Hi Chris,
>>Perhaps you could let us know the latitude, altitude and current temperature range of your ivy flowers as well as the first date you saw the blossoms open.
I am not sure of my precise coordinates (Smithtown, NY) but I am 1.5 hours almost directly east of NYC. My approx. location is 40.45N and 73.85W. Our daytime temps are in the 70's and 80's F and nighttime temps in the 50's and 60's F.
I saw the bees working the ivy over the weekend. Judging by the % of the open flowers (about 25% last weekend), the bloom probably started in mid-September.
I hope this is helpful. It's been another mostly dry August and September. [Do dry conditions trigger ivy to secrete better?] I am just glad there is something for the bees to work.
Waldemar
