The mention of a freeze tonight sent this household into plant protection overdrive. Was it yesterday that it was 75°? Not so today. A bright sunny day but with a howling wind which precedes the cold front expected tonight. In the hill country they are predicting it will drop into the 20s and we are sited right on the very edge. I expect the temperature to drop below 32°
Some plants merit special treatment. The calamondin orange, loaded with ripening fruit. The only one of my citrus to produce fruit this year because of you know what.
The sticks of fire Euphorbia was already showing signs of the temperature change. All the new growth that has not had time to make chlorophyll is bright yellow and beginning to turn red. It can come in the house for the winter.
The greenhouse is the winter resting place for all kinds of cactus and succulents. Those that can withstand colder temperatures go in there.
The roof is partially covered by the cross vine which offers some protection and then the edges of the benches are lined with milk, wine and water bottles filled with water. You'd be surprised how much that water heats up on a sunny day. The thermal mass help to keep things above freezing. There is a small back-up heater which will come on if it gets too cold.
More tender plants go in the potting shed which is insulated. The huernias all hang on the wall and those that like a little more sun go on the bench in the west-facing window.
The citrus are on the floor. Then there is the garage. The truck will spend the winter outside.
And a few cactus in the house.
Alas, the Agave desmettiana chose the wrong time to send up a flower. I have never seen a successful flowering yet and the only other one that tried to flower did so at the same time of year and the frost got before the flowers opened. This plant was so severely damaged in the spring hail but I just hadn't dealt with it. It was not going to go out quietly. Fingers crossed that it will survive the night.
Hang in there peas, broccoli, pak choi, arugula, radish, onions, carrots, and all other plants spending this cold night outside.
