I am on a seed ban, but I have yet to face consequences for breaching the terms of this understanding.
We are also a clay soil heavy area, and our house is at the bottom of the hill. We are the very last house, and when it rains we do flood.
Rather stupidly, there's the streets electrical unit box outside our house on the street, and it floods multiple times a year. Back when my grandad was alive we had to keep generators for his nebulisers and oxygen tanks because the power went off so often from the flooding. Then over the years as full Fibre broadband has become a thing, they've added the Fibre cabinets next to the electric box, and sort of sunk it into the street, so they also flood.
One of my previous jobs was network planning and we just wouldn't have done this at all, so it often makes me want to throttle the daft eejit who keeps ticking off on these installations.
The frequent flooding also means hardly anything survives planting directly into the ground here, except our peonies which are closer to 50 than 40 years old, and some rogue brambles that have managed to get right behind the rose bushes, and are mostly left unchecked because who wants laceration with thorns on a lovely sunny day.
We get over this by mostly planting in pots but the flip side of that is that on sunny days they dry out extremely fast and nobody dare go outside and water them in case our oversharing, genital obsessed, curtain twitching neighbour springs out for a 4 hour quick chat. Hell truly is other people.
I've come to learn though that if you want to plant something where nothing else seems to grow at all, just throw some nasturtium seeds down once and you'll never have to replant them again.
