OK here it goes: showing my ignorance! I have grown potatoes (many years ago) in the ground and dug them up to harvest them. So what I don't understand is how to harvest them from containers. I read about planting in a trash bin and adding soil at intervals as the plants grow. Seems potatoes would form at the bottom first, so how and when does one harvest them? Sorry to be so dumb about this, but love new potatoes and want to try growing them again. I am no longer able to get down on my knees so container gardening will be my method in the future.
Thank you anyone and everyone for explaining this to me!
