My tomato plants , mortgage lifter and better boy arent producing fruit. I will see lots of flowers and then they are gone next day. Have kept them watered , epsom salt, shaken and still nothing. Is it possible grasshoppers are eating the flowers. I live ln utah and its dry, been hot. I cant even get zucchini to grow fruit.

when you say there are no flowers do you mean literally no flowers? have they dropped off or disappeared totally? If they have dropped off its possibly that the flowers are not being pollinated. take a paint brush or cotton bud and carefully coat the tip with pollen and then carefully rub the pollen onto the centre of a neighbouring flower. keep the humidity up and hopefully that will cause fruit to set.
if they are totally missing it could be crickets/grass hoppers, mice even.
