Silver Queen Sweet Corn is the standard by which all other white sweet corn varieties are measured. This standard, old-fashioned sweet corn variety has been a favorite by many for decades. Because it is a standard (su) variety, it matures slightly later than (se) or supersweet varieties. Silver Queen plants grow 8-9′ tall and produce ears that are 8-9″ long. Ears are filled with shiny, white kernels that taste like summertime. Silver Queen Sweet Corn is a great variety for fresh eating and will store in cold-storage for 3-5 days before becoming starchy. It is also a favorite by many for creaming and freezing in bags to ensure sweet corn year round.
Sweet corn should be planted in the spring after the last frost date. Sweet corn can be grown throughout the warmer months up until fall, as long as time is permitted for harvest before first frost. Succession planting is recommended with at least two plantings, one in early spring and one in late summer/early fall. Corn ear worm pressure will be greater in the warmer months, but this can be alleviated by applying spinosad to silks and tassels once they appear.
We recommend planting sweet corn using a walk-behind planter like our Hoss Garden Seeder. Once plants emerge, thin plants to 6-8″ depending on adequate irrigation. If drip irrigation is used, in-row spacing may be as close as 6″. If water is scarce, a wider in-row spacing will be necessary. For pollination purposes, corn should be planted in a square plot with rows on 30-36″ spacing. Planting a few long rows will result in poor germination and absence of kernels on the cobs.
