I have planted some fancy mixed salad plants in a pot, 2 of the 6 died, but the other 4 look healthy but the leaves feel quite soggy rather than crisp, any reason for this? also when i water them the seem to flop even more and are better the next day. Do i just harvest the outside leaves slowly and will it re-grow?

I am new to vegetable gardening. I have noticed thousands of red mites running around in the soil around my seedlings. They don't seem to be on the seedlings but I wonder if they may cause a problem. Any idea whether I need to control these mites and, if so, how?

I have planted several perpetual lettuce but half of them are going to seed less than 2 weeks after we picked our first leaves. I understood with perpetual lettuce that we just harvested the lowest leaves. I assume even perpetual lettuce will seed eventually but is there a way I can prolong the life to more than the few weeks? Thank you

Why is my cos lettuce going to seed? there being goin really good and all of sudden bolted and gone to seed

Hi Lance, Unless you are able to water Lettuce everyday (twice a day in a pot) during the warmer months then it will bolt. Lettuce is a much happier autumn - spring crop

Cos are definitely a cool weather variety but otherwise it depends on your climate whether lettuce will grow in the Summer.

Hi Ann, I had birds eating my lettuces too, I rigged up some string and silver plastic plates (or cans do) in and around the lettuces, it has a scarecrow affect and keeps the birds away. Be sure it isn't a possum as I have had them eat my lettuce too! Hi Lance, Lettuce has gone to seed as that is their main aim in life. In the summer months it is best to protect the lettuce from the sun and water regularly. Heat and lack of water causes the plant to stress and therefore it seeds as it thinks it might die. Some varieties of lettuce also just have a short life span, so I would suggest choosing varieties such as "four seasons".

I grow lettuce through the winter frosts. They thrive under agri-fleece material, and survive uncovered so long as the ground doesn't freeze. A chinese cos-style lettuce 'Glenda White' that I got from seed savers years ago does particularly well through winter.
