Obviously, I'm here to convince you I'm the good guy. And my neighbour is the evil guy, because hge grows gmo corn/soy in rotation.
I have 300 ft of front where I'd like to grow some shit in order to prevent his shit to come on my shit. Sorry for the overuse of shit. I'm French and I love how in the English language words can mean almost anything
I'm growing a lot of medicinal plants, some fruit and nut trees, and I'd like to stick in the same type of shit.
I'm in a zone 4b and it should be going 5 soon. Let's burn more oil, I want a longer growing season.
I was thinking some bamboos, but they tend to be very expensive when so cold hardy. Perhaps some blackberry bushes? Hawthorn? a mi of a few species? woven willow, maybe? I know, I'm the one who'se going to have to look at it. All the time. So...
Does it need to be tall? Are you mainly worried about pesticide drift or physical trespassing? Do you only need screening in the summer?
I think a hops trellis can do pretty good screening in the summer (20+' tall). They die back in the winter.
If you're trying to block pesticides you might want to consider if the plants you fence with would want to be things you eat. Maybe a sacrificial fence species would be a good barrier (willow, poplar, honeylocust, etc)
