Among the trees are 3-4 mulberry coppices that are currently maturing fruit. I was thinking i would just prune the branches all back to about 1' and dig up the root ball to move them. By that time i bet the fruit will be mature and maybe fallen off. Will this be bad timing?
Then i started thinking about eventually having a mulberry hedge and i came across truncheons. Basically its a name for something i have heard about many times. Just a relatively large cutting that you stick in the ground to root. Does anyone have experience doing this with mulberry or something similar?
Once i trim the coppices can i just cut the side branches off and stick them in the ground to root? Should i apply any rooting hormone or does that even matter? I know these trees are hardy as can be, i just have not grown one from this method.
Rooting a Truncheon:
"Truncheons are branches, about as thick as a human arm that we can grow into new plants. The branches are cut at about 170-180 cm long. Cut the top of the branch at a slant,
which prevents water from rotting the truncheon. Before planting the truncheon, itshould first be kept under shade for a few days to develop a hard layer over the cut end.
If the cut end is not covered with this hard layer, the truncheon may not root.
Thetruncheon should be planted into a narrow hole about 60 cm deep. The best time for this method is the end of the dormant season when the plant still grows slowly. This
method can be used with most trees which drip a white sap when they are cut."
Anyone have details on the hard layer mentioned?
Here's what I did:
I cut the branch, it was basically just a stick at that point. I buried the fat end of the stick so that some leaves were buried and a leaf but or two were out of the ground. No rooting hormone, I don't even think I exposed any cambium. I then kept it watered. As in, when I remembered. So maybe once a week. But it was spring and we got a lot of water.
The soil was rocky and poor, BUT the tree overwintered and is started to bud out now. So I'm a happy camper.
As you can see, I have limited experience, but I believe mulberry is one of the easiest trees to propagate. At least that's what I've heard.
Good Luck! Let me know how it goes!
The easiest method for getting good rooted cuttings is ground layering, bend a branch to the ground, using two staples (horseshoe shaped heavy wires)
make some narrow scrapes on the stem that touches the ground, just through the bark so the cambium layer is exposed (make several of these going around the stem so you will get even root formation)
next cover this area of stem with soil and water with a vitamin B-12 solution. water this soil patch every other day for two weeks with the solution. Then simply water when the soil is drying after that.
Mulberry will take around two months to form a good root system, when the roots are well developed simply cut the branch so you get the roots and stem above them and plant in a container for moving.
You can also Air layer or you can use a cutting and rooting hormones. If you are going to use cuttings you will need a jar to cover.
Mulberries take a while to root, so the best method is the first one or Air layering. cuttings can work but they will take just as long and you have to have a bell (large enough glass jar to hold the whole cutting).
