I recommend:
1. Prune to at least pencil thickness.
2. Prune until you see white/cream/pale chartreuse colored pith, any brown to butterscotch colored pith, that cane is cut back further by 1 inch increments until white/cream/pale chartreuse pith is reached, then stop pruning.
3. Balance the bush with after pruning growth ideally pointing in all directions: some north, some south, some east, some west, and some upward. Also, balance for height symetry, no lopsided bushes after pruning.
4. The lower, farther down the bush you prune, the emerging new growths will be fewer, longer, huskier/thicker, and will have fewer but bigger, better formed blooms, with thicker necks that are less prone to nod.
5. The higher up the bush you leave the pruned growth, the more numerous the growth points will be. They will be thinner, shorter in length, with more, but smaller, with less better formed blooms, that will be more prone to nod.
6. Prune out all dead canes along with the weaker, less important canes of all crossing canes.
7. Shrub and floribunda types are less intensely pruned.
8. Hybrid teas and grandifloras are more intensely pruned.
9. Once bloomers are pruned AFTER they bloom, not before, except to remove dead wood.
