I am intrigued. If I am understanding this procedure, you plant the seed potato in the dirt "under" the bag, then add enough dirt to cover the potato piece. Then cover with mulch such as chopped leaves, grass clippings or some kind of mulch and keep covering it with same until the bag is unrolled it's full height. When the plant dies back are there potatoes in the mulch or just in the dirt under the bag? My sweet potato slips will be ready to go in the ground in a couple of weeks and this is 'very interesting'. I also found some irish potatoes sprouting in my cellar yesterday and have some cat litter plastic mesh weave bags I'd like to plant them in if I am understanding this procedure correctly.
plantkiller46, You understood correctly all except the potatoes should be placed in a closed-bottom bag. The video shows my first prototype Tote with a hole in the bottom that I found unnecessary. Sprinkle a bit of compost, soil, and manure in the bottom of the Tote and cover the seed potato with a little more. Then proceed with mulching and rolling up the sides of the Tote as needed (some folks prefer to use additional soil instead of the mulch). The potatoes are formed within the mulch and can be harvested by dumping/inverting the Tote.
I have never grown sweet potatoes, but a friend has. She says they will grow just fine in the Totes. I hope you can utilize the plastic mesh bags and have a ton of taters!! Thank you for reading and posting your comment. I may have confused others with the difference it what I wrote and the what the video instructed.
Thanks for the update. I'll get to planting tomorrow morning, I am very curious. My in-ground potatoes are a foot tall or so now with the unusually warm spring and I have been adding dirt to their wooden "corral" my spouse made for them, but I am shoveling dirt in the spring to cover them as they grow and then digging them out again when they are mature. That's a lot of shoveling. If I can us bags I can put them along the fence then I can plant onions in the 'potato corral' and utilize the onion patch for other plants! I am excited!! Thanks again for a great idea.
