*NOTE: Planting dates are approximate for Sonoma County; weather patterns, microclimate and other growing conditions must be considered when direct seeding and transplanting. “Days to maturity” is approximate and depends on the vegetable variety and your garden’s specific growing conditions. This information will facilitate planting dates that lead to successful production before the growing season ends.
C = cool season crops that grow best in soil temps of 60-65 degrees and air temps of 65-75 degrees.
D = seed is usually sown directly in the garden
T = crops are usually planted from transplants
D/T = seeds can be planted directly into soil or transplants can be used
When “D/T” or “T/D” is indicated, the first designation is the usual planting method for determining days to maturity. Use “Days to Maturity” for succession planning.
The actual number of days between planting and harvesting depends on the variety and your microclimate in that year. Vegetables planted in fall may take much longer to mature since the fall and winter growing season is so cool.
