Zone 10

Zone 10 has the longest growing season with the mildest winters and long summers.

Frost dates are short, with a last frost date of mid to late January and a first frost date of mid to late December means a frost-free growing season from late January to early December. These dates are general guidelines, so watch the weather forecasts before planting.

A very long growing season with an average low temperature of 35°F means almost all vegetables can be grown with some summer shade for heat protection.

Scroll down to see the vegetable planting guide. The orange color shows when to start seedlings indoors, the yellow is times to transplant or direct sow and the green is harvest dates.
