I planted a potato that was sprouting in my veggie basket at the start of lockdown.
Today I dug it up and now have 32 baby potatoes from one supermarket potato.
I did it is an experiment as I’m not a Gardner by any means but I’m really surprised at what I’ve managed to achieve.
The more soil or compost you have covering the potatoes the more potatoes you will get.
If you can get something deeper than a builders bucket, so much the better.
I only have around 30 plants in the ground. All the rest are grown in 30 ltr buckets. They come out like little bars of soap, absolutely unblemished.
Perfect .. plenty of holes for drainage and put in six inches of compost and put in 6 or 8 spuds. Once they pop through the compost just cover them with
another 12" of compost. Keep repeating until the bin is full. Stand it in full sun so as to get all the benefit of growth in the remainder of the summer. Leave them in the compost even after all the foliage has collapsed.
I have done similar in the past using car tyres with the walls cut off .. just kept adding a tyre and more compost after the spuds emerged.
As the nutrients have been used up by the potatoes, it would be hopless to try and do the same again. The next potatoes would be tiny like marbles.
What I do with old potato compost is just add some fresh compost to it and mix well and then sew carrots in it. There is very little resistance in old compost and the carrots will grow long and straight. Works every time.
