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".

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.

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

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 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?

My COS lettuce is booming - growing really thick really quick with lots of leaves. much better than my attempt to grow it in summer, where it shot up had a tall stem, seeded and few leaves.

Like Marcel....My iceberg lettuce doesn't seem to get a firm 'heart' just a bunch of loose leaves. I followed the seed packet and planting instructions.

To increase the levels of Molybdenum (Mo, also called Molly) in your soils -- wood ash (from a fireplace, firepit, or barbeque) can be incorporated into the soil. Alternatively, Banana peels are an excellent source of Moly. Animal manure tends to (grass/grain/vegetable feeders) tend to have a decent amount of Moly in their manure. If all of these are out of reach, perhaps try incorporating wood chips/bark mulch in your garden. You can make bark chip paths, use the paths, then the following year when the chips are broken down mix them into the soil. OR -- just mix the wood chips (bark, mulch, whatever) directly into the soil. As the wood is breaking down it takes a lot of nitrogen. I would expect to find Moly in leaf mulch - but have not found any reliable sources that have stated this as a fact. If you choose to use chemical forms of Moly remember that this is a TRACE element - VERY little is needed and over application can result in a OTHER problems. Staying organic almost guarantees you will not over apply. If you live in an area where wood burning stoves and fireplaces where common for heating (pre- electric fireplaces and stoves) - and you know people old enough to have been around when wood ash was common in the garden (there was no place else to put it) - they can tell you how amazing the gardens where back then.
