I recently uploaded a video to my Youtube channel which showed me emptying an old tub of soil where some potatoes had self seeded. I let the potato plants grow, flourish and then die back themselves but I didn't water them at all. Instead I left nature to do its thing, they only got watered by rainfall. It was an experiment more than anything to see what would happen with self seeded potatoes, whether they would provide a harvest or not.
Watch the short video here on Youtube to see whether we got a harvest from the self seeded potatoes.
I'm currently working on building up my Tomatoes & Tulips Youtube channel so I would really appreciate any follows. It would be great if you would join me on my journey towards a more self sufficient lifestyle and hopefully one day to buying a smallholding.
