Why does my lettuce produce new leaves on top but the bottom leaves turn yellow and wilts? Looks like it is growing well, since new leave appear all the time, but the bottom leaves then wilts... What should I do, or what am I doing wrong?

Your lettuce is probably getting too much sun or its too dry... try putting them in a more shady spot and watering plenty?

Establishing a new veggie garden in full sun in frosty rural Northern Tablelands NSW. Thinking a wire fence to keep out rabbits, roos etc. Any suggestions for a deciduous climber to grow on the fence running north-south to protect my veggie garden from the western sun in summer but warm it up in winter. Winter nights can get down to -15°C. Thank you.

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

As it says here read the packet for when to plant. Generally the open (not heading) type are better for summer, butter head or butter crunch etc. Try and provide some shade during the day, in the sun in the morning in the shade in the afternoon or shade cloth frame. .
