Why the duck cant I grow....

I did nt want to take Sam Potter's thread on why he cant grow carrots hostage so I thought I'd post the veggies I cant grow for unknown reasons. Maybe you have suggestions or maybe you have your own impossible yet very common veg that refuses to grow in your garden. For the record I can grow carrots. Takes alot of weeding but I can grow them.

My two crops I cant seem to grow are sweet peppers and corn.  Maybe I dont have the right temps for green peppers but the plants do great, they flower but no fruit. I gave up years ago.  Its the corn that I find baffling. Farmers all around me grow acres and acres and acres of the stuff no issue.  i cant seem to grow the damn things!
I had made a dozen mounds to do 3 sisters, planted 2 seeds per hole and watered, and waited and nothing! Without the corn I cant grow the beans to climb up them ! Its a bit embarrassing too because I got into a discussion earlier this summer with Paul on whether corn is a food or not (see crop rotations and permaculture thread) and the blessed things refuse to grow!

Makes me angry.  Oh well there is always next year.      

You're not alone on the corn Jeff! I wanted to grow sweetcorn in my new polytunnel. I sowed direct since it was getting late in the season. The temperatures ought to have been OK in there, but nada, nicht, niete.... At the moment I'm inclined to blame the seeds, although some were new. Maybe it was just still too cold and damp.
I've now sowed some peas and beans instead - now why haven't my beans come up?!!
