I have always grown my lettuce in the ground. I buy a mix from Pinetree Gardens, and cut it way before the head stage. The last few years, we have harvested very little because it is to difficult for us.
I have a nice deck with a southern exposure, with a screen porch that could block late afternoon sun. I am thinking of getting some long, narrow planter boxes to line the deck so that I can plant the lettuce in them.
This would put the lettuce up at least a foot - maybe more, making harvesting and caring for it so much easier - plus no dragging the hose around the house to water.
Is there anything special I need to look for in containers or potting medium? I thought I would just mix potting soil with my compost. Put layer of rock in the bottom over top some old window screen to keep dirt from going out the drainage holes.
I have grown flowers in containers, but never lettuce.
Might want to try some turnips, radishes, carrots too...
Thanks
