Can I cut piece of branch and put it in the water or soil and it's will grow roots?

to NGA

Yes but it may be easier to buy a new plant. Growing trees from cuttings of spruce and pine are problematic in that you have to know what tree you have, it has to be the right age and the cuttings have to be from the right parts of the tree and at the right time of year.

How about growing from seed?
