Hi, I'm new at this gardening lark and loving it. Learning from local and very helpful small garden center (But can only ask so much without becoming a pest), books and the web. Came across this forum that looks friendly and helpful. My sweetcorn, grown in greenhouse from seed and now in veg plot 2-3ft high and looking healthy has side shoots attached to the base of the plants that look like a second and third in two cases sweetcorn growing. Should I remove these? I don't want to destroy what are healthy plants if this is not necessary. Any advice appreciated.
