Just over three weeks to Christmas so if you sow some lettuce seeds now you can keep them watered (either in pots or in the soil) so they’ll be established enough to survive without watering if you go away. Or you’ll have some lettuce to eat from your garden in the New Year. They grow quickly at this time of year and prefer some shade, particularly from the afternoon sun. I put four lettuce plants in a 30cm square and pick them a few leaves at a time. Splash out on some new varieties or try a packet of mesclun for the indecisive.
