Buying Guide: Key Purchase Considerations
Rooting hormones differ in active ingredients, concentration, and formulation. Consider the following when selecting a product:
- Active ingredient and strength: IBA-based products vary in concentration (0.3%, 0.8%, 1.6%, etc.). Higher strengths are often used for difficult or hardwood cuttings, while lower strengths work well for softwood cuttings and softer plant varieties.
- Formulation: Gels, liquids, and powders have different application methods. Gels cling to cut surfaces for longer contact, powders require tapping off excess before planting, and liquids may be easier for some water propagation setups.
- Plant type compatibility: Some products are marketed for ornamentals, fruit trees, or kitchen garden crops. Match the product to your plant species and propagation goals.
- Medium compatibility: Ensure the product works with your growing medium, whether soil, rockwool, coco coir, peat, or water propagation systems.
- Ease of use: For beginners, powders that coat cut ends with minimal mess can be appealing; gels may offer consistent coating with longer tissue contact.
- Storage and shelf life: Store in a cool, dry place and check expiration dates to maintain potency.
