Similarly one may ask, how do I protect my papaya tree from frost?

Cold Protection During cold weather, even light frosts, protect your papaya plant with a burlap-covered frame. To add extra warmth, place an incandescent lamp inside the frame or string Christmas lights in the branches. Avoid cool LED Christmas lights, which do not provide the needed warmth for the plant.

Similarly, at what temperature does citrus fruit freeze? Citrus fruits easily freeze at 26 to 28 degrees when these temperatures occur for several hours. A longer duration of freezing temperatures is required to freeze grapefruit compared to sweet oranges.

Hereof, why do farmers spray water on oranges to protect them from frost?

So, when a freeze is forecast for a citrus farm, the farmers often spray the trees with water. When the temperature drops, this water freezes and releases heat to its environment, some of which is the still-ripening fruit. So, paradoxically, causing ice to form on the fruit saves it from freezing.

How do you protect a grapefruit tree from frost?

Cover the trunks from the ground level up to the main branches. Keep the ground around the trees as clean and as free from mulch, weeds, and ground cover as possible. Bare, moist soil radiates more heat than soil blanketed with mulch or ground cover, and this radiated heat helps protect trees from frost.
