Buying Guide

  • IBA concentration matters: Lower strengths (0.1–0.3%) suit softwood cuttings, while higher concentrations (0.8–1.6%) address semi-hardwood and hardwood cuttings. Match strength to the plant type for best results.
  • Plant variety compatibility: Some species root more easily than others. For difficult-to-root plants, consider higher-potency powders (like 1.6% IBA) or products labeled for hardwood cuttings.
  • Media compatibility: Choose rooting hormone that works across your preferred growing media (soil, rockwool, coco coir, peat moss, water-based propagation). This flexibility reduces the need to switch products when changing substrates.
  • Form factor and application: Powders are simple and mess-free for many users, while liquids offer fast action and precise dosing for water propagation. Consider your setup and skill level when selecting.
  • Ease of use and cleanup: Ready-to-use dusts are convenient, but ensure you tap off excess powder to minimize debris in the potting mix. Clean equipment between uses to avoid cross-contamination of concentrations.
  • Storage and shelf life: Store in a cool, dry place away from moisture and food items. Some products may have longer shelf lives than others, which matters for occasional propagators.
  • Safety and handling: Follow product instructions and wear gloves if needed. Keep away from eyes and mouth and ensure good ventilation during use.

When selecting a rooting powder, consider the types of plants you propagate, your preferred media, and whether you propagate from cuttings or seeds. The products listed here cover a range of strengths and use cases to support successful propagation across common houseplants, ornamentals, and garden varieties in typical American home and greenhouse settings.
