Seedless Cottonwood


Seedless Cottonwood

The largest and fastest growing tree in the state. Native
to moist soils along streams and wetlands throughout the

and the success of natural cottonwood regeneration along
riparian areas. The largest living tree in North Dakota is
110 feet tall with a canopy spread of 94 feet.

    I have a seedless cottonwood and it hieght is about 35 ft.. I found a smaller tree growing out of the rrot system from the main tree. Is it possible to transplant? If so, do I cut the main root with the small tree or the little trees themselves?
    I would really like to transplant at another location just because of the shade it provides. The small trees are about 12″ to 18″ high. there are four.

    Depending on where the cutting was taken, try to get some of the root. Dipping the cutting end in a rooting hormone and put it in some water to see if it can start roots on their own. If it does you can then transplant where ever you want them.
