Early Sunglow

Corn

70d to harvest

Sun-warmed and irresistibly sweet, Early Sunglow brings a bright, golden harvest with kernels that burst tenderly and melt into a silky bite. The ears form with a classic, well-filled silhouette and a smooth, juicy texture that stays crisp in the garden’s first golden weeks. Grow it for fresh-picked enjoyment and for vibrant, sunshine-bright corn-on-the-cob moments, plus richly colored results in creamy sauces and quick pickling-style preserves.

Frequently Asked Questions

What pest or disease commonly affects Zea mays (sweet corn) and how can I prevent it?

Sweet corn commonly suffers from corn earworm and fall armyworm, which bore into developing ears and damage kernels. Scout plants 2–3 times weekly from tassel to early ear fill; use pheromone traps for monitoring and apply an appropriate Bt corn earworm product when larvae are small, following the label. Prevent fungal issues like gray leaf spot by spacing plants for airflow and watering at the base so leaves stay dry during the day.

How do I tell when sweet corn is ready to harvest (Zea mays var. saccharata)?

Harvest when the silks have browned and pull away easily, and the kernels are filled to the tip of the ear. Do the “milk” test: press a kernel—if a milky fluid squirts out, it’s ready; if it’s watery or no liquid forms, wait a bit. For best sweetness, pick in the morning and harvest soon after kernels reach the milk stage; once over-mature, sugar converts to starch quickly in sweet corn.
