Hey all,
I planted Sweet Nugget F1 sweetcorn in modules on 17 April and they were planted out on 13 May and we got our first harvest on 28 July.
Charles, I know in your veg growing book the recommended spacing for sweetcorn is about 30cm. I kinda pushed mine to 15cm planting spacing instead as I have observed that the cornfield spacing in Germany were extremely close. (Plus I am running out of space!) In addition, I was thinking along the lines too that perhaps pollination would be a lot higher if the spacing was closer. I am happy to say the results have been fantastic. I planted with similar closer spacing the year before too and have given the same great results.
Just wanted to share my own personal experience and that perhaps we would be able to have more space for more plants and better pollination for sweetcorn plantings.
