When is the Sweet Corn Ready?

It is a question I am often asked. The received wisdom is to pull back the shelves of the corn and press your thumb into the kernels. If they bleed white juice, they are ready. If I did this I would have spoiled almost all the cobs waiting for them to be ready. I have a much smarter plan. Inspect the cobs as normal. As soon as you see mouse damage, they are ready. The mice alway tackle the ripest cobs first. This year was abismal for Sweet corn. I had a block of twelve plants and only got fourteen cobs. Usually I get four cobs per plant!
