I'm laughing about the neighbor thingy, I don't have any really. Except for the rental house the closest neighbor is pretty far away and at that, there are only a couple of them.
If the horse manure is dry though and you mix it in with your soil well, there shouldn't really be any smell to disturb your neighbors. You might want to give some a try at the end of the season and let it sink in over the winter.
I'm looking forward to the pictures of your nice, neat garden. I always appreciate the time it takes to keep it that way. Mine to me always seems chaotic.
I finally got the darn thing weed free today. Well, about 90% anyway. You can never get all of them completely.
Those pots in the link look like ones I tried some years ago for the koi pond. They kind of reminded me of roofing felt without the tar coating. They worked ok I suppose, but had a tendency to collapse a little. But then again, they were in the pond and koi are such destructive little buggers. They were constantly digging around in the pots and eventually got all the soil and pebbles out of them, along with the plants. I gave up many years ago trying to keep water lilys in the pond because of them. I have lots of mint growing around the edges and an occasional floating plant in there, but that's it.
I think they would probably be ok in the garden, but you might need to prop them up somehow. What had you planned on using them for? Could make a difference...
Let me know when you are going to can and I'll share some of the recipes I use for mine if you'd like. I look forward to you sharing some of yours also! I do not pressure can though, damn things scare me!
If you don't want to can, you can always dehydrate your excess produce too. Saves on lots of space and it's like magic when you cook with them and they pop right back to the way they were. But you know that already.
By the way, the soup was delicious!! Thank you!
