I know camps are divided on the trim/no trim issue, but I took exception to Randy Lemmon along our Gulf Coast areas telling everyone that no one but Texas trims crepe myrtles. I do trim some every 3rd year, but trimmed one the drought got-and it is still alive and blooming again. I also live closer to the Big Thicket and fight swarms of bugs...I do know some of the older varieties reached skinny limbs 109' into the air and quit blooming - these were chronicled some years back over in lower Ga/Al, but I don't know what became of them. We don't just trim back to a knob, some folks trim them to knobs one year, then after 3 years trim the newer growth into a pattern that would resemble a tree canopy instead of long skinny overgrown octopus arms. Thanx tho for the vindication- I KNEW I remembered trimmed crepes when last I was over there. Darn skeeter in the house again...
