Growth Stages

1

Germination & Seedling

2-3 weeks

Seeds sprout in 7-10 days, developing first true leaves. Young plants are tender with light green foliage.

Keep soil consistently moist but not soggy. Thin seedlings to 2-3 inches apart when first true leaves appear. Provide gentle light and moderate warmth (60-70°F).

2

Vegetative Growth

3-4 weeks

Plants develop multiple leaves in rosette form, growing 6-8 inches tall with increasing leaf production.

Maintain consistent moisture and provide full sun. Begin feeding with balanced fertilizer every 2-3 weeks. Thin to final spacing of 10 inches. Monitor for slugs and leaf beetles.

3

Head Formation

2-3 weeks

Leaves begin to cup inward, forming the characteristic compact head. Inner leaves gradually develop the deep red coloration with white veins.

Reduce watering frequency slightly to stress plants mildly and encourage heading. Ensure full sun exposure for best color development. Provide light feeding with potassium-rich fertilizer.

4

Maturation & Color Development

2-3 weeks

Heads become firm and fully formed with intense deep burgundy-red color and distinctive white veining throughout. Frost exposure enhances color.

Reduce water further to encourage firmness and deeper coloring. Light frost (32-40°F) actually improves color and flavor. Do not harvest prematurely; allow heads to reach full firmness.

5

Harvest Ready

Harvest window

Heads are compact, firm, and deeply colored with vibrant red-and-white patterning. Heads reach 3-4 inches in diameter.

Harvest when heads are firm and properly colored. Can withstand multiple light frosts. For storage, harvest in dry conditions and store at 32-40°F with high humidity.
