Rooting powder buying guide: what the tub actually is

Updated: October 2026

You have a parent plant to copy, and amazon.co.uk is offering rooting powder, rooting hormone, a gel and a mycorrhizal pouch in the same browse. This rooting powder buying guide is for that moment: which tile is a basal dip, which is a different job, and which legal class you are paying for. We compared eight amazon.co.uk listings in the [rooting powder comparison](/hub/fertiliser-soil-and-bark-mulch/rooting-powder), plus HSE and GOV.UK pages on plant-protection products. Prices are an October 2026 snapshot in GBP and they move. A qualifying purchase through our links can earn a commission at no extra cost to you. We did not run a lab trial.

What you are actually buying

A rooting powder here is a dip for the cut end before the cutting goes into a free-draining mix. Wet a short piece of nodal wood, tap on a film, and plant at once. Amazon's Plant Root Stimulators node is a sales list, not a chemistry list. Doff's 75 g tub leads it as a seaweed powder. Clonex 50 ml is a gel that reviewers treat as a hormone dip. The wrong tile wastes money if you expected IBA from a seaweed talc.

Seaweed powder, hormone gel, authorised PPP

Read the ingredients line, not the tile title. Doff 75 g describes a natural source of seaweed. Westland's 100 g tub says it is free from synthetic growth hormones and fungicides. Those packs are a method — wet, dip, tap, plant — not an authorised IBA or NAA product unless that pack shows a current MAPP. On this amateur shelf the hormone form is usually a gel. Clonex is the named 50 ml bottle; trade copy talks about IBA and a coat that seals the cut. Doff Hormone Rooting Powder (MAPP 11986) expired on 30 June 2017. The class is not banned. That named tin is. Professional IBA such as Chryzopon Rose 0.1 % (MAPP 17566) is a trained, labelled use, not a windowsill default. If you want cling rather than a dry dip, open rooting powder or gel.

Pack size and the reseller trap

Fifty to 100 g covers a season of home cuttings. Doff 75 g is £5.16 and Westland 100 g is £6.32. The Doff three-pack (B00L2OZ4GI, 3 × 75 g, £7.99, 4.4 from 1,341 reviews) undercuts three singles. It is more grams of the same powder, not a stronger formula. ZINNIAUK's single (B0F9TFBDQ1) was £8.99 with 5.0 from four reviews. The two-pack (B0GTMFHV2S) was £11.99 for 150 g, worse than £7.99 for 225 g on the brand three-pack. Prefer the brand ASIN. Vitax organic powder 6 × 50 g (B0711VWCHX) is £20.42 with no star line. Vitax organic gel 3 × 150 ml (B08BCM7L31) is £14.73 and 3.0 from four reviews; one United Kingdom text said it would not stick to rose cuttings. Clonex at £8.99 is another class, not a larger tub of talc. If the tub is already on the bench, how to use rooting powder is the next page.

Rules you must not skip

A hormone plant-protection claim needs a current MAPP and the right authorisation. Amateur use still follows the label. Professional products need training. Do not treat an old unlabelled tin as if it were still authorised. Decant a little into a dish and throw the leftover away. A wet stem in the stored tub contaminates the rest of the season. The Doff three-pack capture says wear gloves and avoid inhalation or ingestion. Westland says keep the tub away from children and avoid skin contact. BBC Gardeners' World warns that too much true hormone can damage the base. Honey, cinnamon and willow water are kitchen methods, not a labelled auxin dose.

Common questions

Is current Doff a hormone plant-protection product?
The current Doff 75 g natural listing in this set is sold as a seaweed growth supplement. One box-contains block still uses hormone wording. That leftover sentence is not a current MAPP for IBA or NAA on this pack. Treat it as a natural powder dip unless the tub in your hand prints a live authorisation number.
What does organic mean on the Westland 100 g tub?
Westland's capture says natural ingredients and no synthetic growth hormones or fungicides. That is a chemistry claim on that listing, not a licence number we verified and not an IBA dose. You are buying an organic-labelled powder for a compost dip. If you needed a hormone gel, this is the wrong shelf.
When do I need a MAPP number?
You need a current MAPP when the product is sold as a hormone plant-protection product that regulates growth. Amateur packs still need that number on the label. Seaweed biostimulants that do not make a PGR claim can sit outside that regime. If the tin in the shed has no readable MAPP and an expiry you cannot check, do not use it.
Is the Doff three-pack cheaper than three singles?
On the October 2026 snapshot, yes: 3 × 75 g at £7.99 against three brand singles at £5.16 each. You still buy the same everyday powder. A household that only takes a few cuttings a year is better with one 75 g tub than with 225 g sitting open.
Should I buy Rootgrow instead?
No, not for this job. Rootgrow is a mycorrhizal inoculant for living roots at planting. A few rose-cutting reviews mention it in the hole, but it is not a basal dip. Keep it off this comparison.
Can I still use an old NAA tin from the shed?
Doff Hormone Rooting Powder, MAPP 11986, expired on 30 June 2017. An unlabelled or expired amateur tin is not something we can tell you to use. Buy a current labelled pack — seaweed powder or a named gel — and follow that label.
Do unnamed China root-booster liquids belong here?
Not in this set. Those bottles are usually a feed you mix into water, not a basal dip. If the instructions tell you to dose a watering can every week, you are in the liquid-fertiliser aisle.
