Old blankets and sheets are a great way to protect plants from frost. The blanket will help insulate tender plants and keep them alive during a frosty night.

What can I use if I don't have frost cloth?

Why do farmers spray water on plants before an overnight freeze?

The idea of using irrigation to help prevent frost is that the water that is sprayed in the fields freezes and releases heat to the air as the liquid water changes to ice. The goal is to keep the air temperature in the area at 32 F by adding heat in this process.

What is the difference between a frost and a freeze?

The National Weather Service (NWS) says that a frost can form when the temperature falls below 36 degrees Fahrenheit, with it being more than likely in rural areas. Frost becomes more widespread when the temperature falls below 32 degrees. This is where freeze can occur.
