Cedar Garden Bed Oil can be used with all Gronomics Cedar Products. It's non-toxic and provides a beautiful food safe finish that is very easy to apply. Oil applications should be administered when air and wind temperatures are between 50-90 degrees Fahrenheit. Avoid applying in direct sunlight for best results. 1 quart covers approximately 100-150 sq. ft., which is equivalent to 2 coats for a medium to large size garden bed.
