If you mean that the container is lined with something that prevents water from draining, then that's the problem.

Agree with rhizo and I'm sorry to say it but those plants are beyond salvaging at this point. The plants are also quite lanky so likely haven't gotten nearly enough sun or sufficient nutrients up to this point. Better luck next year.

Also, you need to plant corn in "blocks" so they pollinate each other. The smallest I've done is about a 4x8'. What I don't like is that all the corn gets ripe at once and there are only the 2 of us! I have read some stuff about freezing corn on the Harvest forum.

I prefer stealing corn from my neighbor! ;) Nancy

Arti, here are some pictures of what garden sweet corn is supposed to look like, just for your future reference.
