Container gardening in the coastal Bay Area

Choose the local Bay Area climate calendar, then check sunlight on the actual patio. Mild temperatures do not give every neighborhood the same sowing season.

Which calendar fits?

UC Master Gardeners of San Mateo and San Francisco counties provide hot, sunny and foggy calendars. Examples place Redwood City and Atherton in the hot group, San Mateo and Foster City in the sunny group, and San Francisco, Pacifica and Half Moon Bay in the foggy group. Read the full location descriptions.

These are categories within that local resource, not USDA hardiness zones or measurements of direct sun on a balcony. A shaded patio still needs a light check.

Choose the crop and method together

Decide whether you will direct-sow or buy transplants, then match that method to the calendar. A transplant recommendation does not establish a seed-sowing deadline.

The lettuce, spinach and radish guides explain growing setup. The cool-season sowing article connects that setup to the local planting decision.

Inspect the winter patio

Observe building and railing shade while the sun is low. Keep space for watering and harvest. Summer fog and winter building shade are different constraints.

Sort pots into rain-exposed and sheltered groups. A container beneath an eave may need water while its neighbor remains wet. Check the mix rather than switching every pot to one winter schedule.

Where this hub applies

Coverage begins in mild coastal and bayside lowlands. Higher hills, warmer inland valleys and Southern California need their own county guidance. Follow cold forecasts even within this coverage.

Use the sowing article for a new crop and winter watering as rain patterns change. A California coastal address alone is not enough reason to borrow a calendar.
