Honeysuckle and Montana

I bought a honey suckle and early flowering clematis Montana (flowers now finished).

Both little plants each have just two or three dominant stems than in the last week have grown a good foot due to the warm weather.

Should I just let these do their own thing for now or can I prune to encourage bushier growth?

 

Kriss, I like to pinch the shoots back....now is ideal. Makes for more stems lower down. Both are vigorous plants anyway but, yes, pinch back.
I planted 2 montana clematis in my niece's garden and cut all the shoots back at planting time, viz. last autumn. This spring I pinched back a little more
