I learned my frost/freeze lesson here in Connecticut. I caught several times by the weather man missing the low. So, now any time they say it's going to be anything below 40 degrees I take precautions.
We have a weather station just 10 miles away. But, I have noticed at least a 5 degree difference in the temperature, between what is fore-casted on the weather channel, and our location.
They were forecasting temperatures of between 30 degrees and 35 degrees for this Friday, Saturday, and Sunday. We had to bring in all the figs, and place light bulbs at new pecan grafts.
Of the dozen or so variates we grow, Desert king potted has taken the cold worst then any other with small stems being killed from temperatures under 40 degrees .The one year rooted Gino's, seems to hate the cool/cold weather a lot. The leaves get saggy.
