Well... guess I provided a little too MUCH protection for some of my princess persimmons. I've been moving some of them into an unheated garage any time the temps were dropping below 25...
And now the ones I've been protecting are starting to bud. Guess I'll be doing the protection foxtrot with them for the next 60 days (give or take). Just shows you - it is very difficult to try to time Mother Nature.
[EDIT] I am editing this post because I went out to look and ALL of my princess persimmons are showing signs of budding. Very strange. Granted we had a very early winter this year with an abnormal deep freeze in November - but it's almost like they are saying "that's it - you had your 90 days of dormancy - time to wake up!" It was 13F here on Sunday AM![/EDIT]
