Fabric for frost protection

[TonyinCC]

This year at my location we suffered the first light frost in at least 7 years but very little damage. When I lived in the Charleston,SC area , I overwintered peppers and tomatoes by covering them with blankets and mulch. We had lows into the high teens Fahrenheit maybe once or twice a Winter, with several dips below 25. The tomatoes and peppers had damage but recovered. I think fabric can be very helpful to reduce the severity of cold damage,and completely protect up to some point. What if you could cover a full sized yet compact mango tree,say 10-12 feet by 10-12 feet fairly easily with one of these? Or double them up and combine with irrigation of the ground?

I would think a canvas parachute might work better than synthetic, has anyone tried using parachutes?
Personally I don't really need to worry much about cold damage where I am now, but I have a lot of experience in zone pushing when I lived in South Carolina and I thought old parachutes might be a good idea to at least consider. Maybe you could use a kerosene lantern or a few candles under the tree for a bit of additional heat that could get trapped under the parachute.

I purchased big frost cloths off Amazon, I think 50' long x 20x wide? Something like that. Also purchased some big tree bags that were 6' in diameter.

They certainly seemed to help, especially with lights strung up inside the bags or in the frost cloth but lots of work to install. Now my trees are all too big for the cloths so it's up to them to survive. Live or die!

The soil holds some heat and that is why larger tree overstory protects. Soil tends to lose heat by radiation into the night sky, cloudy nights stay warmer and even overhead trees accomplish this. If you use these frost cloths it would be a good idea to way oversize them and stake the edges out way past the tree to get the soil heat content benefit.
