    Collapsing lettuce

    I have two cold frames which are kept open all the time now. both contain lettuce.
    In one of them I have had lettuce suddenly collapsing one at a time. Cant find any sign of beasts and the base of the lettuce looks as if it is rotting. No sign of botrytis either. They are kept a bit on the dry side to avoid rot.

    Any suggestions please?

      Don't think so, the tops are off all the time. The lettuces seem to go down one at a time as if some critter does for one and then moves on to the next, but I can't find the beast! Also it is only happening at one end of one frame. Mystery!

        Dig them up and transplant them out into a bed if they're not too big for that.

          Cant do that they are just about eating size and they collapse over night.

            How dry is "a bit on the dry side"?

            I find the most common cause of plants suddenly collapsing is shortage of water, especially if the weather is hot too. I expect it's getting quite hot now where you are.

            Lettuces in particular can't tolerate drought. But if you catch them soon enough and water them and leave them in a cool place for a while they'll usually recover, if that is the problem.

              They are damp and I don't think it's a water problem. The base of the plant has rotted but I can't make out if there was insect damage first. They are also collapsing one at a time the others look fine
