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

Sounds like they're having water and heat problems Debbie. Pretty tough to deal with in the Perth heat I imagine. You could always collect the seed and try another crop at a cooler time.

Most clear plastic is considered direct sunlight - unless there are special filters in the plastic. That is to say, if the only thing between your lettuce and the sun is regular clear plastic, you should be fine. As and FYI there are multiple categories: 1. Direct sunlight - some plants require direct sunlight on their leaves 2. BRIGHT shade; for example when I lived in a Condo, my balcony had no direct sunlight, but because the buildings beside my building had huge glass windows I had VERY bright shade and could grow most full sun potted plants. This also applies to living near the water, where the sun gets reflected-- MOST full sun plants are fine with REFLECTED light but not all. This could also be a a very sunny field, with shade cast from one building, chances are good that would be very bright shade 3. Sun/Shade with all its variations 4. Light shade and 5. Deep shade like the middle of a dense forest. I see no reason why you could not grow SOME of your veggies in the bright shade. I find that many plants labelled full sun, are not. For example: strawberries are generally labelled full sun. However, strawberries TEND to grow naturally in the shade of other plants: woodland or forest floor, in meadows shaded by other plants. I've noticed that any of my strawberries that get full sun tend to have burnt leaves, and the best yielding strawberry plants are in a cool predominately shady areas. I suspect that planting your plants that tend to bolt in a cooler shadier area would be very helpful. I've even grown cherry tomatoes in very bright shade with great success.
