Starting next week, a polar vortex will most likely cause temperatures across the eastern half of the U.S. to be below average throughout most of January. Cover your plants! Even temps in Louisiana are dropping below freezing multiple nights in a row. I recently put up the Vego Garden Cover System and the mesh covers are working great! They also protect against the squirrels! #garden #gardening #polarvortex #louisiana #horticulture #plants #winter
