An entire yard of invasive species
I had a garden years ago before I became concientious about chemicals. DH and I have just bought a house in upstate NY with about 1/4 acre. We saw it early spring before the plants were up in what seemed like well-done landscaping, and so didn't realize until we moved in that the bulk of the plants are nasty ones: english ivy (under the siding, burying the hellebores, trying to bring down the mature maples, growing into the generator, etc.), rose of sharon (the babies are eeeeeeeverywhere), buckthorn (a new invasive species for me to learn! Whee!), pachysandra, and privet. There are a few decent plants buried under the ivy, but the vast majority of what's out there is hard-to-kill semi- or totally invasive garbage.
So, in my naive days, I would have bought a forklife full of Roundup and seed killer and leveled the place. Now I refuse to give Monsanto a single cent, but I'm also not sure that simple weeding and the more eco-friendly chemicals like vinegar are up to the task before us.
What would you do???
