Rooting hormone contains auxins that encourage cuttings to form roots faster and more reliably — especially useful for woody or slower-to-root plants. It’s not magic (many soft cuttings root fine without it), but for tricky subjects it noticeably improves success. Here’s how to choose and use it.

Powder, gel or liquid?
| Type | Best for | Notes |
|---|---|---|
| Powder | General use, long shelf life | Dip moist cutting; tap off excess |
| Gel | Even coating, good contact | Popular with houseplant propagators |
| Liquid / concentrate | Batch propagation, control of strength | Quick-dip or soak per label |
All three work; choose by convenience. Decant a little to dip into so you don’t contaminate the whole pot.
When it helps — and when it doesn’t
- Helps most — semi-ripe and hardwood cuttings, and plants that are slow or reluctant to root.
- Often unnecessary — easy softwood cuttings (many herbs, coleus, willow, pothos) that root readily in water or mix.
- Won’t fix — wrong timing, unhealthy cuttings, or poor aftercare. It boosts rooting; it doesn’t replace good technique.
Rooting hormone
How to use it
- Take a healthy cutting and trim just below a node.
- Moisten the base, dip in hormone, tap off excess (more isn’t better).
- Insert into a free-draining cuttings mix, firm gently and keep humid and warm.

Quick questions
Do I need rooting hormone for cuttings? Not always — easy softwood cuttings root without it, but it improves success with woody and slow-to-root plants.
