I found this -Researching smudgepots. Don't seem to be the best solution for my 2022 fruit. Should I consider simply using box fans to keep the air moving. Whatch'all think?
Another option is to hang the trees with the old-fashioned Christmas lights, however these are getting harder to find. They need to be the big bulb type, the newer LED Christmas-tree lights won’t work since they’re cool burning and won’t give off sufficient heat. You can improve the protection by also covering with a blanket or tarp.
Another option is to turn a sprinkler on your trees just as the freeze begins, to coat them with ice. Although it seems counterintuitive, the ice will protect the tree because the temperature beneath the ice will not drop below 32 degrees. For this method to work you will need to keep the sprinkler on until the temperatures rise above freezing. If you plan to use this method of frost protection and the cold temperatures last for a while, monitor to ensure that you are not creating a flood somewhere else.
You may have noticed that some of the big orchards and vineyards use big fans to create air turbulence to protect trees from freezing. I do not like to recommend use of the fan for residential yards for a couple of reasons. First, most of you do not have a large enough fan to create enough air turbulence to be effective in protecting the tree.
