Systemic removal of wild raspberry?
I have a sunny glade in my woods that has been commandeered by wild raspberry. It has to go as the area has become totally overgrown and unsuitable for walking through. I started the removal process using my brushcutter, but stopped after quickly realizing that the stuff would immediately grow back. Is there a systemic herbicide that will get to the roots and clear it out of there once and for all, and if so, should I wait until the canes begin to leaf out?
