When they have 6-8 new leaves. Keep them protected from the sun for a couple of days. Plant in the late afternoon.

Can it get too hot in May for lettuce, mine seems to have turned bitter and is bolting

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

why is it advised to "Avoid growing close to: Parsley, Celery"?

Some plants react with others or problems in the soil.

Will it be to late to sow Lettuce seed in Johannesburg region in February. Have a well protected area from early cold and can provide sufficient water when rainfall reduces from March.

Try it.

Hi, when you say lettuce needs sunlight, does that have to be direct sunlight or can it be under a patio shelter that has a clear plastic roof? My veggie patch is in full sun, a very hot spot and they always bolt quickly, so I would like to try them out of direct sun, but in a bright area and easy access for keeping on top of the watering. Do you think this would still work? Thanks.
