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

How often should I water sweet corn during the main growing phase?
During the rapid growth phase (from tasseling through early ear development), keep soil evenly moist, targeting about 1 to 1.5 inches of water per week total (more in hot weather). Water deeply so moisture reaches the root zone rather than frequent light sprinkling, and avoid letting the soil dry out between waterings because stress can shorten ear length and reduce kernel fill. A simple check: the top few inches should feel moist, not dry, before watering again.
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.

Sowing Tips

Soil Temperature

Direct sow or transplant when soil at planting depth holds 60°F for reliable germination and early growth.

Expert Note

Plant in blocks (not single rows) for reliable pollination and consistent ear fill.
