I usually take off the lowest stems on my tomato plants, just to make it easy to water without splashing too much foliage. I don't usually think about suckers- can't remember if I removed them or not last year. This time, I left them on. Noticed one day it had been too long since watering, and some foliage was yellowing, droopy. They didn't recover after watering, instead the stems turned yellow and began to drop off. I went out there yesterday to cut the yellowed stems completely- it was maybe two or three on each plant. Noticed that every single one was a smaller stem that came out below a main stem, and had no sign of fruit forming. Suckers? I'm not sure. But obviously the plant discarded them in times of stress, saving its resources for the fruiting branches.
