Maz, if you wait until the leaves of the plant turn yellow, you will be very disappointed with the flavour and eating quality of the sweetcorn. Just pull back the husk at the top to look at the kernels. It will be obvious when they are ready, they will be a lovely yellow, and full of milky liquid.
My OH and I had some for lunch yesterday, cooked in the microwave for 5 minutes for three large cobs.
