The good news in my San Francisco backyard is that the weather is mild, with no freezes. The bad news is it faces North, so everything grows in slow motion during the winter. My broccoli is pretty anemic, but chard does great, and so do greens and snow peas. Even though it’s barely rained all fall and winter, it’s so shady I really only water every couple of weeks.
Here’s tip: plant Miner’s lettuce. It’s a native plant that spreads like crazy over the winter and it’s really tasty. During the rest of the year it disappears. Another tip: plant pots of lettuces. I like spinach, arugula and mustard greens. They require almost no care and anytime you want a salad, it’s right there.
Another bonus to the winter greens, you’ll make some new friends.
