preparing arborvitae cuttings

hesamaf

I have read some guides about arborvitae semi-softwood cutting propagation. They all recommend to take cuttings from the tip of the branches with a length of about 6 to 8 inches. I took some cuttings this way that their diameter are 2 to 3 mm. Aren't they too thin to be able to form roots? I prepared the cuttings like the picture below.

    Those little shoots may root but I would have made that piece one cutting.

    I don't particularly care for the bend at the base though. You should try to find straight cutting pieces.

    I take a pair of scissors and scratch the bark and cut the foliage as shown... then dip them in a wet rooting hormone such as dip n' grow or clonex and then stick them in about 90% perlite to 10% peat moss and either bag them for humidity or use a tenting chamber made of poly that creates the humid environment. Bottom heat isn't necessary but it can speed up the rooting. You just have to be careful when using bottom heat as to not dry out your media.

    I'll post a few photos of cuttings to follow.

    same cutting after foliage is decreased

    And after scissors are used to prepare the cutting for dipping in a rooting hormone and ultimately to the potting media.

    Sorry but I only have a photo of a Metasequoia cutting showing this but it's done exactly the same way.

    Thank you so much Gardener365 for yhe great photos and answering my question.
    I have another question if you don't mind.
    Can the cuttings taken in this time be kept outside over winter and snow?

  • gardener365

    No. If you don't have a greenhouse - you may simply put all your cuttings in a container and add a few bamboo sticks or other and cover the cuttings with a bag so that the cuttings do not touch the bag... that's what the bamboo sticks are for. And then place the cuttings close to an east or north facing window.

    When large droplets of water accumulate on the inside of the bag/"tent" you'll need to get a paper towel and wipe them off each time this happens so that the bag is w/o water droplets. Very tiny water droplets are fine but large water droplets need to be wiped off.

    If you choose to use dip n' grow for your rooting hormone, hold the scarred cuttings in the solution for 1-minute and then stick them into the media.

    Take care,

    Thanks so much again Dax
    How about using willow water as rooting hormone?

  • gardener365

    You could give it a try. Really, Thuja, on a scale of difficulty to root with 1 being difficult and 10 easy, Thuja is about a 9. They'll root without hormone.

    Just another question
    When exactly do you take that cuttings?

  • gardener365

    If you have extra material you could try some right now or I'd suggest that you wait until the beginning of spring after any frosts.

    I don't have a clue about the year-round weather in Iran, however... or if you live at a high or low elevation which is two different worlds of climate, you understand. You cannot allow them to freeze and ideally you want temperatures between 12C to 24C or within proximately to those temperatures.

    Today I grafted two conifers and am doing the same thing you'll be doing with your cuttings. The bags provide the necessary humidity as to not dry out the plant material. Pretty simple, really.

    You're welcome, take it easy.

    hello sir;

    thank you

  • gardener365

    Grow your cuttings in the shade only. Prepare bed of loose soil (sand, organic matter such as peat moss, perlite; or perlite and vermiculite together.) Do not let the bed dry out. It always stays moist. And mist cuttings often. As often as possible.

    Hope this helps.

    how i should use root hormone ??? how long it takes to be 30 cm hieght?

    thank you so much for your help


  • gardener365

    Depends upon the brand. As to 30 cm height, that depends if strong roots occurred and which arborvitae you are cloning.

    Dip n' Grow rooting hormone has always done me well. 60 seconds dip of cuttings containing hardwood base and then to soil, or, no rooting hormone whatsoever. Arborvitae are very easy to root.

    Semi-hardwood or softwood are not a good idea for rooting. Use wood that is hardwood at the base of your cuttings.

    Hi Dax,

    How did the grafting in October turn out for you? I know that it was a couple years ago.

    Thanks,
    Matt
