I never cut my foliage. I pull the dead outer leaves off but never cut into a green leaf. I am not bothered by rot and I have never seen a borer, knock on wood, and hope I never do. I have friends who cut their leaves off when the tops brown a bit so their garden will not look unkempt. I just water during a drought and the leaves seem to be o.k. If our water table keeps getting lower watering habits may change.
