My lettuce grew! I planted some cheap seeds in late summer last year, and they actually grew! I had enough to share with the neighbor across the street. I just scattered the seeds, and didn't let them grow big, and harvested them as I thinned them. These photos were taken in Oct., but they got much bigger. I have a nice load of soil coming tomorrow, and will put in new lettuce seed for a spring crop. The 4 cinder block size bed is perfect for lettuce. So are those cinder block holes! My new cinder blocks have larger, square holes.
