., seaweed extracts) for gentler propagation, especially for sensitive houseplants. Others rely on traditional hormone powders or concentrated formulas for reliability and speed.
- Ease of use and instructions — Look for clear usage guidance, whether you’re a beginner or an experienced propagator. Some products include additional plant guides or companion tips to improve success rates.
In summary, the best choice depends on your propagation goals, the plant varieties you cultivate, and your preferred propagation medium. Powder options provide quick, direct rooting for cuttings, while liquid formulations offer flexibility across water and soil systems. For challenging species or woody plants, higher-potency options may yield better results, whereas beginner-friendly products with gentle blends can reduce risk during early-stage propagation.
