What size obelisk for tomatoes?
As a follow up to the "attractive tomato bed" thread, I have a question. I am hoping to grow a few indeterminate tomatoes and have decided I'd like to bite the bullet and buy a few obelisks for them. First, will this work? Second, how tall must they be? I've read some about pruning tomato suckers for productivity, but haven't found much on pruning for size. Is it possible to prune to limit height and still get good production? I've read about "topping off" 30 days before frost to get tomatoes to ripen.
My concern stems from the small size of my potager. It has been a long time since I've grown tomatoes in the ground, and I forgot how big they can get. What can I expect in my zone?
My obelisk choices are 5', 7' and 8'. 8' would look ludicrous in my small space, I think (the entire potager is only 14.5' wide and with a one foot lift in the raised bed, the obelisk would end up 9' in the air). From a visual standpoint, I think 5' would be about as big as I'd really want in the space. Is it a stupid question to ask if I can prune the tomatoes to keep them within that size? I figured only those of you here in the potager forum would understand a desire to balance the production of the plant with aesthetics! LOL. What I'm suggesting may be heresy.
Thanks so much in advance if you can help educate me!
