Isn't this lettuce beautiful? It is certified organic and available at the shop in six different varieties. I haven't had much time to get my home garden going. I am going to plant an entire whiskey barrel (1 out of 3) outside my kitchen door with lettuce. Lettuce can and should be harvested as frequently as possible. When it is @ 5 inches tall or so cut it leaving about an inch or so to regrow. After you harvest, water the bed well ( or container ), and feed lightly with liquid fish fertilizer. The cut lettuce crowns will regrow for another harvest.
