Description

Primus Sweet Corn is a hybrid, bicolor, TripleSweet corn known for its exceptional taste and disease-resistance. Primus is a TripleSweet variety, meaning it contains a combination of sugary-enhanced (se) and supersweet (sh2) kernels. This combination of 56% se kernels and 44% sh2 kernels means Primus requires no isolation from other sweet corn varieties. Vigorous plants grow to 6.5' tall and produce 8.5" ears that set at 24" high on the stalks. Because it has more sugar and less starch than traditional sweet corn varieties, Primus holds well in the field and once harvested. This provides a longer harvest window and allows more time between harvesting and processing/fresh eating.

Growing Information

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.
