HOW TO GROW CORNS

Golden Rules for Growing Corn

1. Full sun is essential
2. Plant in blocks for pollination
3. Feed heavily
4. Keep soil consistently moist
5. Harvest sweet corn quickly for best flavor

1. Choose a Variety

Sweet corn is the easiest and best for home eating. Choose early or dwarf varieties for smaller gardens.

Easy beginner varieties:

• Golden Bantam
• Honey Bantam
• Golden Nugget
• Sweet Success

2. Growing Timeline

Month	Growth Stage	Tasks
July	Preparation Stage	Choose a sunny spot (corn needs full sun). Improve soil with compost and manure. Make soil loose and well-drained.
August	Early Preparation / Optional Start	In warmer areas, you can start sowing late August. Otherwise continue preparing soil and beds.
September	Planting Stage	Sow corn seeds directly into soil. Plant in blocks (not single rows) for better pollination. Water well after planting.
October	Germination & Seedling Stage	Seeds sprout. Keep soil moist. Remove weeds. Thin weak seedlings if needed.
November	Vegetative Growth Stage	Corn grows fast and tall. Feed with nitrogen-rich fertilizer. Water deeply and regularly.
December	Rapid Growth Stage	Plants grow tall stalks and leaves. Start light hilling (mounding soil around base for support).
January	Tasseling & Pollination Stage	Tassels (male flowers) appear at top. Silks appear on ears. Shake plants gently for better pollination if needed.
February	Cob Development Stage	Corn cobs fill out and enlarge. Keep watering consistently. Protect from pests like birds.
March	Harvest Stage	Harvest when kernels are full and milky when pressed. Pick early in morning for best sweetness.
April	Late Harvest / Cleanup	Finish harvesting remaining cobs. Remove old plants. Compost healthy stalks.
May	Soil Recovery Stage	Add compost and organic matter. Rotate crops to avoid pests and soil depletion.
June	Rest Stage	Garden rest period. Plan next planting cycle and improve soil structure.

3. Soil & Pots

• Soil: Corns are heavy feeders. Soil needs to be rich in compost, loose and well-draining (6 – 7ph).
• Corn can grow in a container.

4. Planting

Corn is generally considered easy to grow but main challenge is planting in blocks (not single rows) for proper wind pollination.

1. Sowing Seeds:

• Plant 2-4cm deep
• Spacing: 20-30cm between plants and 60-90cm between rows
• Water deeply.

2. Germination usually takes 7–14 days.

5. Sun & Watering

Pumpkin needs:

• 6–8+ hours sun daily
• Warm temperature

Watering Rules: Corn needs consistent moisture.

• Water deeply
• Avoid drying out during flowering
• Mulch helps retain moisture

Stage	Water Need
Germination	Moderate
Fast growth	High
Tasseling & cob formation	Very high

6. Supporting & Pruning

Corn usually needs very little pruning, but proper support can help prevent plants from falling over, especially in windy or storm-prone areas like Sydney during summer.

7. Feeding

Corn benefits from nitrogen-rich fertilizer.

When preparing the soil, add:

• Compost
• Aged manure (avoid fresh manure)
• Organic fertilizer

Feed when

• Seedlings are established
• Plants are knee-high
• Before tasseling

Good options:

• Compost tea
• Blood & bone
• Fish emulsion
• Nitrogen fertilizer

8. Pollination

• Corn is wind-pollinated:
• Tassels (top) release pollen and silks (on cob) catch pollen
• Poor pollination = missing kernels. You can help by Gently shaking plants and growing in blocks

9. Common Problems

Problem	Cause
Yellow leaves	Lack of nitrogen
Missing kernels	Poor pollination
Small cobs	Low nutrients/water
Worms in cobs	Corn earworm
Plants falling over	Wind or shallow roots

10. Harvesting

Sweet corn harvest when

• Silks turn brown
• Kernels release milky juice when pressed
• Cobs feel full

Typical timing

• 60–100 days depending on variety

10. Storage

Simple Rule for Beginners

• Sweet corn → refrigerate or freeze quickly
• Dry corn → keep cool and dry
• Seeds → dry thoroughly before storage
• Moisture is the main enemy of stored corn grain and seeds

Corn Type	Method	Storage Life
Fresh sweet corn	Refrigerate	1–5 days
Frozen corn	Freeze	8–12 months
Dried corn	Airtight container	1+ year
Popcorn	Cool dry storage	1–2 years
Seed corn	Cool dry storage	1–3 years

Common Storage Mistake

Mistake	Result
Leaving sweet corn warm	Rapid sugar loss
Freezing without blanching	Poor texture
Storing damp dried corn	Mold
Poor airflow during drying	Rot
Sun exposure	Kernel damage

Storing Fresh Sweet Corn (Short-Term)

• Store corn in the refrigerator inside a plastic bag or container with husks on.
• Refrigerate immediately after picking not to lose sugars.
• Eat as soon as possible

Freezing Corn

1. Remove husks and silk
2. Blanch in boiling water:
   • Small cobs: 7 minutes
   • Medium: 9 minutes
   • Large: 11 minutes
3. Cool in ice water
4. Dry thoroughly
5. Freeze in airtight bags

Freezing Corn Kernels

1. Blanch cobs
2. Cool
3. Cut kernels off cob
4. Freeze in portions

Drying Corn

• Leave cobs on plant until dry if weather allows Or dry indoors in airy space.
• Used for popcorn or seed storage.

Storing Popcorn

Factor	Ideal
Container	Airtight
Location	Cool, dry
Humidity	Moderate-low

*Popcorn needs a little internal moisture to pop properly.

Seed Corn Storage

For planting next season

• Dry completely
• Store in airtight container
• Keep cool and dry

Good storage places

• Refrigerator
• Cool pantry
• Dry cupboard
