Frequently Asked Questions


What’s the most common disease or pest problem on sweet corn (Zea mays var. saccharata), and how do I control it?
Watch for corn earworm and fall armyworm, which chew into developing silks and bore into ears. Apply a targeted treatment when silks are just starting to brown (use a Bt-based product labeled for earworm/armyworm) and remove any heavily damaged ears to reduce larvae buildup. If you see common rust (orange pustules on leaves), improve airflow between rows and avoid overhead watering to slow spread.
How often should I water sweet corn during the main growing phase to keep ears developing well?
From about knee-high through tasseling and ear fill, keep soil evenly moist with about 1–1.5 inches of water per week, increasing to maintain moisture during hot, dry spells. Water deeply so the top 6–8 inches stay damp—shallow watering can reduce root depth and lead to poor ear fill. Stop letting the soil swing dry-to-wet; consistent moisture during silking is critical for good kernel development.
How can I tell when my sweet corn (65 days, Zea mays var. saccharata) is ready to harvest?
Harvest when the ear silks have browned and dried, and about 18–24 days after the first silks appear. Kernels should be plump and release a milky fluid when pierced with a fingernail; if the liquid is watery, it needs a bit more time, and if it’s doughy, it’s likely past peak sweetness. For best flavor, pick early in the morning and refrigerate right away.

Sunlit kernels arrive in a rush—Howling Mob sweet corn fills out with a vivid, warm golden-yellow sheen and a tender, milky bite that feels almost silk-smooth. The ears are well-filled and impressively uniform at about 7 inches, with kernels that burst with bright, sweet flavor and a clean, juicy texture. Grow Howling Mob for peak-fresh enjoyment and for showy, crowd-pleasing corn-on-the-cob moments, plus its naturally sweet character shines in salads, salsas, and creamy sauces alike.

Sowing Tips

Transplant Conditions

Wait until soil reaches 55°F and nights stay above 28°F before moving outdoors.

Expert Note

For the most tender, sweet ears, keep soil evenly moist after tasseling and plant in blocks (at least 4 rows) for better pollination.
