Saw this on the news the other day.

Guess I got lower than 31°. I might need to get a thermometer.
One section of my yard got hit really hard. I will soon be on the search for cold-hardy fruit trees that can stand occasional flooding (thinking longan and white sapote?).
Didn't have enough time/frost cloth to cover Canistel, Barbados Cherries, and Suriname Cherries, and they took it like a champ. The small Peanut Butter Fruits got fried, but the big ones were unphased.
Almost lost our Redlands White Sapote when it flooded had to dig it out and pot it. Thankfully it flushed new growth after completely defoliating and looking toast for a few weeks.
