How often does corn need pruning?
Rarely or never. Corn (Zea mays) does not need pruning. It is a monocot grass grown for its ears, and cutting or trimming the plant serves no horticultural purpose. Some growers remove suckers (tillers) at the base, though research shows sucker removal does not reliably increase yield and may slightly reduce it. Leave plants untouched.
