With our great climate, not only can we wear down jackets in July, we can grow lettuce year-round.
Lettuce doesn’t like summer heat making it perfect for San Francisco’s fog-shrouded summers. Grow some now!
Lettuce is easy to grow and ready to harvest in a couple of months–the perfect plant for both the beginner and those with short attention spans. And, lettuce roots are relatively short making it great for container gardening, another plus for San Franciscans who are squeezing our gardens onto fire escapes and rooftops.
The most common categories of lettuce are romaine, crisphead, whose best-known variety is iceberg, butterhead, with its large, loose leaves (Boston and Bibb are its most popular varieties), and leaf lettuce, including green-leaf and red-leaf lettuce. All are equally easy to grow in our cool climate. But take note that snails and slugs don’t seem to care too much for red leaf lettuces.
For beginners, start with seeds if you’re feeling bold, if not get a headstart and buy a six-pack of lettuces at your local nursery.
