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
