Zone 10 in October

Zone 10 in October: cool season greens make their big return

The largest wave of new starts since February

Cilantro, lettuce, spinach, arugula, radish, and bulb onion all open their fall window this month, alongside dill, chervil, mache, and calendula, giving zone 10 gardeners the widest fresh start of the second half of the year. Sow greens directly once daytime highs settle consistently below 85, typically reached by the back half of the month in most zone 10 locations.

Bulb onion sets go in shallow, just deep enough that the tip barely shows above the soil line, spaced about 4 to 5 inches apart, and this month's mild, lengthening cool season gives bulbs the steady months of growth they need before spring bolting begins.

A long last chance list closes out the warm crops for good

Bush bean, kale, chard, collards, mustard, cabbage, broccoli, cauliflower, and a dozen other fall crops planted back in September or earlier reach their last realistic planting window this month, since a start delayed past the middle of October leaves too little time to size up before growth slows through the milder but still shorter days ahead.

Root crops need the most attention to this deadline. Carrot runs closer to 10 weeks from seed to a full-size root, while beet finishes in around 55 days, nearly 3 weeks quicker; if the month is already slipping away, beet is the safer bet of the two. Wait too long on either and growth stalls before the root ever reaches a usable size.

Watch soil temperature more than the forecast

Most of this month's greens germinate best once a soil thermometer pushed 2 inches down reads somewhere in the mid 40s to mid 70s, and in zone 10 that number often trails the air by a week or two after the first cool morning shows up, so checking the dirt directly beats trusting how the weather simply feels.

What USDA hardiness zone am I in?+

Zone 10 is one band of the map, but planting time is set by your local frost dates, not the zone number. Enter your ZIP code in the free planner and it uses your actual frost dates, which can differ by weeks within a single zone.

Are these October planting dates exact?+

They are typical zone 10 windows. Two gardens in the same zone can be a week or two apart because of elevation and local climate, so treat these as a starting point and tune them to your ZIP code with the free planner.
