Care guide

Quick ID

Serendipity (sweet bicolor). Wind-pollinated, so plant in blocks of several short rows, not one long row, or ears fill poorly. Succession-plant (every 2–3 weeks) for staggered harvest.

Growing & Watering

Heavy feeder and thirsty, especially at tasseling/silking. Side-dress nitrogen at knee-high. Keep evenly watered through ear fill.

Harvest

~20 days after silks appear: silks brown and dry, ears feel full, and a punctured kernel runs milky. Sweet corn declines fast off the stalk — pick and use quickly.
