Did you see what ‘The Millennial Gardener’ did with bricks in this video, in this video he also goes in to detail how he uses his agricultural plant covers https://youtu.be/O5pc_GYjyKI?si=o_3j8hlwpTnQeR8U&t=511
and these are the plant covers he uses for his citrus and his avocado Amazon.com : Agfabric Plant Covers Freeze Protection 120"x120" 1.5oz Garden Plant Cover Plant Frost Protection Covers Winter Frost Pests Protection,White : Patio, Lawn & Garden

Wondering how well those heat techniques would work in the upcoming cold weather.

Mine have handled down to 11 degrees with the frost cloth/heat blanket/light method and highs below freezing for three days. Even the most delicate one, the Persian Lime on its own roots, pulled through with just a little bark splitting. If this were earlier in the year, like the Christmas freeze of two years ago, it would be a problem. But the plants are hardened off now.
This is also where the microclimate becomes important. Four of mine are planted in a pretty sheltered place at the bottom of a slope. It seems like the cold should gather there, but actually farther up the slope always has frost while at the bottom, for some reason that I can’t explain, it does not. All the snow from the last storm has already melted around the citrus, but farther up the hill it has not.
But 6 degrees is pretty cold, so this is where the gamble comes. Mine have never handled that low but I actually think that they could, given the right factors, in a year or two. It’s boils down to your risk appetite for zone pushing.

That is what I am worried about, here can actually go down to 3 degrees, that is why a part of me fears the idea of planting in the ground. Although a part of me knows that if I protect better than ‘The Millennial Gardener’ does, then that temperature should not be too much. Although how much better would I need! What I have in mind for beyond ‘The Millennial Gardener’ is a thick layer of dark gray gravel as mulch, two brick towers instead of one, water sprinklers running inside each agricultural plant cover (which is a method that Stan McKenzie uses), while still using lights, and using a pickle barrel like ‘The Millennial Gardener’ does.

How cold hardy are the blossoms and young fruit? My min winter temps are not the problem. I’m must concerned about blossoms, just as I am with my apricots.
