Jan 5, 2016 = Day 62. Began harvesting lower leaves for use in salads.
I am continuing to harvest lower leaves for salads several times a week. The plants are starting to get tall, they will probably bolt within the next few weeks, so I need to finish up my harvests soon or the leaves may get bitter.
