If that's the only place you have, then I would go ahead and plant your toms and peppers. Most of my container toms and peppers only get 6 hours of sun, and they do fine. Don't know where you are, but my zone is similar to the Twin Cities, but gets a bit colder at night. Toms won't set fruit if it gets too hot, so maybe if yours are a bit cooler, they'll produce more...worth a shot, and how else will you know? The worst that could happen is you get low production, but you should get something. You can always do what VF suggested and plant a few in containers for back-up.

Can't promise you a VERY good bloom, but it will bloom nevertheless. I have two of them in a similar to yours conditions and they bloom.

And here is a photo of the hoophouse almost completed. I cover the door at night but need to build a door for it and double check the seams etc. The ventilation area between the two ridgepoles is functional but it will be a week or two before I have it finished out based on my original design...had to finish it up quickly due to the cold temperatures we are experiancing. It will be near 32 degrees again tonight. Sorry for the photo quality. Most of these last photos were taken very late in the evening. Jay

In my experience, the sunburn has never been horribly disfiguring, and the next year's new growth tends to cover it up. I don't see anything wrong with seeing how well your plants handle the sun and then trying an intervention if sunburn is a big problem. Your individual landscape situation will dictate your options. For example, my Tom Thumb Gold was planted in a bed near the street four years ago. Like you (coniferbros, that is), I didn't view a shade cloth as an acceptable aesthetic option in that location, and I was willing to suffer some burn. In the end, I think I made the right decision, but I've made just as many (or more!) wrong decisions when it comes to gardening in general...
