I dutifully put in my tomato plants in early June, after the threat of frost was over, and they have been growing well over the past few months as the weather continued to warm up.
I live in Northwest Montana at about 3,500 feet if that matters.
Over the past 3 weeks the weather has been hot, in the low 90’s, and there is a lot of fruit on the vines. Unfortunately all of that fruit is green and I see no evidence of ripening.
The weather is starting to cool off now, and the highs will drop from the 80’s to the 70’s (and perhaps the 60’s) over the next few weeks. The evenings are starting to cool off dramatically too.
So what can I do to force the tomatoes? Last year I brought them into the house about this time and they all became rotten.
