Frequently Asked Questions

What’s the most common pest or disease issue for sweet corn (Zea mays var. saccharata), and how do I control it?

Watch for fall armyworm and corn earworm on developing ears; small holes in kernels and ragged silk tips are common signs. Hand-remove affected silks early, apply a BT (Bacillus thuringiensis) product when caterpillars are actively feeding, and check plants every 2–3 days around tassel and silk emergence so treatment hits before larvae bore deep. If you see widespread leaf spotting or rust, remove heavily infected leaves and keep plants spaced for airflow because crowded sweet corn stays wet longer.

How often should I water sweet corn during the main growing phase?

During tasseling and ear fill (roughly mid-season through maturity, around weeks 6–10), keep soil consistently moist but not soggy: about 1 inch (2.5 cm) of water per week, split into 2–3 deep waterings if it’s hot or windy. Water at the base and avoid wetting the leaves to reduce disease; dry spells during ear development cause stunted ears and poor kernel sweetness.

How can I tell when Argent sweet corn is ready to harvest?

Harvest when silks have mostly turned brown and the kernels are in the “milk” stage—puncture a kernel with your thumbnail; the liquid should be milky, not watery or doughy. Start checking around 70–75 days after sowing (since this type commonly reaches maturity near day 75) and harvest promptly once the ears hit milk stage for the best sweetness.

Silken tassels and tightly wrapped husks give way to kernels of luminous, creamy-white sweetness—bright as moonlight on the cob. Argent’s ears develop with a refined, uniform rowing and a tender, juicy bite that turns especially delightful when enjoyed at peak freshness. Grow Argent for garden-to-table moments where its pale kernels shine in salads, steaming platters, and buttery summer spreads, or for spoon-bright sauces and quick pickling-style preserves.

Sowing Tips

Transplant Conditions

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

Expert Note

Plant sweet corn in blocks (not single rows) and keep soil moisture consistent from tassel through ear fill to maximize sweetness.
