Why is it that so many of vegetable plants go to seed before 'hearting'. Mainly lettuce?

Hi John, not sure if your question is about your garden, or just seeding in general. I had total failure with my lettuce this year. I planted in November, and the Sydney summer was just too hot. In some areas classed as temperate climate you can plant all year, but this guide can't fit everyone. Where I live is generally 6 degrees hotter than Sydney CBD throughout summer, so trying lettuce at that time of year was stupid. Lesson learned. Regarding bolt in general, I think it's really just that plants will do anything to survive. I'm no botanist, so this is all my opinion only. If the conditions are perfect, the plant has the energy and nourishment to produce a harvest. As conditions move further away from ideal, the plants behaviour becomes less about producing a large crop (showing off), and more about survival. When conditions are untenable, the plant will abandon the crop, and put all available energy into producing seeds to try again next year. That's bolt as I understand it, I'm more than happy to be corrected.

Lettuces like cooler weather. Varieties like Iceberg, Imperial 847, Imperial Triumph will bolt to seed readily.Great Lakes, Penn Lake, Yatesdaale will tolerate warmer conditions but are a coarser leafed lettuce.

I left my cos lettuce to seed last season in our raised garden bed. The new plants are now growing beautifully, but they are all quite bitter. Even the baby plants. They are getting plenty of water, being winter time! Any ideas as to why this may be and what I can do about it?

Usually if it's too hot lettuce can get bitter but I think it may have more to do with the soil quality, and/or Ph. I would look into the Ph and then the soil nutrient content.

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.
