What is Yates Clonex used for?
Clonex is not a new kid on the block. Since it came out 20+ years ago it's been the staple for indoor plant hobbyists and outdoor gardeners for plant propagation ever since, and still is. Search 'clonex' in your favourite indoor plant page or forum and you'll see constant recommendations. Yates Clonex works a treat for initiating root development and growth when propagating cuttings. But wait, there's more...
What's Clonex Purple for?
There are 3 strengths in the Clonex range, Green, Purple and Red. It's Purple that's considered the all-rounder for both soft and semi hardwood cuttings - that's the domain of us indoor plant hobbyists.
A softwood cutting is one taken at the plant's tip, where new growth is taking place. At the top of any stem will be the current season's growth which will usually be brighter green, soft and pliable (the softwood). Further down the stem is growth from earlier in the year, called semi-hardwood. It'll be older so is typically a darker green in colour. Towards the bottom of the stem is last year's (and older) growth, normally brown, woody and quite literally harder - which is why it's called hardwood.
When propagating indoor plants it'll mainly be softwood cuttings you'll be clipping and dipping, occasionally semi-hardwood. That's why Clonex Purple is our go-to.
What's in Clonex?
Manufactured in Australia under pharmaceutical laboratory conditions, Clonex contains a blend of root growth hormones, anti fungal agents, vitamins and minerals in a stable gel base.
The key ingredient is IBA which are synthetic Auxins. Auxins are for both initiating and promoting new root growth. IBA is non-toxic to plants (well, doh), but more importantly, is also super stable.
Clonex also contains anti-fungal agents to help protect delicate cuttings from nasty fungal and microbial infections and disease. It's also got 12 of the essential macro and micro nutrients to directly feed newly emerging roots the nutrients they need, at the moment and place they need them, plus vitamins to reduce propagation and transplant stress.
Clonex Purple contains 3g/L active constituent. Formulated for softwood and semi hardwood cuttings. Called "the perfect all rounder".
How do you use Clonex?
You quite literally dip and grow! Dip the freshly-snipped end of your cutting in to the Clonex gel down to about 1.5cms then plant in the substrate of your choice. Get the full cutting prep and Clonex directions for use here >
Unlike some powders and liquids, Clonex Rooting Hormone Gel is not mixed with talc, or dissolved in water. It instantly and completely seals the cut tissue, which does 2 things for your new cutting.
It helps prevent infection and disease getting in, and stops embolism (where air gets in and prevents the stem from taking up water - the same reason florists tell you to cut stems underwater). A dreaded embolism can be one reason your cuttings die instead of root and flourish. Being a gel, it also stays in direct contact with the stem throughout the rooting period. A benefit compared to growth hormones that are diluted and mixed with water.
The humble Clonex Rooting Hormone Gel has been the subject of numerous scientific studies throughout the world over the years. Clonex consistently outperformed propagating powders and liquids across a wide variety of plant species to deliver increased strike rates and production, along with quicker and more prolific root growth.
Although they say you can dip your cutting directly in to the jar of Clonex, I'd personally recommend tipping some out in to a sterile container and dipping it that way so there's no risk of contaminating the rest.
How should you store Clonex?
Since Clonex is stable, and in gel form, you can store it in any cool, dry place. It does not require fridge storage or any fancy prep.
PS: How good is the price?! Clonex comes in a decent sized 50ml jar (about 7cm tall x 4cm wide).
Propagation Pro Tips
I don't know if I'd call myself a 'pro' but I do know I've had better results when I use any growth booster along with an NPK plant food. Keep in mind the mainly inorganic, free-draining substrates we often prop our cuttings in is also largely deficient in nutrients - at a time our babies need more than usual to support fast, healthy growth.
During the early vegetative stage (that's when a plant is focused on roots, stem and leaf production), plants have a higher nitrogen requirement (that's a macro nutrient). Not much of a pro tip I know. Plant foods tell us the Nitrogen amount first (that's the first number in the NPK ratio, such as 9-3-6 - 9 being Nitrogen).
BUT also matters is those micro nutrients. For example, during formation of new cells, calcium is needed in a big way (but in small amounts). It's only a micro-nutrient after all. But a plants ability to grow and thrive is determined by the nutrient it needs the LEAST of - not the most! Mind blown, I know.
Except there's a problem. Some nutrients our plants can move around to where they're needed - like Nitrogen. Some are immobile - like Calcium. So once there's a deficiency, that's it for the life of that cell in the affected stem / leaf. No fixing that later. Your plant needs it at the time they're putting out new growth.
Moral of the story: Don't stop feeding when you propagate! Use your same NPK food you give your mature plants (just check if the dose changes for hydro / leca / propagation - I usually half the dose). Ideally you want a food that's urea-free so you don't accidentally burn your delicate new roots and leaves, and one that has both the big guys (NPK) and the little guys (especially calcium!).
