Colder than normal

Friday night through Sunday temperatures will range from 8F to 1F.  Not good citrus weather.

Snow here will hopefully insulate the trees

Friday night through Sunday temperatures will range from 8F to 1F.  Not good citrus weather.

I'm in 7B, and we're looking at a week of lows at 10 F or lower, with a forecast low for the week of 4F (which is actually 7A weather). Highs won't break freezing.

In Vienna, Austria, we had a fortnight well below 0°C (32F) and a low of -11°C (12F). I don't see any damage on Yuzu, C. ichangensis, Citrumelo, Citrandarin...

What protection methods are you guys implementing?  I am in zone 6b/7a

[kumin]

No outdoor protection except allowing low growing Winter weeds to grow since October to prevent the February freeze/thaw frost heave cycles.
The Solar Greenhouse is maintained at a minimum temperature of 32°F. The high tunnels are maintained at at a low temperature of 15-18° F. Our outdoor low temperatures haven't risen to freezing in the past number of days and aren't expected to in the near future.

I'm using 2.8 oz frost nets, with a 7 mil white contractor demo bag outside that.

The trees I care most about (and which are closest to the house) also have a 40w lampshade under the bag.

frost+bag+lamp:
unknown citremon
   Madison's unknown variety: https://madisoncitrusnursery.com/products/citremon-citrus-tree
Prague citsuma
Thomasville citrangequat

frost+bag:
Morton citrange
US-942 citrange

nothing:
poncirus (species)

The lamps are set to go at 15 F and off at 25 F. They've been running quite a bit this last week or so.

How do you set them to turn on based on temps? That sounds slick!

Thermo cube. I was wrong on the temps: on at 20, off at 30.

I like the TC-2 specifically because it doesn't take it up above freezing, so it's not cycling between freeze/thaw.

There's also a TC-3 which cycles between 35 and 45 and a TC-1 (discontinued?) that cycles between 0 and 10. I'm too cold to try to hold above freezing (35F), so I settle for "won't kill the tree"

And now January and so far in February have been exceptionally warm.  Sometimes not even getting below freezing at night.  But next week is to be cold again, more like normal for this area.
