Propagation by cutting(s)

[october]

Last year, I experimenting with an arborvitae cutting and it was successful. This cutting was close to 1". If I remember correctly, it was put into a blend of turface, river sand and some bark. The important things are temps and humidity. This cutting was kept in an area that was a constant 80 degrees F and misted a couple of times a day for many weeks.

I sold this cutting last year. However, I have seen it recently and the trunk is even thicker. I am wondering if maybe a 2" arbi cutting might take.

Interesting thread. Ill tell you that bougainvillea can root in south Florida from 2+ FOOT trunks. along with about 10 other varieties. Although finding material that large or impressive is rare, it does happen.
there are a lot of techniques to get 90%+ success on junipers with up to 1" trunks. I was shocked when I went to a regional grower of Shimpaku, all in 6 inch pots with 1/2-1.25" trunks all rooted and less than a year old. I takes me years to grow them that big! needless to say I took detailed pics and am re-assessing my propagation techniques.

So are you holding out on us or will you share the magic?

lol. Its not a big secret, but yeah, I'm not sharing it as I'm not doing it yet and haven't mastered it. I will tell you I have 5-8 inch tridents I'm working on rooting. I'm not really expecting
anything but will show you next year or the year after if anything takes by this technique, although maybe not just how its done.

While I am sad that you can't share...I understand because it is (trade secret) for your business.

I like & appreciate that you came straight out and said it though and not dance around the issue like a politician.

Please keep us posted.

Dario, did you ever try this?

IF you are referring to what Daytona1911 mentioned, no. I have no idea what the "secret" is.

Re: yaupon and boxwood, I managed to propagate 2" cuttings from them. I tried trident maple and they were growing but the place they are on got flooded (burst irrigation system) for weeks and they died. I have another 1.5" trident cutting going right now. This one is elevated.

why not just do air layers to be sure instead of taking the chance with a cutting..?

Air layer may slow down the mother plant. Both have their advantages and disadvantages.

I take cuttings 20 cm+= 8"vrom anything I can lie my hands on.
I plant in washed sieved river sand. I dont use hormones...But smaller cuttings root much faster than large ones.
The trick for me with large diameter cuttings is to take longer than normal cuttings...the thicker the trunks is the longer the cutting...Not sure of the reasoning behind but I suspect you have more trunk and more stored energy..
This is a Zambian village where large poles are stuck in the ground...and you can see them growing.
Some of my cuttings.

Around here, people are successful getting very thick cuttings (e.g., 3" to 1' diameter) to root for olives, bougainvilleas, and pomegranates. There are probably other species I'm forgetting, but those seem to be the most common. In fact, common olive collecting guidance recommends basically making the tree a glorified cutting by flat chopping above the roots.

Ultimately so many factors are at play when rooting cuttings, it is hard to isolate the effects that one variable, like trunks diameter, has, but with good propagation practices (high humidity, bottom heat, hormone, etc.) and patience, I think many trees will root from thick cuttings. I've got many different species of thick cuttings currently in my propagation chamber (flowering quince, Chinese quince, trident, olive, crape, holly, Japanese maple, ficus, etc.). Hopefully a good portion of them root.

Chinese elm cuttings. Both close to 2". Growing in Napa floor dry. Bottom heat. Constant moisture. Cut from parent plant 2 months ago. Growing fine on own roots now.

OKa bit off subject but didn't want to start a new tread on a simple question. Has anyone tried miracle grows root hormone? Thinking of starting some cuttings from my mother-in-laws juniper before she trashes it and the nursery by me only has miracle grow power. Everything else is liquid.

If the active is indole-3-butyric acid (IBA) which I believe it is...then it should be fine.

 

[M. Frary]

Used it on other kinds of cuttings not trees and it works fine. When I do use hormone I usually use root tone brand powder.

 

[jcrossett]

OK well thanks. I'll be letting you know in about 6-8 months how it worked.
