So this one explains my avatar pic. Yes, that is a 4.61 lb. sweet potato from my last harvest I'm holding up next to my head. My garden is completely organic and no-till. I never use any synthetic fertilizers or pesticides and accept the occasional loss of a plant or tomato. When we moved into our home the garden had sat feral for a couple of years and it took me two seasons to build the soil back up.
Last May I planted 3 slips in my garden and completely neglected them all summer. I did not weed, water, or fertilize them at all. The vines spread down the garden row and provided an extra layer of mulch for my pepper plants.
FYI: The biggest one weighed 5.13 lbs. The one featured in the video thumbnail is the second biggest at 4.61 pounds. Guess I have a personal best record to beat next year.
