Seedling
7-10 daysTiny cotyledons emerge; first true leaves appear with characteristic lobed shape.
Keep soil moist but not soggy. Thin seedlings to proper spacing once first true leaves appear. Provide bright light to prevent leggy growth.
Vegetative
20-30 daysPlant develops 4-6 true leaves; compact rosette forms with progressively larger, deeply lobed leaves.
Water regularly to maintain consistent soil moisture. Begin light fertilizing with balanced or nitrogen-heavy fertilizer every 2-3 weeks. Monitor for pests and flea beetles.
Mid-Growth
10-15 daysPlant reaches 6-10 inches tall with dense foliage; leaves become more tender and flavorful.
Continue regular watering and feeding. Harvest outer leaves if desired to encourage fuller plant development. Provide afternoon shade in hot weather.
Harvest-Ready
5-10 daysPlant reaches full size with abundant tender leaves; typically 10-14 inches tall depending on variety.
Begin harvesting outer leaves or cut entire plant. Cool weather improves flavor and tenderness. Avoid harvesting more than 30% at once if wanting regrowth.
Bolting
Ongoing in warm weatherPlant begins to flower and set seed as temperatures warm; leaves become tougher and more bitter.
Once bolting begins, quality declines. Remove bolting plants to prevent cross-pollination with other brassicas. Save seed if desired from mature plants.

Harvest Tips
Begin harvesting outer leaves when plant is 6-8 inches tall, or wait until full size (10-14 inches) for complete harvest. Use a sharp knife to cut leaves 1-2 inches above the soil line. Harvest in the morning after dew dries for best crispness and flavor. Young, tender leaves are most flavorful. For continuous harvest, pick outer leaves weekly and the plant will produce new leaves. Cool weather (below 70°F) produces the most tender, mildest-flavored leaves.
