Silver queen corn is considered a sugar sweet corn by the University of Illinois and takes 92 days to mature for harvest. The long growing season means silver sweet corn needs planted as early in the growing season as possible. Sweet corn is wind pollinated, so must be planted close together for good ear development.
Choose a sunny location in the vegetable garden for planting silver queen corn. Make certain the tall corn stalks will not shade other vegetable plants that may need direct sunlight.
Till the soil to a depth of 8 to 10 inches. Remove any debris, rocks, and sticks from the soil. Break up any large clumps. Add one cup of fertilizer for every 10-foot-row you are planting. Rake the soil to a smooth surface.
Plant the silver queen corn seed 1 to 2 inches deep in warm soil. Space the kernels 6 to 8 inches apart in rows 3 feet apart. Plant in several short rows for better pollination. Cover the seed and water thoroughly.
Add a layer of mulch once the silver queen corn sprouts to keep weeds from growing. If you must weed, use shallow cultivation methods; the root system of sweet corn is close to the surface of the soil.
Water the silver queen corn weekly to provide 2 to 3 inches of water for quality crop production. Keep corn earworm damage to a minimum by twisting corn husks shut after silk develops and sealing with a small rubber band.
