Prevent pollution on allotment

[GabbyGreenfingers]

My allotment is next to a car park. I’m worried about fumes from cars coming and going a few feet from my vegetables.
Does anyone know the best way to protect my plants? Google hasn’t helped much.

A lot of recent studies suggest hedging is highly effective at reducing particulate pollution from traffic, so a good sturdy hedge wouldn’t do any harm (and would provide shelter and a wind break for your crops too). The RHS seem to be promoting cotoneaster franchetii for this purpose, whilst some other studies suggest dense, coniferous evergreens like cedars are most effective.
Anything with a dense habit, furry or heavily textured leaves would probably make a good choice.

I'm not very good with plant names, but I think anything that thrives in a supermarket carpark would be a good choice.

ideally you want something that is evergreen and doesnt have an extensive root spread and wont grow super high.....i'm guessing that most car exhaust is lowish. that way your light wont get blocked and your ground wont be unusable due to roots.
