All my tomatoes are in the hoophouse. They have been growing really well, ranging from 4-6 feet tall. Unfortunately they seem to be producing very few blossoms. We have a grand total of 2 tomatoes. It's been really hot in there all summer so for the past 2-3 weeks we haven't been shutting the door and windows. It's cooler in there now but still very few flowers.
Is there something I can do to promote flowering and eventual fruit production? I'm getting worried. It's been an epically bad growing season for us and if I can't even get a tomato harvest I may cry.
