Suggestions for propagating Juniperis stems?

floyd2006January 6, 2007

My neighbor has a beautiful columnular Juniper. Its about 2' x 15' an I think it might be Juniperus Chinesis. I'd like to propagate from stem cuttings, but have never done this before.

Questions:

What would be the ideal width and length of the stems to take? Also planting depth?

I don't have a misting system, but thought about planting in a large aquarium in moist sand? Does this sound like it will work?

Would a heating mat speed up rooting in time for outdoor planting in spring?

I need any advice that can be proffered. Thanks for looking at this.

Take a cutting 4-6 inches long with a heal. apply 0.4% IBA stick in well drained soil. Misting not needed. bottom heat helpful.

Thank you, Georgez5il for your advice. I know I'm on the right path now. How deep should the 4-6 inch cuttings be planted--half way? Is there any chance that the scrap cuttings without a heal might sprout roots? I'm trying to do as many as possible from one tree.

On a four to six inch cutting, I would strip the needles off with my finger nail about half way and burry that potion in the rooting medium, sometimes a small heal will help the rooting process. This injury to the cutting stimulates the rooting process. Another alternative at this time of year is to dip them in a liquid rooting solution (I use Wood's or Dip n Grow diluted 1 to 5 with a 5 second dip)after scrapping off the needles and stick them in a flat of corse sand outside. Water them in and keep watered so they do not dry out. Right now, I have a 4' X 8' bed and three additional flats filled with various evergreen and deciduious cuttings. This method may take a while for them to root, but by next fall you will likely have roots. The following spring they can be planted out is a growing bed.
