Growth Stages

1

Seedling

7-10 days

Tiny cotyledons emerge; first true leaves appear heart-shaped and smooth.

Keep soil moist and provide consistent light. Thin seedlings to proper spacing once they have 2-3 true leaves. Protect from heavy rain and wind.

2

Vegetative Growth

15-25 days

Characteristic lobed, frilly leaves develop rapidly; plant forms a loose rosette.

Maintain consistent moisture and apply nitrogen-rich fertilizer every 2-3 weeks. Mulch around base to conserve moisture and keep leaves clean.

3

Peak Harvest

5-15 days

Leaves are full-sized, tender, and deeply lobed with vibrant green color; plant reaches market maturity.

Begin harvesting outer leaves to encourage continued production. Monitor for heat stress in warm weather; afternoon shade helps in warm climates.

4

Bolting

7-14 days

Plant elongates and produces a flowering stem; leaves become tougher and more bitter.

This signals the end of the productive harvest period. Plant in spring and fall to avoid bolting in summer heat. Remove and replant if desired.

Common Pests

  • Use row covers until plants are established. Apply neem oil or insecticidal soap. Diatomaceous earth around base. Plant resistant varieties if available.

  • Hand-pick caterpillars. Use row covers to prevent adult moths from laying eggs. Apply Bacillus thuringiensis (Bt). Encourage beneficial wasps.

  • Spray with strong water stream to dislodge. Apply insecticidal soap or neem oil. Release ladybugs or lacewings as biological control.

  • Use yellow sticky traps. Apply insecticidal soap. Introduce parasitic wasps. Maintain good air circulation.

  • Rotate crops; avoid planting other brassicas in same spot for 4+ years. Improve soil drainage. Use resistant varieties if available. Lime soil to raise pH above 7.2.

Harvest Tips

Harvest leaves when they are young and tender, typically 30-50 days after planting. For cut-and-come-again harvesting, remove outer leaves from the base while plant is still growing. Harvest in morning after dew dries for best texture. Entire plant can be cut at soil level for a single harvest. Avoid harvesting after bolting begins, as quality declines.

Fun Facts
