Clare Wilson gives useful tips on growing sweetcorn (30 April, p 51). It is worth pointing out that each plant, though it might be up to 2 metres high, will usually yield only one ear of corn.
When I first started growing it, I thought I must be doing something wrong, so asked some farmers about it. They said that is just the way it is – one ear per plant. So you need to grow enough plants to allow for that.
