Silverberry and juniper

Just found a silverberry(I think it's a silver berry as it's my first one, and it has no tag) and I can't seem to find info on them. It's needs to be repotted and trunk chopped, as all the branches are at the top of the poles.Would spring be the best time for this? and whats the general technique for branch ramification? I was surprised to find this as it was at my local home Depot in there discount section-for 10$ it worth the effort.






Also here's a juniper that I pulled from my yard last year that seems to be doing well, as has some more shaping to due down the road-due to the long straight parts on it. Has minor frost dmg due to the crazy weather we has a couple weeks back.

Silverberry = Eleagnus ?
Looks in interesting.
Rare on my side, but they grow very well.
