If you grow the loose leaf types you will have better success against frost. I have frost proofed my 2 permanent beds of six different lettuce by growing them in wicking beds and aquaponics as the whole bed keeps itself protected by being a thermal mass during the night absorbing heat from direct sun in the day. Otherwise throw some heavy duty clear plastic over them last thing before the sun goes down and keep your mulch nice and thick. That will help maintain a warmer temperature during the night.

I want to know if you can grow lettuce but only look after it about 3 times a week. Would it still be okay and not turn bitter.

If growing in a raised bed with a timed dripper system, no problem. If growing in a wicking bed even better! Looking at it 3 times a week might take some extra mulch if growing in a normal bed with manual watering but should be still doable.

Are lettuce susceptible to frost. We live in an area where most days are mild but it can get to -3 in July August

A certain something is added to the fertilizer while iceberg lettuce are growing to achieve this round firm head.

I planned lots of lettuce (cos and ornamental/frilly? Red and green) early December and rhry have all bolted or not grown much. It is hot here in Perth. I tried snipping off outer leaves early but they were very bitter. Am i wasting my time growing lettuce in summer in Perth? Thank you. Debbie
