During germination you may need to keep them iout of sunlight. I start mine in the shade completely. They only need water to get started. You can start giving them some sun when the leaves appear.

the only thing that i can think of is the amount of sun that the beds are getting and the seeds need to be kept moist to germinate

Try covering the seeds with 4 or 5 layers of newspaper and watering the paper to keep them moist and dark.

try putting hessian bags over the area where the seeds are planted and keep moist . this will work for nearly all planted seeds and they will germinate a lot quicker than stated on the packet. YOU MUST KEEP THE HESSIAN WET/DAMP.

I have grown letuces for the first time and they are growing really well BUT each lettuce has 2 or 3 heads on it. There is the main one in the middle and they all either have another one or 2 heads growing off the side. they are beautiful and firm. IS THIS NORMAL, i have really good brown dirt in yard and added a bag of organic animal manure to soil 2 weeks before planting.

I have planted Cos lettuce for the past two years while they grow well they do not seen to develop a good heart. They are in good sun for 3/4 of the day in well draining soil. The soil was prepared with home compost and pea strall, any thoughts please

Cos lettuce don't develop a heart like eg iceberg lettuce. Just keep taking leaves from the outside as it continues to grow.

Hi Katy 9 weeks is a long time for them to only produce little bunches. For mild sweet flavour lettuce need to be grown fast - that is, plenty of water and plenty of available nutrients in the soil, including plenty of available nitrogen. Otherwise they can be quite bitter. Is it possible they got too dry or that the soil was not amended before they went in? Fortnightly feeding with something like worm tea can help if you're growing in containers or still building up your soil. Lettuce also tends to become bitter if it is going to seed, but if that's the problem you would be able to see the central flower stalk forming.

I am trying to identify which lettuces handle the heat better than others. We live in outback SA but we have plenty of water and I can erect shade, but I can't do much about the heat. Any suggestions would be appreciated.

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.
