Should we remove the suckers or sideshoots that form on sweet corn?
Some gardeners remove the suckers believing that the sideshoots reduce sweet corn yields by diverting energy from the main stalk and developing ear. Their removal, however, is not necessary and may actually reduce yields. Suckers develop on plants that are spaced too far apart. Space rows 2½ to 3 feet apart with an 8- to 12-inch spacing within the row. High nitrogen and abundant moisture will also promote sucker formation.
