DaisyI said:What do they grow to when they are rooted to the entire earth?

Potato plants grown in the ground and in containers don't get more than a foot tall and are very bushy. That one is ginormous! Hopefully, little potatoes are growing down there - I can't imagine they aren't. I do think, normally, given the entire earth to root in, they only grow about a foot deep. Potato bags and boxes are only about 18 inches deep. So back to my question: Did you plant the seed potatoes at the very bottom of the first can?

But what a great experiment in potato growing! I can't wait until you dump that container. Take photos of the results and post them for us.

I have some taller bags and the surface of the dirt, like what these cans look like, is up at the top. The potatoes themselves are about 2 feet over the surface of the dirt. Those look to be about that if the surface of dirt is higher. My point about growing to the container is, if the container is taller and you start them at the very bottom and keep adding dirt, they will grow up until you stop adding dirt.

So I know you were joking about earth being the "biggest" container, but since it isn't the tallest, compared to how far down the start is, they would still only get so far up over the dirt surface. If that makes sense.

These look taller because their "ground level" is up higher.
