Well, we've had a few more cold snaps (cold for Phoenix) over the past 10 days. This past weekend was down to 27, and since then we've had a few days of 30 degrees, and tonight is due to be 29. I've been successful so far protecting them, but it's much harder now that they're substantially bigger plants. Some have grown taller than the 6' wall behind them, so I've had to get creative.
Wish me continued good luck!
