This is my experimental lettuce patch, in a photo taken early this morning. It was planted about 2 months ago in an old compost heap that was planted with tomatoes last summer. The location under a mesquite tree was too shady for tomatoes, so I tried lettuce, mizuna and Swiss chard. It's leggy and pale from being in the shade, but if it were in the sun it would be dead.
It's surprisingly not bitter and despite the high temperatures, it hasn't bolted. All I did was add a bit more dirt to the top of the heap, soak the seeds a few hours and plant them. It has a drip line, and is being watered 3 times a day for a few minutes each time.
