Frost dates in Garden Grove
A 32°F night is not recorded here: it happens in fewer than 1 year in 100, so median frost dates do not describe a typical year.
NOAA U.S. Climate Normals 1991-2020 for Santa Ana John Wayne Airport, 2.6 miles WNW of the city center. Low-lying and rural spots often frost later in spring and earlier in fall than airports and city centers. Garden Grove shares this station with Irvine, so the two cities have the same frost dates and planting calendar.
What to plant each month in Garden Grove
The main vegetable season is the cool half of the year: October through March is prime time for greens, roots, peas and cole crops, and many of them can be sown almost year-round because summers rarely get hot. Warm-season crops go in from about March or April through early summer, but 'May gray' and 'June gloom' keep soils cool, so heat lovers such as melons, peppers and eggplant ripen more slowly than inland. Nearly all rain falls between November and March, so summer crops depend entirely on irrigation. The months below follow the planting calendar for Southern California Coast from the Cooperative Extension sources listed.
