Answering the practical needs of gardeners and tree propagators, this guide highlights five rooting compounds that work well for cutting-based propagation. The selections favor products that perform reliably across common home, garden, and greenhouse scenarios, with clear uses for hardwood and softwood cuttings. The top picks suit: beginners seeking straightforward application, hobbyists managing a small collection of trees, and seasoned growers focusing on higher success rates for tougher cuttings.
| Product | Best For | Format |
|---|---|---|
| Garden Safe TakeRoot | Most home and greenhouse cuttings | Powder |
| Bonide Bontone II | Ornamentals, fruit trees, berries | Powder |
| Hormex #16 | Difficult hardwood cuttings | Powder |
| Clonex Rooting Gel | Softwood to mixed cuttings | Gel |
| RootMax Mycorrhizal Powder | Overall root establishment, especially with fungi | Powder |
Garden Safe TakeRoot Rooting Hormone
Best for general home use, Garden Safe TakeRoot promotes rooting in a wide range of cuttings. Active ingredient indole-3-butyric acid mirrors natural plant hormones to initiate root growth. Application involves moistening the cutting, dipping the end in the powder, tapping off excess, and planting. Suitable for hobbyists propagating ornamentals and vegetables. Limitation: efficacy can vary with tougher hardwood species.
Who it’s best for: beginners and casual gardeners who want a simple, reliable rooting boost for standard cuttings. Why selected: straightforward powder format, broad compatibility, and easy preparation make it a strong all-around option.
Bonide Bontone II Rooting Powder
Bonide Bontone II is a ready-to-use rooting powder that accelerates root development for cuttings. It works by coating the clipped end, then placing in moist soil to support early root growth. It’s versatile for ornamentals, vegetables, fruit trees, and berries, with optional use on seeds and bulbs when stored in bags. Caution: results vary by plant type and cutting quality.
Who it’s best for: gardeners wanting a quick-dip approach for a wide variety of plants. Why selected: widely compatible, simple application, and proven track record in many home propagations.
Hormex Rooting Powder #16 (1.60% IBA)
Hormex #16 delivers a strong rooting boost for difficult hardwood cuttings. It uses Indole-3-Butyric Acid (IBA) and is offered in multiple strengths to match softwood, semi-hardwood, and hardwood scenarios. Best when high rooting pressure is required, including trees and other tough propagations. Limitation: higher strength may increase the risk of damage if misapplied.
Who it’s best for: experienced propagators handling challenging hardwood cuts. Why selected: maximum strength option targets hard-to-root species with a reliable rooting stimulus.
Clonex Rooting Gel
Clonex Rooting Gel combines a water-based base with ideal IBA levels for steady root initiation and development. It’s versatile across many plant types and is particularly user-friendly: dip cuttings into the gel, plant into rooting medium, mist, and keep in a warm, moist environment. Rooting outcomes vary by plant species and cut size. Caution: gel texture may not coat very fine cuttings as evenly as powders.
Who it’s best for: growers seeking consistent gel-based rooting with easy handling. Why selected: proven gel formulation, broad compatibility, and simple dipping method make it a trusted choice for many propagation projects.
RootMax Mycorrhizal Powder
RootMax injects beneficial mycorrhizal fungi into roots, supporting strong establishment and vigorous growth. It is positioned as a superior alternative to traditional rooting hormones for many cuttings, particularly when fungi-friendly soil is available. Application involves coating the open end of the cutting with the powder before planting. Limitation: efficacy relies on proper soil moisture and microbial compatibility.
Who it’s best for: growers prioritizing symbiotic root health and faster establishment, including fruiting and flowering trees. Why selected: fungi-based rooting starter offers a different growth push that complements or substitutes hormone-based products.
Buying Guide
Which format should I choose: powder or gel?
Powder is often simpler and longer-lasting, making it a good all-around option for various cuttings. Gel tends to be more precise for delicate or softwood cuttings and offers a tactile control that reduces dust exposure.
What strength is right for hardwood vs. softwood cuttings?
Softwood cuttings generally respond well to standard strength powders, while hardwood cuttings may benefit from higher strengths (as available in Hormex #16). Use the lowest effective strength to minimize damage to the cutting.
Are mycorrhizal products an alternative to hormones?
Mycorrhizal powders, like RootMax, promote root establishment through fungi rather than synthetic hormones. They can be used alone or in combination with hormone-based products for potentially faster root development, especially in challenging soils.
How should I store rooting products?
Store in a cool, dry place away from direct sunlight. Reseal packaging after use to preserve potency. Double-check expiration dates and avoid contamination with moisture or soil.
What about saving cost or maximizing success?
Match the product to the plant type and cutting maturity. For beginners, a versatile option like Garden Safe TakeRoot or Bonide Bontone II reduces guesswork. For tougher cuttings, consider Hormex #16 or Clonex Gel, and use RootMax for a fungal-boosted approach where appropriate.
FAQ

- Do these products affect seeds or bulbs?
Rooting hormone stimulates the formation of roots on cuttings, increasing the likelihood of successful propagation.
It is usually best to choose one product per cutting to avoid conflicting effects; however, some growers experiment with combining fungi-based products and hormones in controlled, non-commercial settings.
Gel offers a cleaner application for delicate cuttings, while powder works well for a wide range of plant types and is typically more forgiving of handling.
For difficult hardwood cuttings, Hormex #16 provides a higher strength option and is designed for such propagation challenges.
Yes, when used as directed. Avoid inhaling powders and ensure good ventilation during handling and application.
Some powders can coat seeds or bulbs for propagation, but follow product-specific guidance for best results.
