Just a few weeks ago my tomatoes were looking TERRIBLE. Viruses, fungus, chewed up leaves, wilty, evertyhing. But all of the sudden there are lots of green suckers coming up. I figured that the new leaves would provide sustenance for the plant, so I cut all the old leaves off. I have been rewarded with nice, green shoots... then flowers... and now more tomatoes are being set! This is happening with both my determinate and indeterminate types.

Is this a normal occurence? I am starting to wonder if I can't keep these same tomato plants an entire year. I always read they were done for once the summer heat and humidity set in. What's the longest you've kept a tomato for?
