When is the best time two cut or trim a banksia rose.?

[1] Banksia rose blooms once, and early, in the year. [2] Early flowering's done on old wood. Old wood refers to what the plant has going into the dormant season. Later flowering's done on new wood. New wood refers to springtime growth, after the dormant season. [3] So banksia rose pruning should be done right after flowering. And it's generally best not to remove more than 1/3 of the least attractive or oldest parts of the plant in any one year. [4] However, there's the rule of the "d's". Prune whenever a plant part has ended up damaged or dangerous; or whenever it's dead, diseased, or dying. The bloom may be affected that year. But it'll bounce back the following.
