I can’t seem to grow Iceberg lettuce. I have tried and tried and tried but every time I seem to fail. My failures have been varied; from the plants simply dying, to going slimey, bolting too early and failing to heart. The below is typical of my failure to heart results.
The leaves seem to be the right sort of shape – they just aren’t growing into hearts; they are spiralling outwards instead. I guess they might be bolting but they don’t seem to have a main flower bit as yet.
What is the secret to growing this vegetable? I’m very keen to wrap some spring rolls and make San Choi Bao so any help would be gratefully appreciated.
Maybe I’m not giving them enough sun?
