Sunlit kernels with a buttery, lemon-gold glow—Lemonade sweet corn brings a vivid sweetness that feels bright on the palate. At maturity, the ears form a medium-to-large, gently tapered silhouette with plump rows of tender, juicy kernels and a fine, creamy bite. Grow Lemonade for fresh harvest enjoyment, and for golden summer sauces and quick pickling-style preserves where its sunny color and sweet corn flavor shine.

Frequently Asked Questions

What’s a common pest or disease in Zea mays var. saccharata (sweet corn) and how can I manage it?
Watch for corn earworm (Helicoverpa zea), which feeds through the silks and damages kernels. Start by applying Bt (Bacillus thuringiensis) when silks first appear and reapply as labeled; remove and discard heavily damaged ears and keep the garden free of weeds that harbor pests. If you also see fungal issues like grayish mold on ear tips, harvest promptly when ears mature and avoid overhead watering to reduce moisture on silks.
How do I tell when Lemonade (Zea mays var. saccharata) sweet corn is ready to harvest?
Harvest when silks are browned and the kernels feel plump and release milky juice when pierced with a fingernail—this is the sweet-corn maturity sweet spot. Check an ear about 70 days after sowing (then adjust by silk color and kernel milk), and pick during the morning for the sweetest flavor.

Sowing Tips

Soil Temperature

Direct sow or transplant when soil at planting depth holds 55°F for reliable germination and early growth.

Expert Note

Plant sweet corn in a block (not a single row) so wind can move pollen between plants for full ear set.
