How do you increase the yield of sweet corn?
How do you Fertilise sweet corn?
Apply three to four pounds of 10-10-10 fertilizer per 100 square feet. Fertilizer should be broadcast evenly and worked into the top two to three inches of soil prior to seeding. When corn is 12 inches tall it is a good idea to apply a sidedressing of fertilizer. This is especially important on light sandy soils.
How often should you water sweet corn?
Sweet corn needs ample water from germination to harvest, but the most critical period for water is about 2 weeks before silks form. Aim for 1 inch of water per week, and supplement natural rainfall with irrigation as needed.
