Hi Bill, >> Have several questions. First, is this accurate? Second, if yes, is there a minimum period of time they need to below 50 before the blossoms are damaged, or is it if it occurs for any period of time.<< The premis is usually accurate. Change it to read "fairly accurate." You probably didn't destroy the blossoms but there will not be fruit set until there is a night that stays above 50 Deg all night. The blossoms will cling for a few days and MAY still be pollinated if warmer weather prevails. Mother Nature has her whims and won't always pay attention to the "techie freaks" who try to set things in concrete. Remember, if the first truss won't pollinate the second one may very well do so. Do you have a kerosene heater or such to boost thngs along ? Once pollination has occurred, the plants often will hold fruit down to the mid thirties for short periods. Stupice does have a bit more lattitude than most. Good gardening, Chuck Wyatt
