This is a subject I'm inexcusably ignorant about for someone who has
gardened so long.

I tried to look on-line, but got only general info about NPK.

What I want to know is ***WHEN**** in relation to pruning.

I usually prune 3rd week in Jan.

Because of heavy rains (yay!) should I prune earlier or later? I
think earlier, if any, because later will give roses time to leaf out
before pruning.

Any info relevant to So. Calif coastal much appreciated.
