Chemicals/ hormones for rooting plant cuttings

16 years ago

I have been propogating many of my tropical plants lately using a product called Dip'n Grow. The ingredients are Indole-3 butyric acid 1%, 1-Naphthaleneacetic acid 0.5%, andINERT INGREDIENTS 98.5%. This product has performed extremely well. Most every plant forms roots within 2 weeks. About 98% of the cuttings produce new plants. I have even had Amorphophallus leaves produce new tubers using this product.

I went back to the store where it was purchased and was told that they no longer sell the stuff because ,in their words, the product was just a gimmick.

Can anyone help with some info about these chemicals/hormones?

I always thought Indole-3 butyric acid 1%, 1-Naphthaleneacetic acid 0.5% were a good combination.

How much do you want to know?

How good is your googling? try ~auxin site:.edu for some serious reading.

A gimmick, my foot! Those two hormones have been around for 30-40 years and are used extensively to help root any of a variety of plants. Stupid store clerks!

That's what a did with my first few cuttings and they came out fine. I couldn't tell you how long it took to root but the leaves came on just about the same time as ones with tone on them. I have one that came in last month my wife potted it and didn't use root tone it had leaves on it and they are doing geat and new ones are coming up and the three tips all have good wet looking ends.

Rooting hormone is butyric acid ( labeled a bioactive chemical ) and as a cutting stimulate is ideal. But this acid can damage mature roots or even plants nearby. It is actually considered a hazardous material and you are cautioned not to place it near water supplies. Might just me a "don't sue us if your child gets sick on it' warning but I wouldn't use it on a mature plant. Alfalfa meal is what many gardeners use to help the roots mature. Alfalfa has a hormone that stimulates growth.

Aloe leaf-cutting and root hormon - A question of timing
Q

The rare times I use RH, I use it on something that's dried at least a day. It's really a moot point 'cause Aloes just won't grow a new plant from a leaf. If you've got the time & energy & don't mind frustrating experiments, try it both ways. Doubtful either will work. You can search for other conversations about it here, likely you'll find comments similar to mine, sorry. Shame on Wiki for publishing such nonsense & giving folks false hopes. Edited to add that: Wiki DOES say it's unlikely this will actually yield a plant & they say it in the opening paragraph of their link. So it is less misleading than it could have been.

Rooting plants without rooting hormone
Q

Sure it is. Many millions of plants were propagated from cuttings before rooting hormones came into existence. The three keys to success are: proper timing in taking the cuttings, a suitable rooting medium, and a means of maintaining 100% humidity around the cuttings until rooting has taken place. Old time propagators used sand, mixtures of peat and sand, or anything else that held moisture but had lots of air space. Containers with good drainage, a glass cover- later a poly plastic one - to maintain humidity and a lifetime's experience to know when to take the cuttings.

Thanks albert 135 and goldenginko. The links to the ~auxin site.edu are very helpful,and I want to know a lot more than I do.
I have tried quite a few other products that did not perform well, but the Dip'n Grow worked on almost every plant I tried it on.I can't believe they don't sell it anymore.
I'm kind of old fshioned,and enjoy reading books. Can anyone suggest some titles on plant propogation using hormones/chemicals. For now I'll be busy reading the info online.

Garbird, if you like old books look for The experimental control of plant growth by F. W Went. Went was a Dutch, I think, biochemist who was often taught in university classes as having started this field of study. Amazon had a used copy back on 15 Nov for $4.99+. Probably not much demand for it so it may still be there. Interlibrary loan can almost surly get it from a nearby university.

The curreent name for indolebutyric acid is Indolebutanoic acid. Naphthaleneacetic acid has ca. 10% of the effectiveness of the IBA...forget it. I believe you'll have consistent success using HORMODIN 3(0.3%IBA) It's pretty reasonable in price and is most satisfactory for almost everything. Many greenhouse supply companies stock it...try searching the internet!!!
As Goldengingko said, these chemicals have been around for fifty+ years.

Methinks the clerks needed something to say other than, uhm, well, gee, we really don't know, don't think we sold enough of it to keep carrying it.

Anyone who does any amount of propagating knows what IAA, IBA, and NAA are. Anyone who does any amount of propagating knows the name Dip N Grow and Hormodin.

Anyone who says they are gimmicks...yeah, enough said.

Dip N Grow is a liquid, usually used for harder to root species. Hormodin is a powder, three concentrations available. If you need a source for either, let me know.

Garbird, I usually use an IBA dip then water with Superthrive, but I don't propagate hardwood cuttings.I think the Superthrive has NAA as a root stimulant.

Try A.M Leonard at www,amleo.com for the Dip and Grow.
NAA works on roots some plants that IBA will not root.
There are different forms of IBA. One is potassium IBA which roots a different group of plants.
Once you get roots try liquid fertilizer at half strenght,
this will help get new cuttings to flush new growth.

I've used Snip-N-Dip Hormex for years with great success. I purchased it from Charley's Greenhouse & Garden. Active ingredient is IBA which comes in 3 strengths 0.1%, 0.3% and 0.8%.
