If your tree cuttings keep going limp instead of pushing roots, the fix is the right rooting hormone and the right dip method. Get those two right and a stubborn hardwood stem can finally throw roots. This guide compares four products gardeners actually buy for tree cuttings, so you can match one to your workflow.
This guide is built by comparing the manufacturers’ published specifications and the patterns across verified customer reviews, so you get each pick’s real strengths and trade-offs instead of marketing spin.
You will see how a gel holds onto a fresh cut, when a liquid dip beats it, and where a starter feed fits the job. Every pick here is chosen with one goal in mind: healthier roots from your rooting hormone for tree cuttings.

How To Choose The Best Rooting Hormone for Tree Cuttings
Tree cuttings are harder to root than soft greenhouse stems. The wood is tougher, the cut surface is smaller, and a powder or thin liquid can drip right off before it does its job. What matters most is how well the hormone stays in contact with the fresh cut — that contact time is what starts root initiation.
Gel versus liquid versus powder
A gel like Clonex is thick and stays put on the cut, so the hormone keeps working on the exposed tissue instead of running down the stem. A liquid concentrate gets mixed with water and the cutting is dipped, which stretches a small bottle across many cuttings. A dry powder is the old-school option, but it brushes off easily. Genuine contact wins with woody material.
What the number on the label tells you
Look for IBA, which is the short name for indole-3-butyric acid, the plant hormone that signals a cutting to form new roots. The percentage is not a strength badge you want to max out — too much hormone on a tender green cutting can slow things down. For most tree cuttings a moderate, consistent dose beats a heavy one.

