Bi-Color Blend Corn
Zea mays
vegetableBi-Color Blend is a sweet corn variety that produces ears with a mix of yellow and white kernels, offering a naturally sweet flavor and attractive appearance. The blend of kernel colors comes from crossing yellow and white corn varieties, creating visual interest and a slightly different taste profile than single-color varieties. This is a hybrid corn bred for home gardeners and farmers seeking both aesthetic appeal and superior sweetness.

Germination & Seedling
1-2 weeksSeeds sprout and emerge with 2-3 leaves visible above soil within 7-10 days.
Keep soil consistently moist but not waterlogged. Ensure warm soil temperatures (65°F+). Thin seedlings to proper spacing once they have 2-3 true leaves.
Vegetative Growth
3-4 weeksPlant develops 4-8 leaves, reaches 12-24 inches tall, and establishes a strong root system.
Side-dress with nitrogen fertilizer when plants reach 12 inches tall. Keep weeds down. Mulch around base to retain moisture and regulate temperature.
Pre-Flowering & Tassel Development
2-3 weeksPlant reaches 3-5 feet tall, tassel appears at the top, and silk emerges from the ear.
Maintain consistent deep watering (critical stage). Apply balanced fertilizer. Watch for pest activity. Remove any suckers at the base to direct energy to ears.
Flowering & Silking
2-3 weeksTassel releases pollen, silks emerge from ears and become brown/dry as kernels develop and fill.
Water deeply and consistently. Do NOT let soil dry out during this critical stage. Avoid overhead watering to reduce disease. Monitor for corn borers and other pests.
Kernel Fill & Maturity
2-3 weeksKernels plump up and develop their bi-color appearance (yellow and white). Silk dries completely and turns brown.
Reduce watering slightly once silks are completely brown. Avoid excessive nitrogen, which can extend maturity. Check ears regularly for harvest readiness by feeling the cob and checking kernel firmness.

Common Pests
-
Use Bt (Bacillus thuringiensis) spray when borers are active. Plant resistant varieties. Remove and destroy affected plant parts. Use pheromone traps for monitoring.
-
Apply Bt spray to silks when they first appear. Use neem oil. Hand-pick worms if infestation is light. Encourage beneficial parasitic wasps.
-
Spray with water to dislodge. Use insecticidal soap or neem oil. Encourage ladybugs and lacewings with flowering companion plants.
-
Increase humidity through consistent watering. Spray with neem oil or miticide. Remove heavily infested leaves.
-
Apply Bt spray to whorl (top of plant) and silks. Use spinosad if Bt-resistant populations present. Hand-pick and destroy larvae.
Uses
Fresh Eating & Cooking
CulinaryBi-Color Blend is ideal for boiling, roasting, grilling, or eating raw. The blend of yellow and white kernels provides a visually striking presentation on the plate, making it popular for gatherings and restaurants. [source]

Compost & Garden Amendments
HouseholdSpent corn stalks, cobs, and leaves are excellent additions to compost piles, breaking down to enrich soil with organic matter. Corn cobs can be used as mulch or bedding. [source]
Decorative & Craft Use
CraftThe bi-color ears are attractive for fall decorations, harvest displays, and crafts. Dried corn husks can be used for weaving and traditional crafts. [source]
Wildlife Food Source
WildlifeCorn is an important food source for birds, squirrels, and other wildlife. Leaving some ears on the stalk or planting extra supports local fauna. [source]
Harvest Tips
Harvest when silks are dry and brown, ears are firm when gently squeezed, and kernels release a milky juice when punctured (milk stage). Typically 20 days after silking. Pick by twisting and pulling downward. Harvest in the early morning for best sweetness. Use within 24 hours for peak flavor, though refrigeration can extend freshness. Both ears and corn stalks can be used for various purposes.
Fun Facts
- 🌱 Bi-color corn was commercially introduced in the 1980s and has become increasingly popular because it offers visual appeal combined with superior sweetness from heterozygote vigor (hybrid vigor).
- 🌱 Corn is technically a grain crop, not a vegetable—it's only called 'sweet corn' to distinguish it from field corn, which is harvested when fully mature and starchy.
- 🌱 A single corn plant can produce 1-4 ears depending on variety, growing conditions, and plant vigor; Bi-Color Blend typically produces 1-2 ears per plant.
