“ Sweet corn is very easy to look after once they have germinated successfully. They appreciate a good watering especially when they are in flower. ”

They also appreciate being fed at fortnightly intervals with fertilizers designed for tomatoes (i.e. not too high in nitrogen, but high in potassium).If the plants are at all exposed to wind, it helps greatly to pile up earth around the base of the stems - this will encourage more supporting roots to grow just below ground level.

Cultivate shallowly to control weeds. Chemical herbicides are not recommended for home gardens. Although corn is a warm-weather crop, lack of water at critical periods can seriously reduce quality and yield. If rainfalls ideficient, irrigate thoroughly during emergence of the tassels, silking and maturation of the ears.
Hot, droughty conditions during pollination result in missing kernels, small ears and poor development of the tips of the ears. Side-dress nitrogen fertilizer when the plants are 12 to 18 inches tall.
Some sweet corn varieties produce more side shoots than others. Removing these side shoots is time consuming and does not improve yields.
