Avalon Sweet Corn is a hybrid that is the gold standard for white sweet corn. Avalon is a TripleSweet variety, which means that it has 75% sugary-enhanced (se) kernels and 25% supersweet (sh2) kernels. As a result, it requires no isolation from other sweet corn varieties being grown nearby. TripleSweet varieties like Avalon have excellent holding and storage potential. This provides a longer harvest window in the field and also allows a longer window for processing/fresh eating. Avalon Sweet Corn has an excellent disease package and produces large, 8″ ears with 16 rows of kernels per ear.
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.
