I had a comfrey plant growing on my allotment plot in the corner. It was about a metre tall, maybe 30cm wide? Totally within the bounds of my plot. And flowering. I like the flowers and the bees love it, so I left it to do it's thing.
Woman on the plot next to mine has the most perfect (albeit sterile) looking vegetable plot - everything in perfect squares, not a leaf out of place, only vegetables, no flowers. She's there for several hours every morning. She doesn't talk to or respond to anyone on the plot, which is obviously fine.
Anyway, in the past day or so she decided to take it upon herself to come over to my plot and completely flatten my comfrey plant. I could see footprints that aren't mine in the soil. I asked if she had done it and she admitted she had because the flowers will soon turn to seed and spread on her plot.
I'm livid. Surely anyone's plants/flowers/weeds in the entire allotment site could spread seeds to yout plot at any time? Whats she going to do next, destroy all my crops before they're ready in case they spread to her plot? Aibu? How can I get her to stay off my plot without things escalating?
