Until the chemical prep is sprayed on a lusciously green cutover in August killing all the browse so that the Feb replanting can occur without competition.
There have been several incidents where I was excited about the amount of browse in a clearcut during the summer and then, late summer, the clearcut gets nuked. That's always disappointing but I understand the business of growing trees.
Regarding PL, Mark Thomas treated a lot of thinned planted pines areas with Arsenal and wow did it make a difference when the sweetgums and other hardwoods yielded to the sunlight.
