Robust White Popcorn is a hybrid popcorn variety that allows you to grow movie theater-quality popcorn in your own backyard! While white popcorn varieties are traditionally not quite as productive as yellow varieties, Robust White provides that superior production with a delicate, heirloom flavor. Robust White produces plants that can grow up to 6' tall with strong stalks to withstand heavy rain and winds. Plants produce dense, 8" cobs that are loaded with beautiful white kernels. Once popped, the kernels are lightly and flaky with small hulls.

Robust White Popcorn should be planted in the spring after the last frost date. Corn can be grown throughout the warmer months up until fall, as long as time is permitted for harvest before the first frost. Succession planting is recommended with at least two plantings, one in early spring and one in late summer/early fall. Corn earworm 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 Robust Popcorn using a walk-behind planter like our Hoss Garden Seeder. Once plants emerge, thin plants to 6-12" depending on adequate irrigation. If drip irrigation is used, in-row spacing may be as close as 8". If water is scarce, the 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 the absence of kernels on the cobs. Allow the cobs to dry on the stalk and harvest when the kernels can be easily removed from the ear by simply pressing your thumb along the cob.