Detailed Reviews
1. Clonex Rooting Gel 100ml 2 Pack
Our pick — 4.5+★ from 400+ verified ratings; the strongest balance of quality and price.
The thick gel that actually clings to a woody cut instead of dripping away.
If you plan to propagate a lot of tree cuttings this season, this is the volume pick. Two 100ml tubes give you a combined 200 ml of gel, and the single 15ml Clonex below holds just 15 ml — so this pack carries far more product for anyone working through a bigger batch. The formula is water-based with a gel texture built to hold contact on a fresh cutting, which is exactly what a tough tree stem needs.
Clonex has been a propagation standard since 1988, and its lab-made IBA gel keeps the hormone dose consistent from cutting to cutting. The method is dead simple: dip, insert into your rooting medium, mist, and keep things warm and moist. Smooth operator — the dip application means no mixing ratios to juggle. What wins people over is straightforward effectiveness, and the cloning crowd keeps coming back to it.
You will use this gel up fast on a big batch, because it has to be fresh and clean each time. If you want the most cuttings from one container, some growers still pick a liquid concentrate like the Dip’N Grow. For most home growers, though, what counts is that roots show up.
What Earns Its Spot
- Water-based IBA gel engineered to hold extended contact on the cut
- 200 ml across two tubes for longer propagation runs
- No measuring or mixing — straight dip application
- Made under lab conditions, consistent dose per dip
The Trade-Off To Know
- Gel runs out faster on very large batches than a concentrate
- Root development pace still varies by tree species
Settle on this if: you want one proven gel and enough of it to keep dipping through a full season.
Think twice if: you only ever root a single small stem and would rather not keep a large tube on hand.
2. Fertilome Root Stimulator 32 oz
Not a dip at all — it is the soil-drench feed that settles a new tree in after planting.
Here is a piece of the puzzle that trips up a lot of beginner propagators: this is not a dip-and-root hormone the way the gels are. It is a 4-10-3 liquid starter feed — 4% nitrogen, 10% phosphate, and 3% potash — with indole-3-butyric acid as its active ingredient for starting root formation. You mix it into water and drench the soil around a transplant, which is why it belongs in the toolkit right after a cutting has actually rooted and gone into the ground.
One 32 fluid ounce bottle covers trees, shrubs, roses, annuals, and perennials. Mix it at a 3.5:1 ratio (3.5 parts water to 1 part concentrate). Buyers report it revives transplants in poor clay soil: “Rescued a raccoon-dug plant: repotted in good soil, kept shaded/moist with diluted solution; stems perked in days, new growth in a week.” If you are moving a young fruit tree or shrub from pot to soil, this step reduces the setback.
Manufacturer claims aside, your results will track how you apply it — the label rate changes with plant size and type, so a heavy hand is not the move. Treat this as the follow-up feed after rooting, not the rooting dip itself, and it earns its place beside a gel.
Where it fits in the process: After a cutting roots and you transplant it, this 4-10-3 drench supports early root formation during that fragile settling-in window.
Read the dose first: Application varies by plant size and type, so match the label rather than pouring by feel.
Reach for this if: your trees are already rooted and you are moving them into soil or potting them up.
Look elsewhere if: you need a hormone to dip a bare cutting before it ever roots.
3. Clonex Rooting Gel High-Performance Rooting Compound – 15ml
The small starter tube to try before you commit to a big gel pack.
This is the same water-based IBA gel formula as the two-pack above, just in a 15ml tube. If you want to test how your figs or maples respond to a gel dip, this is the low-commitment way in — same dip application, same warm-and-moist routine, same broad plant-type coverage. The 200 ml in the bigger pack dwarfs this 15ml tube, so this one is for small projects, not a full season of propagation.
The buying math is where you have to be honest with yourself. A 15ml tube is a modest amount, and the strongest single gripe across reviews is value for money — several buyers wish they got more gel for the outlay. Effectiveness feedback lands mixed too, which usually points to species and technique rather than the formula itself. A soft green stem and a gnarled old hardwood branch simply do not respond on the same schedule.
Think of this tube as a sampler. It lets you learn the dip habit and confirm the gel works with your cuttings before you scale up to the larger pack.
What you get: The real Clonex gel in a compact 15ml tube with the same simple dip method.
Size it right: This is a handful of cuttings, not a full propagation run — plan accordingly.
Best for: a first-time gel user or someone rooting just one or two stems.
Not ideal if: you expect many cuts this season and would rather buy the volume once.
4. Dip’N Grow Rooting Solution 2oz 726305
A little concentrate that stretches far — and roots figs fast.
For the fig, rose, and tomato crowd, this liquid concentrate is a long-running favorite. It is a dip application, and the mix ratio is 1:X, so you dilute what you need and the bottle goes a long way across many cuttings. Owners mention it roots tree cuttings fast: “Dipped the stems about 5 days ago and roots are starting to form.” That is the whole promise of a good liquid — get the dose right, dip, and wait.
One physical notice before you buy: the product data flags leakage issues, and this is a 2 ounce bottle, so treat the cap and seal with care when it ships and when you store it. Several users also advise wearing gloves and not breathing the fumes, which is standard good practice with a concentrated liquid hormone. Handle it like the chemical it is and it behaves.
Compare it to the Clonex gels and the trade-off is clear: the gel is thicker and stays put, while this liquid needs a clean dip and a careful mix. If you prefer the control and economy of a concentrate and mostly root woody stems, this one works.
The reason it lasts: A 2 oz concentrate at a 1:X mix ratio stretches across many dip sessions.
Handle with care: Leakage is a reported issue and the liquid is concentrated, so seal and glove up.
Suits you if: you root figs and hardwoods regularly and want a concentrate that goes far.
Skip the hassle if: you would rather not mix and just want a no-fuss gel.
Know the Specs
Form: Gel vs Liquid
A gel like Clonex is thick and clings to the cut surface, so the hormone stays in contact with the fresh wound longer — useful for tough tree stems. A liquid concentrate is thinner; you dilute it and dip, which spreads a small bottle across more cuttings but needs a clean, quick dip. The Fix: with woody material, longer contact tends to help, so start with a gel and use liquid for volume.
Active Ingredient and Feed Numbers
Look for IBA (indole-3-butyric acid), the plant hormone that starts root formation, on the growth products. Separately, a starter feed like Fertilome’s carries an N-P-K ratio of 4-10-3 — 4% nitrogen, 10% phosphate, 3% potash — for after transplant. The Fix: use the hormone for the dip and the feed once the cutting is in soil, not the other way around.

The Bottom Line
For most people rooting tree cuttings, the rooting hormone for tree cuttings winner is the Clonex 100ml (2 Pack), because the thick IBA gel holds contact on a tough cut and the 200 ml carries the season. If you mostly root figs and hardwoods and want a concentrate that stretches, grab the Dip’N Grow Rooting Solution. And once your cutting has rooted and gone into soil, the Fertilome (10645) Root Stimulator is the one to reach for to support that fragile transplant stage.
