hi, new here and new to an allotment. Just taken over half of an overgrown allotment so I have plenty of time to clear it and get it ready for planting. I am planning on three (or four?) separate areas to rotate annually - root crops, brassicas and beans/peas but, should I decide to have a go at growing sweetcorn, which group should it be planted with - or in a small plot on it own?
