Before going away for a couple of weeks, my wife decided it was time to harvest all of the salad greens growing in this container. She's not particularly fond of arugula and I guess she wasn't crazy about the mizuna either which was probably a good thing because we had more than enough baby lettuce leaves for six people.
After a couple of weeks the lettuce in this container is growing again. I wasn't around to water it but I guess we got a bit of rain while we were away and the weather wasn't overly hot. The mizuna seemed to survive our absence as well and the arugula was starting to flower.
