Murray Goff will watch the thermometer and the plants in his nursery closely for the next two days.
"We probably do more weather watching and praying than anybody in the world," he said.
In two weeks, the nursery is scheduled to ship out 40 truckloads of flowers, shrubs and other spring foliage. Without the right precautions, the cold snap could spell doom.
"As long as we can stay 20 or above we are fine."
Murray's nursery covers more than 45 acres and is too large to cover with a protective cloth. Since Murray can't hide from the cold, he uses water as a protective barrier for the plant's roots.
"The outside of your bucket freezes, then the inside doesn't freeze solid, and you pick up enough moisture inside to keep that plant alive."
The wind is also a concern. A strong gust can knock down hundreds of plants at one time, making them much harder to water. Nursery crews are trying to prevent that by pushing all the plants close together.
"Just like dominos, if one falls then it will knock another one and just keep going."
