I've started picking the corn and despite my fears so far the cobs are all fully filled. They're a bit smaller than I'm used to but still a good size. The picking time for these only lasts a few days so I'll have to freeze some and give plenty away. The sweetness of corn just doesn't last in the fridge so I'll be pigging out.
The secret to growing sweet corn? Plenty of food and plenty of water. Once they have reached just under a meter tall they could live happily in a swamp. Also at this time mulch up high around the stalks with straw and manure and they'll send out more roots into this rich mix.
Merry Christmas!
