I've always cut mine in the winter after our deer season. Ends in JAN. But just because that's the time I'm free.
One word of advice. Cut them above the natural been it'll have. Use'lly 4,5 inchs above the ground.Where when young shoots lean towards the sun. This is almost impossable to get out even this heat. Don't fight it exspecially if ther 6 feet.
I quit takeing out every little been. I cut them 1/2 inch on the big end. Then I JUST RASP THROUGH ALL THE LITTLE BENDS. At the end all you'll have is those long bends there easy to take out.
Save you about half the time heating and bending.
