You bet! Lettuce doesn't like the temperature to be above 80 degrees. Mine is bolting and bitter now too ( June in 7b)

Lettuce won't germinate if the soil temperature is too high, but if you can start them somewhere shady they might do ok.

Yes you can, but depending on how hot it gets where you are, you should choose a heat-tolerant variety or it will bolt too quickly. I recommend the red varieties of summer crisp Batavian lettuce. You should be able to get them at Swallowtail Gardens online if they haven't sold out for the season.

I grew romaine last year in the Phoenix Valley (9B). I think I waited until December to sow the seeds. We got a really nice crop of it... but last winter it seemed to last much longer than normal, it was still very chilly in Feb. last year (low 60's), when generally we get into the mid 70's then. You could try starting indoors.

Planting lettuce

Planting lettuce indoors and will transplant outdoors after last frost in May. Keeping some of the plants indoors and will move to larger containers before the roots bind up. My starting mix will need added organic fertilizer after the real leaves are put on and grow light intensity needs to be increased somewhat for indoor food production. If this experiment works, I may continue growing through next winter. As for my outdoor lettuce, last summer I managed to get several cuttings. This year I will be planting on the north side of pole beans so that when the beans are tall and the summer heat comes on, my hope is the shade will increase my lettuce yields for a longer period of time .
