If you prune the Montana now, you may not get any flowers in the Spring.
5/10 for leaving the labels, pity they are not attached to the plants!
Again, if you prune too hard you may not get any honeysuckle next year, but on the other hand the wild ones get a short back and sides every Autumn when the hedge cutters come round, and they flower profusely.
I would be inclined to stay your hand and follow the good advice of the previous owner. Do some decorating in the house instead!
Will I start a riot if I suggest men are too free with the secateurs? Always remember 'Growth follows the knife'.
