Roadside Vegetation:

The difficulty with road construction, as we've talked before,
is that we build a seedbed on both sides of the pavement that must
indeed be managed. That management of roadside vegetation is
usually the job of the landscape architect and your professional
judgment is expected for controlling volunteer seeding of "weeds."
Look for the seed source; examine the soil surface on which the

seeds germinate. You may not have an immediate solution, but strive
for a natural method of control rather than a typical method. If you
don't respond, herbicides and asphalt mats will be used to solve the
"problem." The task you face most often is to understand the situation
quickly and to offer a solution based on natural processes
rather than artificial methods.
