A few months ago, we planted a potato to grow some more. Today, we dug them up.
I spotted a potato, before I put the plant on its side. After a bit of soil clearing, I found the second potato.
First new potato 
Potato 2
We found six new potatoes altogether.
Three new potatoes 
Picked potatoes
The potatoes, which are thick parts of roots called tubers, were attached to the rest of the roots.
When we had all the tubers uncovered, we found the original one. We knew it was the original one because the roots and the stems were attached to it.
I hope the potatoes make good chips.
