Pruning the tomato plants is not something I've given much thought. I only have a vague understanding as to why we pull off the "suckers". A conversation last night with Oliver's cousin has gotten me thinking about changing my ways. He explained that a well pruned tomato plant produces more fruit. As evidence he showed me a photo of his well trimmed tomato vine and then one of of the huge pile of gorgeous tomatoes he'd already picked.
Motivated by what I learned I did some research on the internet this morning. The following video provided a great lesson about which suckers to pluck, why and what you can do with them (stick them in ground and they'll grow a new plant!!). It's probably too late to make difference for us this year; but I'll definitely apply this knowledge next summer.
