re: Young Citrus freeze protection

This is a good reference pub if you don’t have it Louisiana Home Citrus Production . Page 14 discusses winter/freezing protection.

Focus more on the blood orange and lemon as they are less cold tolerant than the satsuma. If you are 500 ft from a power source do you have a small generator you could borrow to run a light under the freeze cloth if required during the night?

Here is a quote from an article by Dan Gill (retired) horticulturist with the LSU AgCenter

Satsumas, for example, do not need protection until” the temperatures approach 20 degrees F. Lemons, limes, and oranges generally need to be protected when the temperature dips below 26 degrees F. However, theses trees may be killed or damaged at these temperatures if they are not sufficiently hardened with enough pre-conditioning cold temperatures to halt their growth. The length of time citrus trees are exposed to sub-freezing temperatures is also significant. Exposure to sub-freezing temperatures for more than 24 to 36 hours can be devastating. But, if the temperatures moderate to above freezing prior to this time, damage is usually light.
