It is by far the hardiest lettuce I know, but any light green oakleaf variety does well in my garden. In the Piedmont, lettuce is intermediate in season and probably is best as a late spring and early fall crop.

Romaine has requirements similar to head lettuce, except it can stand more heat. Butterhead and leaf types can stand even more heat and have a longer season of production.

Lettuce grows best in a temperature range of about 45 to 75 F. In weather hotter than this, the leaves begin to get bitter to the taste. When leaf lettuce bolts—begins to send up its flower shoots—it's a signal that the production of edible lettuce is done for the season.

The premise of The Produce Contamination Problem is that when human pathogen contamination of fresh produce occurs, it is extremely difficult to reduce pathogen levels sufficiently to assure microbiological safety with the currently available technologies.

A wiser strategy would be to avoid crop production conditions that result in microbial.
