well, farmer fred says to let them be. my grandpa, told me to get rid of them. my personal experience leans me towards grandpas advice. what am i talking about? its whether to remove tomato flowers when the plants still havent been planted - i.e. still in pots; getting trucked into the garage nightly and out of the garage morningly (is that a word?).
pa told me the to take them off as it will probably stunt the tomato plants growth - let the plants focus on the roots. a few years ago, i missed a flower on a plant and it was a tomato about the size of a quarter before i saw it. i decided to let it go, that particular plant didnt do much until that tomato was harvested - after which it zoomed up in height and still got a decent crop from it.
what can others glean from this? well, my experience relates to only 1 plant, thats about as small of a sample as one can get - and with a sample population of 1 - the bell-curve is bit whacky - so your milage may vary. but i will continue to pluck those puppies, until the plants actually hit the dirt. sorry fred, but pa wins out on this one.
