Planting and harvest dates in the chart are guidelines only; Microclimates vary as do annual weather patterns.
Planting and harvest dates are for a typical garden at 2000 ft, with planting dates adjusted by about one week for each 1000 ft above or below 2000 ft, earlier for lower elevations and later for higher.
Useful last frost dates in the guide are 1000 ft April 15, 2000 ft April 22, 3000 ft April 30, and 4000 ft May 7.
January-March seeds require cold frame in most areas.
The chart was originally developed for the Sacramento area by Dr. Robert F. Norris of University of California at Davis, adapted to foothill areas by UCCE Master Gardeners of El Dorado County, and modified for the Butte County foothill environment by UCCE Butte County Master Gardeners.
